In the pecking order of natural sleep aids, magnesium seems to be steadily making its way to the top. This essential mineral plays multiple roles in the body, but what does it do for sleep? There is some evidence, both clinical and anecdotal, that magnesium may be helpful for better sleep, but details are still murky. To get a better idea of how exactly magnesium and sleep could be connected, we spoke with a certified sleep expert and a registered nutritionist.

What Is Magnesium?

“Magnesium is a mineral we need in our diet to stay healthy,” explains Dr. Chelsie Rohrscheib, a neuroscientist and the head sleep expert at Wesper. It’s classified as an electrolyte and involved in over 300 enzymatic processes in the body, including supporting bone health, regulating muscle function, and promoting energy production.

The body doesn’t make its own magnesium, which means we need to source sufficient amounts from the foods we eat or the supplements we take. The mineral is present in nutritious foods like fruits and vegetables, fish, nuts, seeds, legumes and whole grains. Still, a 2018 review found that an estimated 50 percent of Americans may be deficient. While it’s not necessarily life threatening, a magnesium deficiency can have unpleasant symptoms, such as muscle cramps, tremors and twitches — none of which make it easy to fall or stay asleep.

How Does Magnesium Affect Sleep?

Susan Schachter, MSRDN, calls magnesium a smooth muscle relaxer, which means it can help calm the nervous system. “It has been shown to increase levels of the neurotransmitter GABA, which helps calm the brain and reduce anxiety,” she explains. “Because of this, research has suggested that magnesium may help improve sleep quality, reduce insomnia, and increase sleep time in people with some sleep disorders.”

In fact, it’s often recommended to people who struggle with muscle cramps at night or those with restless legs syndrome, says Rohrscheib. But that’s not all.

“In addition to its involvement in reducing anxiety, relaxing muscle and increasing levels of GABA, magnesium helps to regulate the body’s production of melatonin, a hormone that’s important for sleep-wake cycles,” says Schachter.

While several small studies show a positive association between magnesium and improved sleep quality and duration, research about the actual impact of magnesium on sleep is still quite limited. What’s more, findings are mixed. A 2021 review of magnesium supplementation for insomnia in older adults found that sleep latency and total sleep time improved, but researchers called the results statistically insignificant and noted that outcomes were supported with poor quality of evidence.

How to Take Magnesium

As a potential sleep aid, magnesium can be taken as an oral supplement about 30 minutes to an hour before bed. It comes in several forms, including magnesium oxide, magnesium citrate and magnesium chloride, and absorption can vary based on the type used in a given supplement. Some studies have found that citrate and chloride forms of magnesium are more bioavailable than oxide — that means the body is able to more readily absorb those forms, which could mean greater efficacy.

Magnesium is also available in topical form, including lotions, sprays, and bath salts. While research is still needed to confirm the efficacy of topical magnesium as a sleep remedy, the application of a soothing magnesium lotion or a calming soak in a warm tub could still be a good addition to a bedtime routine.

How Much Magnesium Should I Take for Sleep?

Keep in mind that we get magnesium in our diets, and it’s an essential mineral for various bodily functions. The National Institutes of Health recommends that adults supplement with no more than 350 mg per day. That’s slightly at odds with dosages used in clinical studies of magnesium for sleep. “Some studies have shown that taking 200-400 mg before bed may help improve sleep quality and quantity, particularly in people who have difficulty falling asleep,” says Schachter.

Still, it’s best to err on the side of caution. “When supplementing one needs to be careful with dosing, as a high dose can cause diarrhea (because the intestines are smooth muscle) and/or upset stomach,” Schachter says.

Magnesium and Anxiety

There is research that suggests magnesium could be a viable treatment for anxiety, possibly because of the way it regulates neurotransmitters and brain function. Specifically, magnesium interacts with stress mediators like the hypothalamus, the part of the brain that manages stress and anxiety, by inhibiting the stress response. However, like magnesium as a sleep aid, more research is needed to clarify how exactly magnesium can help with anxiety.

How Can I Raise My Magnesium Levels Naturally?

Generally, you can increase magnesium levels through diet alone, because it’s present in a fairly wide range of foods. The federal government’s Dietary Guidelines for Americans outlines a healthy diet as one that includes a mix of vegetables, fat and low-fat dairy, beans and legumes, and nuts and seeds, all of which include magnesium.

Foods High In Magnesium

Schachter says that the amount of magnesium in specific foods can vary depending on how they’re processed and prepared, but the following are great sources:

• Dark leafy greens: spinach, kale, Swiss chard, collard greens
• Nuts and seeds: almonds, cashews, pumpkin seeds, sunflower seeds
• Legumes: black beans, kidney beans, chickpeas, lentils
• Whole grains: brown rice, quinoa (actually a seed but used like a grain), whole wheat products
• Fish: halibut, salmon, mackerel
• Dairy products: milk, yogurt, cheese
• Soy Products: soy milk, soy beans
• Dark chocolate

Is Magnesium Better Than Melatonin?

Magnesium is inherently different from melatonin. One is an essential mineral that we need to source from the foods we eat, while the other is a hormone that we produce naturally. Schachter says they can both potentially help with sleep, and the two substances share a deeper connection as well. “Magnesium has the benefit of helping with melatonin production, as well as decreasing anxiety and relaxing muscles,” she says.

It isn’t that one is necessarily better than the other, but rather that they offer different benefits. Melatonin supplements help jumpstart your natural melatonin production, which can make it easier to fall asleep in certain scenarios, like if you’re dealing with jet lag, trying to sleep in a new environment, or navigating short-term insomnia. Magnesium can be a better option if you need to shut down an anxious mind so that your body can relax into sleep.

The Last Word from Sleepopolis

Magnesium rivals melatonin as a popular natural sleep aid, and there is promising research to support its role in better sleep. However, more studies are needed to pinpoint exactly how magnesium supports sleep. If you’re considering this supplement to help you get a better night’s sleep, make sure to speak with your doctor first. “It’s always important to check with a healthcare professional to be sure magnesium is safe for you if you have any health conditions or are taking medication,” says Schachter. source

Magnesium Introduction

Magnesium, an abundant mineral in the body, is naturally present in many foods, added to other food products, available as a dietary supplement, and present in some medicines (such as antacids and laxatives). Magnesium is a cofactor in more than 300 enzyme systems that regulate diverse biochemical reactions in the body, including protein synthesis, muscle and nerve function, blood glucose control, and blood pressure regulation [1-3]. Magnesium is required for energy production, oxidative phosphorylation, and glycolysis. It contributes to the structural development of bone and is required for the synthesis of DNA, RNA, and the antioxidant glutathione. Magnesium also plays a role in the active transport of calcium and potassium ions across cell membranes, a process that is important to nerve impulse conduction, muscle contraction, and normal heart rhythm [3].

An adult body contains approximately 25 g magnesium, with 50% to 60% present in the bones and most of the rest in soft tissues [4]. Less than 1% of total magnesium is in blood serum, and these levels are kept under tight control. Normal serum magnesium concentrations range between 0.75 and 0.95 millimoles (mmol)/L [1,5]. Hypomagnesemia is defined as a serum magnesium level less than 0.75 mmol/L [6]. Magnesium homeostasis is largely controlled by the kidney, which typically excretes about 120 mg magnesium into the urine each day [2]. Urinary excretion is reduced when magnesium status is low [1].

Assessing magnesium status is difficult because most magnesium is inside cells or in bone [3]. The most commonly used and readily available method for assessing magnesium status is measurement of serum magnesium concentration, even though serum levels have little correlation with total body magnesium levels or concentrations in specific tissues [6]. Other methods for assessing magnesium status include measuring magnesium concentrations in erythrocytes, saliva, and urine; measuring ionized magnesium concentrations in blood, plasma, or serum; and conducting a magnesium-loading (or tolerance) test. No single method is considered satisfactory [7]. Some experts [4] but not others [3] consider the tolerance test (in which urinary magnesium is measured after parenteral infusion of a dose of magnesium) to be the best method to assess magnesium status in adults. To comprehensively evaluate magnesium status, both laboratory tests and a clinical assessment might be required [6].

Recommended Intakes

Intake recommendations for magnesium and other nutrients are provided in the Dietary Reference Intakes (DRIs) developed by the Food and Nutrition Board (FNB) at the Institute of Medicine of the National Academies (formerly National Academy of Sciences) [1]. DRI is the general term for a set of reference values used to plan and assess nutrient intakes of healthy people. These values, which vary by age and sex, include the following:

• Recommended Dietary Allowance (RDA): Average daily level of intake sufficient to meet the nutrient requirements of nearly all (97%–98%) healthy individuals; often used to plan nutritionally adequate diets for individuals
• Adequate Intake (AI): Intake at this level is assumed to ensure nutritional adequacy; established when evidence is insufficient to develop an RDA
• Estimated Average Requirement (EAR): Average daily level of intake estimated to meet the requirements of 50% of healthy individuals; usually used to assess the nutrient intakes of groups of people and to plan nutritionally adequate diets for them; can also be used to assess the nutrient intakes of individuals
• Tolerable Upper Intake Level (UL): Maximum daily intake unlikely to cause adverse health effects

Table 1 lists the current RDAs for magnesium [1]. For infants from birth to 12 months, the FNB established an AI for magnesium that is equivalent to the mean intake of magnesium in healthy, breastfed infants, with added solid foods for ages 7–12 months.

Sources of Magnesium

Food

Magnesium is widely distributed in plant and animal foods and in beverages. Green leafy vegetables, such as spinach, legumes, nuts, seeds, and whole grains, are good sources [1,3]. In general, foods containing dietary fiber provide magnesium. Magnesium is also added to some breakfast cereals and other fortified foods. Some types of food processing, such as refining grains in ways that remove the nutrient-rich germ and bran, lower magnesium content substantially [1]. Selected food sources of magnesium are listed in Table 2.

Tap, mineral, and bottled waters can also be sources of magnesium, but the amount of magnesium in water varies by source and brand (ranging from 1 mg/L to more than 120 mg/L) [8].

Approximately 30% to 40% of the dietary magnesium consumed is typically absorbed by the body [2,9].

*DV = Daily Value. The U.S. Food and Drug Administration (FDA) developed DVs to help consumers compare the nutrient contents of foods and dietary supplements within the context of a total diet. The DV for magnesium is 420 mg for adults and children age 4 years and older [11]. FDA does not require food labels to list magnesium content unless magnesium has been added to the food. Foods providing 20% or more of the DV are considered to be high sources of a nutrient, but foods providing lower percentages of the DV also contribute to a healthful diet.

The U.S. Department of Agriculture’s (USDA’s) FoodData Central [10] lists the nutrient content of many foods and provides comprehensive list of foods containing magnesium arranged by nutrient content and by food name.

Dietary supplements

Magnesium supplements are available in a variety of forms, including magnesium oxide, citrate, and chloride [2,3]. The Supplement Facts panel on a dietary supplement label declares the amount of elemental magnesium in the product, not the weight of the entire magnesium-containing compound.

Absorption of magnesium from different kinds of magnesium supplements varies. Forms of magnesium that dissolve well in liquid are more completely absorbed in the gut than less soluble forms [2,12]. Small studies have found that magnesium in the aspartate, citrate, lactate, and chloride forms is absorbed more completely and is more bioavailable than magnesium oxide and magnesium sulfate [12-16]. One study found that very high doses of zinc from supplements (142 mg/day) can interfere with magnesium absorption and disrupt the magnesium balance in the body [17].

Medicines

Magnesium is a primary ingredient in some laxatives [18]. Phillips’ Milk of Magnesia, for example, provides 500 mg elemental magnesium (as magnesium hydroxide) per tablespoon; the directions advise taking up to 4 tablespoons/day for adolescents and adults [19]. (Although such a dose of magnesium is well above the safe upper level, some of the magnesium is not absorbed because of the medication’s laxative effect.) Magnesium is also included in some remedies for heartburn and upset stomach due to acid indigestion [18]. Extra-strength Rolaids, for example, provides 55 mg elemental magnesium (as magnesium hydroxide) per tablet [20], although Tums is magnesium free [21].

Magnesium Intakes and Status

Dietary surveys of people in the United States consistently show that many people consume less than recommended amounts of magnesium. An analysis of data from the National Health and Nutrition Examination Survey (NHANES) of 2013–2016 found that 48% of Americans of all ages ingest less magnesium from food and beverages than their respective EARs; adult men age 71 years and older and adolescent males and females are most likely to have low intakes [22]. In a study using data from NHANES 2003–2006 to assess mineral intakes among adults, average intakes of magnesium from food alone were higher among users of dietary supplements (350 mg for men and 267 mg for women, equal to or slightly exceeding their respective EARs) than among nonusers (268 mg for men and 234 for women) [23]. When supplements were included, average total intakes of magnesium were 449 mg for men and 387 mg for women, well above EAR levels.

No current data on magnesium status in the United States are available. Determining dietary intake of magnesium is the usual proxy for assessing magnesium status. NHANES has not determined serum magnesium levels in its participants since 1974 [24], and magnesium is not evaluated in routine electrolyte testing in hospitals and clinics [2].

Magnesium Deficiency

Symptomatic magnesium deficiency due to low dietary intake in otherwise-healthy people is uncommon because the kidneys limit urinary excretion of this mineral [3]. However, habitually low intakes or excessive losses of magnesium due to certain health conditions, chronic alcoholism, and/or the use of certain medications can lead to magnesium deficiency.

Early signs of magnesium deficiency include loss of appetite, nausea, vomiting, fatigue, and weakness. As magnesium deficiency worsens, numbness, tingling, muscle contractions and cramps, seizures, personality changes, abnormal heart rhythms, and coronary spasms can occur [1,2]. Severe magnesium deficiency can result in hypocalcemia or hypokalemia (low serum calcium or potassium levels, respectively) because mineral homeostasis is disrupted [2].

Groups at Risk of Magnesium Inadequacy

Magnesium inadequacy can occur when intakes fall below the RDA but are above the amount required to prevent overt deficiency. The following groups are more likely than others to be at risk of magnesium inadequacy because they typically consume insufficient amounts or they have medical conditions (or take medications) that reduce magnesium absorption from the gut or increase losses from the body.

People with gastrointestinal diseases

The chronic diarrhea and fat malabsorption resulting from Crohn’s disease, gluten-sensitive enteropathy (celiac disease), and regional enteritis can lead to magnesium depletion over time [2]. Resection or bypass of the small intestine, especially the ileum, typically leads to malabsorption and magnesium loss [2].

People with type 2 diabetes

Magnesium deficits and increased urinary magnesium excretion can occur in people with insulin resistance and/or type 2 diabetes [25,26]. The magnesium loss appears to be secondary to higher concentrations of glucose in the kidney that increase urine output [2].

People with alcohol dependence

Magnesium deficiency is common in people with chronic alcoholism [2]. In these individuals, poor dietary intake and nutritional status; gastrointestinal problems, including vomiting, diarrhea, and steatorrhea (fatty stools) resulting from pancreatitis; renal dysfunction with excess excretion of magnesium into the urine; phosphate depletion; vitamin D deficiency; acute alcoholic ketoacidosis; and hyperaldosteronism secondary to liver disease can all contribute to decreased magnesium status [2,27].

Older adults

Older adults have lower dietary intakes of magnesium than younger adults [21,28]. In addition, magnesium absorption from the gut decreases and renal magnesium excretion increases with age [29]. Older adults are also more likely to have chronic diseases or take medications that alter magnesium status, which can increase their risk of magnesium depletion [1,30].

Magnesium and Health

Habitually low intakes of magnesium induce changes in biochemical pathways that can increase the risk of illness over time. This section focuses on four diseases and disorders in which magnesium might be involved: hypertension and cardiovascular disease, type 2 diabetes, osteoporosis, and migraine headaches.

Hypertension and cardiovascular disease

Hypertension is a major risk factor for heart disease and stroke. Studies to date, however, have found that magnesium supplementation lowers blood pressure, at best, to only a small extent. A meta-analysis of 12 clinical trials found that magnesium supplementation for 8–26 weeks in 545 hypertensive participants resulted in only a small reduction (2.2 mmHg) in diastolic blood pressure [31]. The dose of magnesium ranged from approximately 243 to 973 mg/day. The authors of another meta-analysis of 22 studies with 1,173 normotensive and hypertensive adults concluded that magnesium supplementation for 3–24 weeks decreased systolic blood pressure by 3–4 mmHg and diastolic blood pressure by 2–3 mmHg [32]. The effects were somewhat larger when supplemental magnesium intakes of the participants in the nine crossover-design trials exceeded 370 mg/day. A diet containing more magnesium because of added fruits and vegetables, more low-fat or nonfat dairy products, and less fat overall was shown to lower systolic and diastolic blood pressure by an average of 5.5 and 3.0 mmHg, respectively [33]. However, this Dietary Approaches to Stop Hypertension (DASH) diet also increases intakes of other nutrients, such as potassium and calcium, that are associated with reductions in blood pressure, so any independent contribution of magnesium cannot be determined.

In 2022, FDA approved a qualified health claim for conventional foods and dietary supplements that contain magnesium [34]. One example of this claim states, “Consuming diets with adequate magnesium may reduce the risk of high blood pressure (hypertension). However, FDA has concluded that the evidence is inconsistent and inconclusive.” FDA also specifies that foods and dietary supplements carrying this claim on their labels must provide at least 84 mg of magnesium per serving and, for dietary supplements, no more than 350 mg.

Several prospective studies have examined associations between magnesium intakes and heart disease. The Atherosclerosis Risk in Communities study assessed heart disease risk factors and levels of serum magnesium in a cohort of 14,232 White and African-American men and women age 45 to 64 years at baseline [35]. Over an average of 12 years of follow-up, individuals in the highest quartile of the normal physiologic range of serum magnesium (at least 0.88 mmol/L) had a 38% reduced risk of sudden cardiac death compared with individuals in the lowest quartile (0.75 mmol/L or less). However, dietary magnesium intakes had no association with risk of sudden cardiac death. Another prospective study tracked 88,375 female nurses in the United States to determine whether serum magnesium levels measured early in the study and magnesium intakes from food and supplements assessed every 2 to 4 years were associated with sudden cardiac death over 26 years of follow-up [36]. Women in the highest compared with the lowest quartile of ingested and plasma magnesium concentrations had a 34% and 77% lower risk of sudden cardiac death, respectively. Another prospective population study of 7,664 adults age 20 to 75 years in the Netherlands who did not have cardiovascular disease found that low urinary magnesium excretion levels (a marker for low dietary magnesium intake) were associated with a higher risk of ischemic heart disease over a median follow-up period of 10.5 years. Plasma magnesium concentrations were not associated with risk of ischemic heart disease [37]. A systematic review and meta-analysis of prospective studies found that higher serum levels of magnesium were significantly associated with a lower risk of cardiovascular disease, and higher dietary magnesium intakes (up to approximately 250 mg/day) were associated with a significantly lower risk of ischemic heart disease caused by a reduced blood supply to the heart muscle [38].

Higher magnesium intakes might reduce the risk of stroke. In a meta-analysis of seven prospective trials with a total of 241,378 participants, an additional 100 mg/day magnesium in the diet was associated with an 8% decreased risk of total stroke, especially ischemic rather than hemorrhagic stroke [39]. One limitation of such observational studies, however, is the possibility of confounding with other nutrients or dietary components that could also affect the risk of stroke.

A large, well-designed clinical trial is needed to better understand the contributions of magnesium from food and dietary supplements to heart health and the primary prevention of cardiovascular disease [40].

Type 2 diabetes

Diets with higher amounts of magnesium are associated with a significantly lower risk of diabetes, possibly because of the important role of magnesium in glucose metabolism [41,42]. Hypomagnesemia might worsen insulin resistance, a condition that often precedes diabetes, or it might be a consequence of insulin resistance [43]. Diabetes leads to increased urinary losses of magnesium, and the subsequent magnesium inadequacy might impair insulin secretion and action, thereby worsening diabetes control [3].

Most investigations of magnesium intake and risk of type 2 diabetes have been prospective cohort studies. A meta-analysis of seven of these studies, which included 286,668 patients and 10,912 cases of diabetes over 6 to 17 years of follow-up, found that a 100 mg/day increase in total magnesium intake decreased the risk of diabetes by a statistically significant 15% [41]. Another meta-analysis of eight prospective cohort studies that followed 271,869 men and women over 4 to 18 years found a significant inverse association between magnesium intake from food and risk of type 2 diabetes; the relative risk reduction was 23% when the highest to lowest intakes were compared [44].

A 2011 meta-analysis of prospective cohort studies of the association between magnesium intake and risk of type 2 diabetes included 13 studies with a total of 536,318 participants and 24,516 cases of diabetes [45]. The mean length of follow-up ranged from 4 to 20 years. Investigators found an inverse association between magnesium intake and risk of type 2 diabetes in a dose-responsive fashion, but this association achieved statistical significance only in individuals who were overweight (body mass index [BMI] 25 or higher) but not in normal-weight individuals (BMI less than 25). Again, a limitation of these observational studies is the possibility of confounding with other dietary components or lifestyle or environmental variables that are correlated with magnesium intake.

Only a few small, short-term clinical trials have examined the potential effects of supplemental magnesium on control of type 2 diabetes and the results are conflicting [42,46]. For example, 128 patients with poorly controlled diabetes in a Brazilian clinical trial received a placebo or a supplement containing either 500 mg/day or 1,000 mg/day magnesium oxide (providing 300 or 600 mg elemental magnesium, respectively) [47]. After 30 days of supplementation, plasma, cellular, and urine magnesium levels increased in participants receiving the larger dose of the supplement, and their glycemic control improved. In another small trial in Mexico, participants with type 2 diabetes and hypomagnesemia who received a liquid supplement of magnesium chloride (providing 300 mg/day elemental magnesium) for 16 weeks showed significant reductions in fasting glucose and glycosylated hemoglobin concentrations compared with participants receiving a placebo, and their serum magnesium levels became normal [48]. In contrast, neither a supplement of magnesium aspartate (providing 369 mg/day elemental magnesium) nor a placebo taken for 3 months had any effect on glycemic control in 50 patients with type 2 diabetes who were taking insulin [49].

The American Diabetes Association states that there is insufficient evidence to support the routine use of magnesium to improve glycemic control in people with diabetes [46]. It further notes that there is no clear scientific evidence that vitamin and mineral supplementation benefits people with diabetes who do not have underlying nutritional deficiencies.

Osteoporosis

Magnesium is involved in bone formation and influences the activities of osteoblasts and osteoclasts [50]. Magnesium also affects the concentrations of both parathyroid hormone and the active form of vitamin D, which are major regulators of bone homeostasis. Several population-based studies have found positive associations between magnesium intake and bone mineral density in both men and women [51]. Other research has found that women with osteoporosis have lower serum magnesium levels than women with osteopenia and those who do not have osteoporosis or osteopenia [52]. These and other findings indicate that magnesium deficiency might be a risk factor for osteoporosis [50].

Although limited in number, studies suggest that increasing magnesium intakes from food or supplements might increase bone mineral density in postmenopausal and elderly women [1]. For example, one short-term study found that 290 mg/day elemental magnesium (as magnesium citrate) for 30 days in 20 postmenopausal women with osteoporosis suppressed bone turnover compared with placebo, suggesting that bone loss decreased [53].

Diets that provide recommended levels of magnesium enhance bone health, but further research is needed to elucidate the role of magnesium in the prevention and management of osteoporosis.

Migraine headaches

Magnesium deficiency is related to factors that promote headaches, including neurotransmitter release and vasoconstriction [54]. People who experience migraine headaches have lower levels of serum and tissue magnesium than those who do not.

However, research on the use of magnesium supplements to prevent or reduce symptoms of migraine headaches is limited. Three of four small, short-term, placebo-controlled trials found modest reductions in the frequency of migraines in patients given up to 600 mg/day magnesium [54]. The authors of a review on migraine prophylaxis suggested that taking 300 mg magnesium twice a day, either alone or in combination with medication, can prevent migraines [55].

In their evidence-based guideline update, the American Academy of Neurology and the American Headache Society concluded that magnesium therapy is probably effective for migraine prevention [56]. Because the typical dose of magnesium used for migraine prevention exceeds the UL, this treatment should be used only under the direction and supervision of a health care provider.

Health Risks from Excessive Magnesium

Too much magnesium from food does not pose a health risk in healthy individuals because the kidneys eliminate excess amounts in the urine [29]. However, high doses of magnesium from dietary supplements or medications often result in diarrhea that can be accompanied by nausea and abdominal cramping [1]. Forms of magnesium most commonly reported to cause diarrhea include magnesium carbonate, chloride, gluconate, and oxide [12]. The diarrhea and laxative effects of magnesium salts are due to the osmotic activity of unabsorbed salts in the intestine and colon and the stimulation of gastric motility [57].

Very large doses of magnesium-containing laxatives and antacids (typically providing more than 5,000 mg/day magnesium) have been associated with magnesium toxicity [58], including fatal hypermagnesemia in a 28-month-old boy [59] and an elderly man [60]. Symptoms of magnesium toxicity, which usually develop after serum concentrations exceed 1.74–2.61 mmol/L, can include hypotension, nausea, vomiting, facial flushing, retention of urine, ileus, depression, and lethargy before progressing to muscle weakness, difficulty breathing, extreme hypotension, irregular heartbeat, and cardiac arrest [29]. The risk of magnesium toxicity increases with impaired renal function or kidney failure because the ability to remove excess magnesium is reduced or lost [1,29].

The FNB has established ULs for supplemental magnesium for healthy infants, children, and adults (see Table 3) [1]. For many age groups, the UL appears to be lower than the RDA. This occurs because the RDAs include magnesium from all sources—food, beverages, dietary supplements, and medications. The ULs include magnesium from only dietary supplements and medications; they do not include magnesium found naturally in food and beverages.

Interactions with Medications

Several types of medications have the potential to interact with magnesium supplements or affect magnesium status. A few examples are provided below. People taking these and other medications on a regular basis should discuss their magnesium intakes with their health care providers.

Bisphosphonates

Magnesium-rich supplements or medications can decrease the absorption of oral bisphosphonates, such as alendronate (Fosamax), used to treat osteoporosis [61]. Use of magnesium-rich supplements or medications and oral bisphosphonates should be separated by at least 2 hours [57].

Antibiotics

Magnesium can form insoluble complexes with tetracyclines, such as demeclocycline (Declomycin) and doxycycline (Vibramycin) as well as quinolone antibiotics, such as ciprofloxacin (Cipro) and levofloxacin (Levaquin). These antibiotics should be taken at least 2 hours before or 4–6 hours after a magnesium-containing supplement [57,62].

Diuretics

Chronic treatment with loop diuretics, such as furosemide (Lasix) and bumetanide (Bumex), and thiazide diuretics, such as hydrochlorothiazide (Aquazide H) and ethacrynic acid (Edecrin), can increase the loss of magnesium in urine and lead to magnesium depletion [63]. In contrast, potassium-sparing diuretics, such as amiloride (Midamor) and spironolactone (Aldactone), reduce magnesium excretion [63].

Proton pump inhibitors

Prescription proton pump inhibitor (PPI) drugs, such as esomeprazole magnesium (Nexium) and lansoprazole (Prevacid), when taken for prolonged periods (typically more than a year) can cause hypomagnesemia [64]. In cases that FDA reviewed, magnesium supplements often raised the low serum magnesium levels caused by PPIs. However, in 25% of the cases, supplements did not raise magnesium levels and the patients had to discontinue the PPI. FDA advises health care professionals to consider measuring patients’ serum magnesium levels prior to initiating long-term PPI treatment and to check magnesium levels in these patients periodically [64].

Magnesium and Healthful Diets

The federal government’s 2020–2025 Dietary Guidelines for Americans notes that “Because foods provide an array of nutrients and other components that have benefits for health, nutritional needs should be met primarily through foods. … In some cases, fortified foods and dietary supplements are useful when it is not possible otherwise to meet needs for one or more nutrients (e.g., during specific life stages such as pregnancy).”

For more information about building a healthy dietary pattern, refer to the Dietary Guidelines for Americans and the USDA’s MyPlate.

The Dietary Guidelines for Americans describes a healthy dietary pattern as one that

• Includes a variety of vegetables; fruits; grains (at least half whole grains); fat-free and low-fat milk, yogurt, and cheese; and oils.
  • Whole grains and dark-green, leafy vegetables are good sources of magnesium. Low-fat milk and yogurt contain magnesium as well. Some ready-to-eat breakfast cereals are fortified with magnesium.
• Includes a variety of protein foods such as lean meats; poultry; eggs; seafood; beans, peas, and lentils; nuts and seeds; and soy products.
  • ​​​​​​​Dried beans and legumes (such as soybeans, baked beans, lentils, and peanuts) and nuts (such as almonds and cashews) provide magnesium.
• Limits foods and beverages higher in added sugars, saturated fat, and sodium.
• Limits alcoholic beverages.
• Stays within your daily calorie needs.

It’s no secret that getting sufficient sleep is essential to maintaining good health. Sleeping is how the body recovers and repairs itself, so a lack of quality shut-eye can increase the risk of developing many health problems, including high blood pressure, heart disease, and depression, according to Medical News Today. However, all too often, people struggle with inadequate or poor quality sleep, leaving them tired, fatigued, and unable to perform at their best. While there are a lot of reasons behind this, diet actually plays a starring role in the quality of our sleep.

It turns out that eating the right foods before bed can actually help us fall asleep easier, stay asleep longer, and wake up feeling more energized and refreshed. Meghan Dillon, a registered dietitian nutritionist and HelloFresh nutrition associate, recently explained to Mashed why walnuts are a particularly good food to snack on before hitting the hay. Walnuts’ long list of nutrients can help encourage a good night’s rest while satisfying a craving for crunchiness.

Walnuts contain lots of sleep-promoting magnesium

Walnuts contain a high amount of magnesium, a nutrient that has been shown to be beneficial for sleep. Dillon explained to Mashed that eating foods high in magnesium can help activate the parasympathetic nervous system, which Simply Psychology reports is also known as the “rest and digest” system. This system helps the body enter a relaxed state, slowing down our breathing, decreasing our heart rate, prompting digestion, and lowering activity in the eyes, blood vessels, and other areas. If the parasympathetic nervous system is not activated, “we may feel stressed and tense, causing us to experience difficulty falling asleep as our body fails to relax properly,” Dillon said.

Magnesium also helps send the brain signals that calm down the nervous system, according to Healthline. Additionally, magnesium may aid in the production of melatonin, the hormone that controls the body’s sleep-wake cycle. According to Dillon, “Magnesium deficiency is associated with low serum melatonin, whereas sufficient serum magnesium is associated with adequate serum melatonin.” Therefore, she recommends eating walnuts, as well as other magnesium-rich foods, like pumpkin seeds, peanuts, and cashews, to help promote healthy sleep.

Walnuts are a good source of omega-3 fatty acids

Dillon elaborated that walnuts are also a good choice for sleep because they contain high amounts of omega-3 fatty acids. These healthy fats have not only been shown to improve heart health and protect against certain cancers, but also to aid the body in sleeping better and longer (via The Sleep Doctor). This is because omega-3s have anti-inflammatory properties and can help decrease levels of a stress hormone called norepinephrine, which disrupts REM sleep. “The standard American diet contains a greater prevalence of pro-inflammatory foods,” Dillon said, adding that consuming foods rich in omega-3s can “balance the inflammation in our body, which may in turn improve our sleep quality.”

Omega-3 fatty acids, along with magnesium, can also help stimulate melatonin production, meaning walnuts pack a double-punch when it comes to this important sleep hormone. “One study found that low levels of the omega-3 fatty acid, DHA, are linked with lower levels of melatonin. Increasing the consumption of omega-3 fatty acids in those with low serum DHA may increase melatonin production, which is essential for restful sleep,” Dillon explained to Mashed.

Some foods can disrupt sleep quality

Though walnuts are a great snack choice for those looking to improve their sleep, other nutritious foods can have the opposite effect. Dillon warns against pre-bedtime consumption of snacks that contain tyramine, an amino acid that is commonly found in pickled and fermented foods like sauerkraut. Although these items are full of beneficial probiotics, which aid in digestion, they also stimulate the sympathetic nervous system. While the parasympathetic nervous system is responsible for slowing the body down, the sympathetic nervous system revs up the body’s rapid involuntary response, or “fight or flight,” per Live Science. This speeds up the heart rate and makes the body feel alert and awake — not exactly a good recipe for drifting off to a restful sleep.

Of course, many of us already know that any food or beverages that contain caffeine can keep us awake at night. Dillon said that though caffeinated teas have helpful antioxidants, their caffeine content may cause us to “spend an extended amount of time in the ‘REM cycle’ stage of sleep, too much of which can make us feel groggy the next day.” If you’re peckish before bed, put down the kombucha and caffeinated tea in favor of walnuts.source

1. Maintain a constant daily schedule

Picking a set “bedtime” and wake-up time can help normalize your rest routine for your body. Be patient with yourself, as it will likely take some time to change your sleep schedule, but stick with it. It’s important to avoid hitting the snooze button, no matter how tempting. Even if it feels nice in the moment, that extra nap isn’t high quality and will likely just throw off your schedule and make you feel sluggish throughout the morning.

One solution for how to get better sleep is to maintain a consistent sleep schedule throughout the week. If you’re the kind of person who likes to stretch your sleep budget thin during the week, then catch up on the weekends, it’s probably bad news for your overall sleep quality.

However, your sleep quality can be greatly improved by keeping a consistent schedule.

Yes, this might mean going to bed a little earlier on weeknights and waking up a little earlier on weekends, but getting your body’s internal clock properly aligned in this way can have major long term benefits.

In fact, studies have shown that erratic sleep schedules can lead to a higher risk of:¹

• Obesity
• Depression
• Other disorders

How To Adjust Your Sleep Schedule

Whether you’re starting a new job, readjusting after traveling to a different time zone, or just trying to break an unhealthy pattern, it can be a challenge to adjust your sleep schedule.

Fortunately, we have some tips for that, too:

• Take it slow. Unlike turning back the clocks (a common cause of disrupted sleep), you don’t have to adjust your sleep schedule all at once. Tweak your bedtime and wake-up time by 15 minutes every day until they’re where you want them.
• Avoid naps. Look, everyone loves a good nap. But if you’re having trouble sleeping, dozing off during the day will only exacerbate the problem. Skip the siestas until your sleep schedule is squared away.
• Become a creature of darkness. We’re going to talk more about creating a relaxing bedtime environment below, but in short, your body doesn’t know it’s time to sleep if you keep shining light in your eyes.
• Then, open those curtains. When it comes to waking up, natural sunlight is what tells our body it’s time to get going. Whenever possible, get some sun on that skin as quickly as possible after your alarm goes off.

2. Reduce caffeine intake

Caffeine will take up to 12 hours to completely leave your system. This means that even if you are able to fall asleep at a decent hour with coffee in your system, the quality of your sleep may be severely reduced. Consider only drinking caffeinated beverages in the morning or switching to options with considerably lower amounts of caffeine, like decaf coffees or teas.

3. Turn off the computer or television

In addition to intellectual distractions that may get your thoughts and anxiety going, bright lights from your computer or television will stimulate your brain when it is trying to naturally wind down in the evening. We’d recommend avoiding all electronics at least an hour before you intend to head to bed.

Are you in bed right now searching for tips on how to get a good night’s  sleep? First of all, you’re busted! Second, you’re going to need to set aside your phone if you really want to sleep better.

Our sleep-wake cycle (also known as our circadian rhythm) is regulated by the production of the hormone melatonin. Studies have shown that the blue light emitted by cell phones restricts the production of melatonin.² This means that staring at your phone in bed can literally convince your brain that it isn’t nighttime at all.

(And we’re not even going to get into the agitation or anxiety that can come from scrolling work emails or social media right before trying to sleep.)

To improve your sleep quality, try to stop using screens at least 30 minutes before bed. You might also try these sleep expert activities to help your brain relax:

• Read a book (the paper kind)
• Write in a journal or make a to-do list
• Take a shower or bath
• Meditate or listen to relaxing music

4. Don’t go to bed on a full stomach

Related to the importance of your sleep schedule, it’s important that you try to eat dinner around the same time to keep your body on a regular overall schedule. If you’re really having cravings, stick to small snacks and avoid sugar, alcohol, and nicotine.

Cut Out Midnight Snacks

One activity that isn’t going to help you get better sleep is eating. Admittedly, we’ve all crept into the kitchen late at night to get something to munch on. But, if you’re having difficulty falling asleep, you may need to act like a gremlin, and stop eating after midnight (or well before).

Eating late and then lying down to go to sleep can cause heartburn or acid reflux, leaving you tossing and turning uncomfortably. Furthermore, if you’ve got a sweet tooth, your sugar high or caffeine intake might contribute to your insomnia.

Rather than having a late night snack, consider sipping on a cup of soothing, decaffeinated tea, such as chamomile or lavender tea. And if you do have to have a bedtime snack, consider these healthy late night snacks  that will curve your cravings and mitigate your sleep disruption.

5. Don’t go to bed on an empty stomach

At the same time, it doesn’t help to try and sleep when your stomach is growling. If your mind and body are distracted by how hungry you are, it is going to be much more difficult for you to put either at ease as you try to calm yourself for a restful night of sleep.

6. Engage in regular exercise

Exercise can actually help improve both the quality and quantity of sleep you get each nice. You will spend more time in deep sleep cycles if you’ve exercised during your day and will likely feel tired enough to fall asleep more easily. Squeezing in a workout can also help reduce anxiety and stress that normally disrupts your sleep practice.

Exercise, But Not Too Late

Studies have shown that staying active during the day and regularly exercising can lead to better sleep at night. But, there’s a cut-off point.

If you’re an evening exerciser, you’ll want to make sure that your workout is wrapped up at least an hour before you plan to sleep. Why?

Because exercising raises your heart rate and body temperature, it can be harder to get to quality sleep afterwards. You need a proper cool-down before getting into bed.

7. Limit beverage consumption before bed

Like we stated when it comes to eating before bed, it’s best to avoid drinking near your target bedtime. This will help reduce or eliminate any necessary trips to the bathroom that will disrupt your sleeping cycle.

8. Keep your bedroom dark & quiet

Lights can naturally trick your body into thinking you should be awake, so it’s best to reduce outdoor light pollution and limit any indoor lighting in the evening as you prepare for sleep. Any efforts to reduce noise in your bedroom can also go a long way in improving the quality and quantity of your sleep.

9. Invest in a comfortable mattress, pillow & bedding

Having the wrong tools can throw off your entire practice for any endeavor, especially when it comes to building a healthy sleep practice. An investment in your mattress, pillow, and bedding is an investment not only in your quality of sleep but your overall quality of health and life. If you have questions about what the best choices are for your specific needs, you can always reach out to our sleep apnea dentists in Manahawkin.

10. Go to sleep and wake up using your internal alarm clock.

We mentioned the importance of avoiding the snooze button earlier, but the best possible practice is to actually avoid using an external alarm clock altogether.

Get Uninterrupted REM Sleep

REM sleep is the deepest part of our sleepy time cycle. This deeps sleep begins around 90 minutes after we’ve fallen asleep. Getting a healthy amount of uninterrupted REM sleep has been shown to be critically important for a number of reasons:³

• REM sleep improves cognitive function and memory
• A lack of REM sleep can diminish your immune system
• Missing out on REM sleep may cause you to be less alert the next day
• Low levels of REM sleep can make pain hurt more

However, if you’re a light sleeper, getting uninterrupted REM sleep can be easier said than done. To ensure nothing disturbs your slumber, you might try:

• Putting your cell phone on silent to avoid unnecessary notifications
• Wearing an eye mask and/or ear plugs to block out light and sound
• Upgrading to blackout curtains and/or trying out a white noise machine
• Forcing your snoring partner to sleep on the couch (as a last resort, of course)

How Much Sleep Should You Be Getting?

Now that you know our tips on how to sleep better, how much sleep do you really need? Experts break down the recommended hours of sleep like this:⁴

• Teens (Ages 14 to 17) – 8 to 10 hours
• Young Adults and Adults (Ages 18 to 64) – 7 to 9 hours
• Older Adults (65+) – 7 to 8 hours

(We skipped over children and younger age groups because they probably aren’t reading this. And, honestly, we’re a little jealous that experts recommend they sleep for ten hours per day.)

While these are the recommended ranges for each age group, there are also what’s known as “acceptable” amounts of sleep that expand the spread for each cohort. For instance, until age 25, it’s normal to need up to 11 hours of sleep. Whereas by the time you’ve hit 65, you may feel fully rested on only five hours of sleep per night.

Essentially, everyone’s a little different. While consulting a chart can be helpful, your own sleep needs are going to be unique to you.

How Do I Know If I’m Getting Enough Sleep?

The hours of sleep you need depend a lot on how active you are and your overall health. To assess if you’re getting the optimal amount of sleep, consider the following questions:

• Do you feel grumpy and unproductive throughout your day?
• Do you need to regularly consume coffee or other forms of caffeine to keep going?

If you answered yes to either of these questions, then you’re probably skipping out on restful sleep.

A good way to test this—especially for those of you with a strict wake-up time—is to see how long you sleep on a day off when there’s no alarm to rouse you. That’s not just your body recovering from a tough week; it’s your body telling you how much deep sleep you naturally require.

You might also consider keeping a sleep journal or using a fitness tracker to log how many hours of restful sleep you’re getting. If you’re still struggling to suss out your snoozing statistics, you can consider participating in a sleep study.

Ask Yourself, Is It You Or Your Bed?

You’re sticking to a disciplined sleep schedule, cutting down on screen time, and are active everyday. And yet, when night comes, you’re still tossing and turning. Maybe the problem isn’t you at all.

Some signs you might need a new mattress include:

• Difficulty finding a comfortable position because of poking springs or sagging support
• Feeling jostled or disturbed every time your partner moves around
• Sneezing or itchy eyes caused by a build-up of allergens

Your pillows and sheets can also have a significant impact on your sleep quality.

• Feeling hot during the night? Consider switching to a more breathable sheet or investing in a cooling mattress, like the Wave Hybrid Snow Mattress which features advanced cooling technology that can prevent overheating for over 12 hours.
• Waking up with a stiff neck? You might need to find a pillow that better suits your sleeping position, like a Low Loft Pillow or a Body Pillow.

Your All-day Guide to a Perfect Night’s Sleep

Getting the rest you need isn’t just about bedtime – you’ve got to play the long game. Just make these easy zzz-friendly tweaks to your daily routines and you’ll be snoozing like a koala in no time.

Many people think about sleep about twice a day: at night when they’re tired and need to go to
bed, and in the morning when they’re still tired and want to stay there. But lack of shut-eye affects your whole day. Poor sleepers miss out on immune and emotional regulation as well as tissue restoration and repair, says sleep research psychologist Dr Jessica Payne. Stress may keep you awake, but insomnia can impair your ability to regulate tension the next day, creating a “sleep-stress snowball”, she says.

Stress also increases levels of neurotransmitters and hormones, such as cortisol and norepinephrine, keeping you in a hyper vigilant state, always watchful for tigers (or work enemies). “The more you’re stressed, the poorer your sleep is and the worse your stress is,” Dr Payne says.

Given sleep’s ability to wreak havoc on your waking hours, it only makes sense that your days might be causing you trouble at night. Think of your day like a fitness class, says sleep researcher and neurologist Dr Christopher Winter, author of The Sleep Solution: Why Your Sleep Is Broken and How to Fix It. Your decision-making brain is like a good instructor who leads you through the class, giving notice of what’s coming up next or how many burpees you’ll be doing. Without that sort of guidance, your body holds back, he says, trying to conserve energy to prepare for the unknown.

It boils down to this: A good night’s sleep relies on healthy daytime activities to regulate your internal clock, or circadian rhythm. “The interplay of sleep and rest, when it’s on a schedule, helps signal your brain as to where it is within a 24-hour circadian cycle,” explains Dr Winter. Certain activities send the right signals and others can be harmful, adds neurologist Dr Donn Dexter.

Here’s your 24-hour guide to which is which so you can snooze better, starting tonight. 

MORNING

Quit hitting snooze

Your greatest sleep mistakes happen in the morning, Dr Winter says. After a bad night, it’s tempting to give yourself a pity pass to sleep in or take a sick day. On the other hand, a regimented response at the start of the day helps set your brain’s sleep-wake clock. The exception: If you wake up too early, don’t try to force a return to sleep – it’s smarter to go ahead and get up. That reduces the chance of developing a chronic case of insomnia, according to a US study.

Eat breakfast – even if you aren’t super hungry

Banking kilojoules for dinner leads to overeating in the evening, and then a night of fitful sleep as you try to digest that heavy meal. In the morning, be sure to eat some protein, such as eggs, meat, yoghurt or milk. “Protein tends to facilitate the production of dopamine, a wakefulness neurotransmitter,” says Dr Winter. Bonus: dopamine allows you to feel pleasure and satisfaction.

Step outside early

Exposure to morning daylight, preferably combined with exercise, such as walking the dog or to the bus stop, supports regulation of your internal clock, as the sun suppresses melatonin. Even on a cloudy day, a 10- to 30-minute outdoor stroll provides more light than being indoors with all the lights on. If you can do a heart pumping workout, even better. That’ll increase the serotonin that enhances mood and wakefulness and informs your internal clock, Dr Winter says

AFTERNOON

Find 10 mins of downtime

Your temperature naturally drops in the early afternoon, aligned with circadian rhythms, causing sleepiness. A short catnap during your lunch break at the same time each day can reboot energy levels, but it isn’t necessary to fall asleep. “Resting isn’t a failed nap,” Dr Winter says. The goal is to practise relaxation techniques that’ll be useful later at night. Allow your mind to wander and get drowsy for about 10 minutes, then get back to what you were doing, refreshed. Tip: Reading a book in a warm, cosy spot will make your eyes nice and heavy.

Don’t chug coffee

Your body produces adenosine, a molecule that serves as the ‘energy currency’ for the body and also promotes sleepiness, says Dr Mathew. As a stimulant, caffeine blocks adenosine and inhibits your brain’s natural increase in sleepiness as you move toward nighttime. Herbal tea or water is better in the afternoon. Plus, if you drink water throughout the day, you’ll need less in the evening, helping you to avoid those 3am bathroom trips.

Work out in the daytime

Exercising raises body temperature and levels of epinephrine and adrenaline, known sleep fighters. So, work out only during daylight hours to give time for heat and hormones to quiet down. “A falling body temperature almost acts like a signal that brings on sleep,” Dr Mathew says.

Do a short meditation

Decreasing daytime anxiety and worry can help you doze more deeply at night. Find five to 10 minutes to use the ‘body scan’ meditation technique, observing your body’s sensations, moving slowly from toes to scalp (or the reverse). Melt away stress either on your own or using a
guided meditation in an app or on YouTube.

EVENING

Write down what’s bugging you

Dr Payne says that when you don’t offload the day’s events, your brain continues to process stressful situations throughout the night. So, by writing down any problems beforehand, you can improve compartmentalisation and save figuring out the solutions for the morning. If you’re lying in bed stressing about sleep itself, get up and do something quiet for 15 minutes, such as reading or sketching in a low-lit room – steer clear of bright screens. “Some people treat the bed like a bus stop,” Dr Winter says, and obsess over missing the sleep bus. Adjust your expectations and start again tomorrow.

Create a ritual

Any kind of stimulus is problematic – even mindless Netflix reruns. You’ll experience subtle increases in blood pressure, heart rate and sweating. Instead, take at least 20 minutes to dial it down. Try gentle stretching, meditating or taking a bath. Think of it as a ‘bookmark’ at day’s end, Dr Payne says, telling the body and brain it’s okay to sleep.

Turn off the ceiling lights

Exposure to bright blue light can reduce melatonin levels by up to 50 per cent, says Dr Satchin Panda, author of The Circadian Code. And it’s not just your phone that’s to blame. Cool-hued ceiling lights also produce blue light. So, after dinner, switch to table lamps and fl oor lamps with warm- or orange-hued light bulbs. Electronic devices should also be set to night mode to warm the screen colour.

Stop eating at least two hours before bed

And also keep dinner on the lighter side. Your body’s digestive and waste functions need rest and downtime and to learn when “the kitchen is closed”, Dr Panda says, to prevent midnight snacking.

Are you getting enough sleep?

There’s a difference between time in bed and optimal shut-eye. The ideal sleep amount is between seven and eight hours, but to pull that off, you need to slide between the sheets at least eight hours before the alarm sounds. That way, you’ll have unhurried time to fall asleep and accommodate unplanned night waking. It’s normal to wake up during the night or toss and
turn a bit, but taking more than 30 minutes to fall back asleep is known as ‘sleep maintenance
insomnia’. If you’re having issues with night waking, try avoiding naps altogether during the day, suggests sleep expert Dr Reeba Mathew.

Could it be serious?

When patients visit Dr Mathew with sleep-related problems, she first rules out an undiagnosed sleep disorder, such as sleep apnoea, sleep-related low oxygen or restless legs syndrome.
Patients with untreated apnoea, for example, have an increased risk of blood pressure-related and cardiac problems, including heart failure, she says. A vicious cycle between untreated apnoea and early heart disease can ensue and, in severe cases, lead to risk of heart attack. Seek your doctor’s advice if you have been snoring, get plenty of sleep but still feel fatigued, or are otherwise concerned.

You may find yourself tossing and turning every night, wondering if there’s ever going to be a way for you to get a good night’s sleep. The solution may be as simple as “colorful” noises.

Before you buy that sound machine or download that white noise app, here’s a look at the different sounds and how they help you get a good night’s sleep.

Pink noise and white noise use the variation of high and low frequencies, which is associated with a peaceful rest throughout the night. But you may wonder:  Pink noise vs. white noise, what’s the difference?

Below we explain what pink noise and white noise are and how they are different. We also discuss other types of background noise people commonly use for sleep.

Can White, Pink, and Brown Noise Help You Sleep?

For some people, the grainy static sound you hear in white noise can improve sleep. It helps by masking the background noise and tuning it out. One recent study found that 38% of people fell asleep faster listening to white noise.

Pink noise reduces the difference between the background hum and loud, jarring noises that jolt you out of sleep, like a door slamming, a car horn honking, or someone snoring. So it may help you fall asleep faster and keep you in a deep sleep longer. You may also feel more rested when you wake up.

There isn’t much research yet on exactly how pink noise works and how well it helps you sleep. One study found that it lowered brain activity and led to more stable sleep. Another study found people who used it slept more deeply.

Studies are limited, but pink noise may also boost your memory. A recent study found that older adults who used it at night did better on memory tests the next day.

We need more research to find out how pink noise affects your sleep, focus, and memory. But it’s safe and has no downside, so you may want to try it to see if it helps you.

Pink, Brown, White, and Blue Noise: Definitions and Examples

Trying to decide which color noise is right for you can be tricky at first. It may take some time to realize which sound works best for you, whether it’s rustling leaves, thunder, or whirring fans.

With some knowledge and a little time, however, you’ll quickly find the best option for your sleep habits. Here’s what you need to know about pink noise vs. white noise and how they compare to other sonic hues used for sleeping.

What is Pink Noise?

Pink Noise is Used to Reduce Brain Waves

In this study, researchers found that those who listened to steady pink waves saw an increase in stable sleep. This is because pink noise may have the ability to reduce brain waves, which allows you to fall asleep faster. This color noise is a preferred method by many because it is deeper than white noise, but not as deep as brown.

Pink noise is a constant sound in the background. It filters out things that distract you, like people talking or cars going by, so they don’t interrupt your sleep. You may hear it called ambient noise.

Like white noise, it’s a steady background hum that may give you a better night’s sleep. But it uses deeper sounds and lower sound waves, so it may be gentler and more soothing. Basically, pink has a lower pitch than white noise.

Pink noise uses a consistent frequency, or pitch, to create a more even, flat sound, like a steady rain, wind rustling through trees, or waves on a beach. Its added depth and lower waves filter out higher sounds. As a result, you hear more relaxing, lower-frequency sounds.

With pink noise, lower frequencies are louder while higher frequencies are more diminished. This creates a soothing sound and is a great option for those who find white noise annoying and disruptive. Pink noise leans more toward environmental noise, so it’s no surprise most people prefer it.

In this study, a link was found between pink noise and deep sleep. This may be because pink noise is especially relaxing when used to drown out unwanted sounds and outside noises that could interfere with a person’s sleep.

Examples of Pink Noise:

• Rustling leaves
• Steady rain
• Ocean waves
• Heartbeats

Pink + Brown Noise Helps Tinnitus

According to Popular Science, those who suffer from tinnitus (constant ringing in ears) prefer pink or brown noise due to the lower frequencies. White noise can be aggravating to those with sensitive hearing because the high frequency sounds are more intense, making it harder for the person to fall asleep.

What is Brown Noise?

Brown Noise Promotes Concentration

Brown noise may help with getting a good night’s sleep, but it can also help with focus and concentration. Many people prefer listening to brown noise when studying or working to improve productivity and drown out any distractions. It can also help ease anxiety, especially in high-stress situations.

Brown noise, also called red noise, produces a rumbling sound that’s deeper with a bass-like tone than pink or white noise. The sound level (decibels) decreases as the frequency goes up more than it does in pink noise. It’s similar to a steady heavy rainfall or a shower with good pressure. Some sleep apps use this sound instead of pink noise to give it a deeper, grainier effect.

Studies show that brown noise might help lower symptoms if you have ringing in your ears. It’s also shown to improve your thinking skills. More research is needed to see if and how brown noise affects sleep.

Brown noise is deeper and stronger at the low end of the sound spectrum. Unlike pink and white noise, it doesn’t contain any high-frequency sounds. Though not a common option for sound sleep, brown noise can help certain people with concentration. According to the CEO of Adaptive Sound Technologies, Inc, Sam Nicolino, brown noise “has more bass than white noise, making it more pleasant to listen to.”

Examples of Brown Noise:

• Low roaring
• Strong waterfalls
• Thunder

What is White Noise?

 White Noise Benefits Include Masking Sounds 

Many people find success in sleeping when listening to white noise because it drowns out unwanted sounds. Smaller environmental sounds around you can distract you from getting a good night’s rest. However, when using a white noise machine, any noises that happen are drowned out by the noise you’re already hearing.

White noise is equally spread across the sound spectrum, representing all audible frequencies at the same intensity. Because of that, many people find it hard to listen to when falling asleep because they get startled hearing high-pitched noises or heavy bass sounds.  So, how does white noise help you sleep? According to this study, others find these frequencies relaxing because they block out distracting and unwanted sounds.

You can imagine white noise as similar to white light. When every color on the spectrum is bright, it becomes white light — similarly, white noise includes all frequencies at the same intensity.

Examples of White Noise:

• Whirring fan
• Radio or television static
• Vacuum
• Humming air conditioner

What Are the Other Colors of Noise?

Black noise: This type of noise uses pure silence with sudden occurrences of noise. The dominant energy level is zero throughout all frequencies with bits of random noise and occasional rises. In Black noise, there is complete silence with bits of random noise. Some people need this type of silence to get quality sleep.

Red noise: This is another name for brown noise. The two mean the same exact thing: deep sounds at the low end of the spectrum with minimal high-frequency sounds.

Red noise is another name for brown noise. The two mean the same: deep sounds at the low end of the spectrum with minimal high-frequency sounds.

Brown noise is much deeper than pink and white noise and has higher energy at a lower frequency. As a result, it induces sleep and relaxation.

Blue Noise: Blue noise contains all the audible frequencies, but the higher-pitched frequencies are amplified. Because of this, blue noise can sound harsh to some people and isn’t widely used for sleep support. An example of this type of noise would be a hissing hose. Blue noise can sound irritating to many people as its frequencies are higher-pitched. Thus, it can’t support quality sleep. Its power increases as the frequency goes up. Blue noise sounds slightly shriller than pink and white noise. Imagine the hissing noise you hear when a water spray is turned on.

Violet noise. Also called purple noise, it’s the opposite of brown noise. The volume goes up when the frequency does and it gains power faster than blue noise. It’s one of the higher-pitched color noises. It’s often used to treat tinnitus, a condition that causes loud ringing in one or both ears.

Grey noise. This produces noise at higher and lower frequencies but not so much in the middle frequencies. It’s similar to white noise, but more balanced.

Tips to Bolster the Effects of Color Noise

Though utilizing color noises in your bedtime routine can help you get a good night’s sleep, there’s still a variety of factors you should consider before hitting the hay to ensure your body and mind are in a relaxed state.

Check out our tips below:

1. Turn Off Bright Lights

Scrolling through your smartphone or watching TV before bedtime suppresses melatonin, making it hard for you to go to sleep. Avoid bright lights from screens or lamps at least an hour before you go to bed. If you’re looking for a soothing night light option, a glow light can give your bedroom a soft glow that dims as you fall asleep.

2. Exercise Regularly

Implementing a consistent exercise routine during the day may help promote a better night’s sleep. Since exercising exerts physical and mental energy, you’ll notice yourself feeling more tired at night.

3. Establish a Sleep Schedule

Making sure you wake up and go to bed at the same time every day is important, otherwise you’ll find yourself feeling sleep deprived. Set an alarm every morning and go to bed at the same time every night — it’ll make a big difference in your sleep quality. Check out our sleep calculator to figure out how much sleep you need.

4. Limit Food Intake Before Bed

Eating large meals before sleep can inhibit sleep quality and cause the body’s metabolism to slow down. Research shows, however, that eating small, nutritious snacks like fruit or toast before bed can actually be beneficial and combats hunger with little negative effect.

5. Avoid Stimulants At Night

Avoid drinking caffeine before bedtime. Doing so may result in restless nights and lack of sleep, so be sure to limit your caffeine intake to morning or midday. If you find yourself experiencing a caffeine crash during the day, it’s best to avoid drinking it entirely. Alcohol also reduces your quality of sleep by disrupting your circadian rhythm.

6. Limit Naps 

Napping during the day can disrupt your sleep schedule and make it harder for you to get some shut eye. According to the National Sleep Foundation, napping for 20 minutes or less is the most effective way to feel refreshed and still be able to go to bed.

Still unable to get some much-needed rest? You might want to invest in higher quality sheets and pillows, or maybe even a glow light. With the right bedding and color noise, you’ll be nodding off in no time. source

The Importance of Sleep with Alzheimer’s

The brain is programmed to “clean mode” at night that washes away waste products. Poor sleep could make this cycle less effective and leave Alzheimer’s toxins to build up.

Study findings: Researchers studied the brain of 13 participants asleep and awake. They discovered that, during deep sleep, the brain is washed by coordinated waves of cerebrospinal fluid which can remove waste products. The authors noted that these waves are not as strong in people with memory impairment, and chronic sleep problems can lead to the accumulation of beta-amyloid, a protein linked to Alzheimer’s disease.

Why it matters: Alzheimer’s disease is the main form of dementia, and the number of people diagnosed with dementia is expected to grow by 204% worldwide by 2050. Understanding the role that sleep can play in healing the brain, and how it can be disrupted, are critical in the search for a cure and preventive measures.

The final word: The study’s findings reveal the synchrony of processes that enable waste clearance, and suggest how this may, in the future, help to explain what role sleep quality plays in Alzheimer’s disease. The authors recommend more probing studies to identify what may influence these nocturnal cleaning “rhythms”.

Sleep: the brain’s housekeeper

Sleep flicks the switch that allows the brain to go about maintenance work without being interrupted by the pesky activity of a conscious mind.

There are several stages and depths of sleep, and you cycle through them several times per night. When you start to nod off, you are at stage 1 of non-rapid eye movement (nREM) sleep. Once you sink a bit deeper, you’re into nREM stage 2, during which your body temperature drops and your heart rate starts to slow.

Stage 3 of nREM is one we’ll discuss in this article. It is the deepest sleep: your blood pressure drops, your muscles relax, and your breathing is slowed. And this is the time your brain has set aside to clear out the waste. It’s followed by rapid-eye movement (REM) sleep when you dream, your eyes flick around, and your brain is more active. Then it all starts again.

Deep sleep, deep clean

For many centuries, the brain had the scientific community stumped because they couldn’t figure out how it got rid of metabolic waste.

The central nervous system, which includes the brain, doesn’t have a lymphatic system like the rest of the body. Scientists found this very curious because this system is responsible for removing waste products and toxins from the body. In fact, for many centuries, it was believed that the central nervous system of mammals was simply devoid of lymphatic activity.

The idea of getting a cerebral spa treatment every night is appealing

However, that left an important question unanswered: how on earth does the brain rid itself of rubbish? Thanks to new technologies and determined scientists, we now know that the brain has its own way of doing things. Firstly, it does have lymphatic vessels, and they can be seen on a correctly tuned magnetic resonance imaging (MRI) scan.

But that’s not all, as this paper helpfully reminds us. The brain is much classier than initially thought: it repeatedly rinses itself in cerebrospinal fluid (CSF) every night. Your brain and spinal cord bathe in this clear, colourless fluid all day, and at night, waves of it surge over the brain and clear it of metabolic waste.

It takes three baby

Three synchronised actions allow the brain to clear out the byproducts of metabolism and other waste products that accumulate each day.

A team of seven researchers, led by Nina E. Fultz, looked for the missing piece of a messy puzzle that included brain waves, blood, and cerebrospinal fluid. It was already known that our thinking organ emits brain waves (tiny electrical pulses) that make our neurons fire in a specific region. The same goes for CSF — scientists already knew that it could remove metabolic waste products.

Yet, it was unclear whether these processes are related, and if so, what is their purpose. Fortunately, these intrepid scientists intervened to solve this nail-biting enigma. They put 13 slumbering (and sometimes, waking) people through their paces with new and old technology.

That cat is rolling in Delta waves

They attached electrodes to their subjects’ heads, measuring electric impulses on the outer layers of the brain (the cortex), a non-invasive technique called electroencephalography (EEG). Participants also underwent functional MRI scans that could show changes in cerebrospinal fluid and blood flow.

When the scans were in, the team compared the timing and effect of these three parameters and concluded that these features are synchronised. So, in order for the brain “washing” to function, it requires three steps. A slow brain wave breaks across a network of neurons, which triggers an increase in CSF and a decrease in blood flow (which probably makes room for the cerebrospinal fluid to wash over the brain).

What’s it got to do with Alzheimer’s?

There are brain waves for each level of cerebral activity, and they can be disturbed in patients with specific diseases.

Brain waves coordinate levels of activity in this organ, so it should come as no surprise that they can be disturbed in different diseases. People with Alzheimer’s have fewer and smaller Delta waves, the long slow waves that occur during deep sleep (nREM stage 3), and this research may help understand why.

Poor sleep quality is an important feature of Alzheimer’s, but it could be poor sleep quality and thus fewer, weaker Delta waves during a person’s lifetime that might influence clinically significant aspects, like the accumulation of specific proteins associated with this disease.

There are two proteins in the brain that were identified in the pathology of Alzheimer’s: beta-amyloid, which accumulates in plaques, and tau, a protein that is found in cerebrospinal fluid. Other studies have shown that wakefulness can increase levels of tau protein and that chronic sleep deprivation can increase beta-amyloid plaque accumulation.

Read the study here

This study postulates that disturbances in this nocturnal process of brain “cleaning” may explain why these proteins accumulate in the brain. By demonstrating that three separate actions are required for effective removal of metabolic waste during deep sleep, they suggest it might be the first step to uncovering how disturbances in this harmonious process may allow these proteins to accumulate in the first place.

TIPThe Atlas DNA Test checks for Alzheimer’s disease risks and recommends a full night’s sleep (7-9 hours) as a preventive measure.

​​What are circadian rhythms?

Circadian rhythms are physical, mental, and behavioral changes that follow a 24-hour cycle. These natural processes respond primarily to light and dark and affect most living things, including animals, plants, and microbes. Chronobiology is the study of circadian rhythms. One example of a light-related circadian rhythm is sleeping at night and being awake during the day. The Average Teen Circadian Cycle image shows the circadian rhythm cycle of a typical teen.

What are biological clocks?

Biological clocks are organisms’ natural timing devices, regulating the cycle of circadian rhythms. They’re composed of specific molecules (proteins) that interact with cells throughout the body. Nearly every tissue and organ contains biological clocks. Researchers have identified similar genes in people, fruit flies, mice, plants, fungi, and several other organisms that make the clocks’ molecular components.

What is the master clock?

A master clock in the brain coordinates all the biological clocks in a living thing, keeping the clocks in sync. In vertebrate animals, including humans, the master clock is a group of about 20,000 nerve cells (neurons) that form a structure called the suprachiasmatic nucleus, or SCN. The SCN is in a part of the brain called the hypothalamus and receives direct input from the eyes.

 

How do circadian rhythms affect health?

Circadian rhythms can influence important functions in our bodies, such as:

• Hormone release
• Eating habits and digestion
• Body temperature

However, most people notice the effect of circadian rhythms on their sleep patterns. The SCN controls the production of melatonin, a hormone that makes you sleepy. It receives information about incoming light from the optic nerves, which relay information from the eyes to the brain. When there is less light—for example, at night—the SCN tells the brain to make more melatonin so you get drowsy.

Nobel Prize

In 2017, researchers Jeffrey C. Hall, Michael Rosbash, and Michael W. Young won the prestigious Nobel Prize for their circadian rhythms research. By studying fruit flies, which have a very similar genetic makeup to humans, they isolated a gene that helps control the body’s clock. The scientists showed that the gene produces a protein that builds up in cells overnight, then breaks down during the day. This process can affect when you sleep, how sharply your brain functions, and more. All three researchers were funded by NIGMS when these major discoveries were made.

 

 

What factors can change circadian rhythms?

Changes in our body and environmental factors can cause our circadian rhythms and the natural light-dark cycle to be out of sync. For example:

• Mutations or changes in certain genes can affect our biological clocks.
• Jet lag or shift work causes changes in the light-dark cycle.
• Light from electronic devices at night can confuse our biological clocks.

These changes can cause sleep disorders, and may lead to other chronic health conditions, such as obesity, diabetes, depression, bipolar disorder, and seasonal affective disorder.

How are circadian rhythms related to jet lag?

When you pass through different time zones, your biological clock will be different from the local time. For example, if you fly east from California to New York, you “lose” 3 hours. When you wake up at 7:00 a.m. on the East Coast, your biological clock is still running on West Coast time, so you feel the way you might at 4:00 a.m. Your biological clock will reset, but it will do so at a different rate. It often takes a few days for your biological clock to align with a new time zone. Adjusting after “gaining” time may be slightly easier than after “losing” time because the brain adjusts differently in the two situations.

How do researchers study circadian rhythms?

Scientists learn about circadian rhythms by studying humans and by using organisms with similar biological clock genes, such as fruit flies and mice. Researchers doing these experiments control the subject’s environment by altering light and dark periods. Then they look for changes in gene activity or other molecular signals. Scientists also study organisms with irregular circadian rhythms to identify which genetic components of biological clocks may be broken.

Understanding what makes biological clocks tick may lead to treatments for jet lag, sleep disorders, obesity, mental health disorders, and other health problems. It can also improve ways for people to adjust to nighttime shift work. Learning more about the genes responsible for circadian rhythms will also help us understand more about the human body.

What Can Disrupt Circadian Rhythm?

Disruptions to circadian rhythm can occur over the short- or long-term. Experts have identified a number of types of circadian rhythm sleep-wake disorders (CRSWD) based on their characteristics and causes.

• Jet Lag Disorder: This occurs when a person crosses multiple time zones in a short period of time and gets its name from the fact that it is often experienced by people who take intercontinental flights. Until a person’s circadian rhythm can acclimate to the day-night cycle of their new location, they are likely to suffer sleeping problems and fatigue from jet lag.
• Shift Work Disorder: Work obligations can cause major disruptions in a person’s circadian rhythm. Shift work, which requires having to work through the night and sleep during the day, puts a person’s sleep schedule directly at odds with the local daylight hours.
• Advanced Sleep Phase Disorder: People with this type of disruption find that they get tired early in the evening and wake up very early in the morning. Even if they want to be up later at night or sleep later in the morning, people with an advanced sleep phase disorder usually cannot do so. This disorder is relatively rare, affecting around 1% of people in middle and older age Trusted SourceNational Library of Medicine, Biotech InformationThe National Center for Biotechnology Information advances science and health by providing access to biomedical and genomic information.pubmed.ncbi.nlm.nih.gov, and occurs more frequently in older adults. In some cases, advanced sleep phase disorder may be related to an inherited genetic cause.
• Delayed Sleep Phase Disorder: This type of circadian rhythm disruption is associated with “night owls” who stay up late at night and sleep in late in the morning. It is rare among the general population — affecting just 1 or 2 people out of every 1,000 — but impacts up to 16% of teens. The exact cause is unknown but may be related to genetics, underlying physical conditions, and a person’s behavior.
• Non-24 Hour Sleep Wake Disorder: This condition occurs primarily in people who are blind Trusted SourceNational Organization for Rare Disorders (NORD)NORD is a patient advocacy organization dedicated to individuals with rare diseases and the organizations that serve them.rarediseases.organd are not able to receive light-based cues for their circadian rhythm. Their body still follows a 24-hour cycle, but their sleeping hours constantly shift backward by minutes or hours at a time.
• Irregular Sleep-Wake Rhythm Disorder: People with this rare disorder have no consistent pattern to their sleep and may have many naps or short sleeping periods throughout a 24-hour day. It is frequently connected to conditions that affect the brain Trusted SourceNational Library of Medicine, Biotech InformationThe National Center for Biotechnology Information advances science and health by providing access to biomedical and genomic information.pubmed.ncbi.nlm.nih.gov, such as dementia or traumatic brain injury, that limit the proper functioning of the master clock in the hypothalamus.

As this list demonstrates, there are diverse causes of circadian rhythm disorders. Some circadian disruptions are related to individual behavior, such as for travel or work, that puts sleep schedules out of whack with normal daylight exposure. Other disorders stem from an underlying issue that causes an inability to receive or process environmental cues that regulate the body’s master clock. In certain situations, genetic causes may be involved, or the cause may remain unknown.

How To Maintain a Healthy Circadian Rhythm

While we don’t have full control over our circadian rhythm, there are healthy sleep tips that can be taken to try to better entrain our 24-hour sleep cycles.

• Seek out sun: Exposure to natural light, especially early in the day, helps reinforce the strongest circadian cue.
• Follow a consistent sleep schedule: Varying your bedtime or morning wake-up time can hinder your body’s ability to adjust to a stable circadian rhythm.
• Get daily exercise: Activity during the day can support your internal clock and help make it easier to fall asleep at night.
• Avoid caffeine: Stimulants like caffeine can keep you awake and throw off the natural balance between sleep and wakefulness. Everyone is different, but if you’re having trouble sleeping, you should avoid caffeine after noon.
• Limit light before bed: Artificial light exposure at night can interfere with circadian rhythm. Experts advise dimming the lights and putting down electronic devices in the lead-up to bedtime and keeping electronics out of the bedroom and away from your mattress.
• Keep naps short and early in the afternoon: Late and long naps can push back your bedtime and throw your sleep schedule off-kilter.

These steps to improve sleep hygiene can be an important part of supporting a healthy circadian rhythm, but other steps may be necessary depending on the situation. If you have persistent or severe sleeping problems, daytime drowsiness, and/or a problematic sleep schedule, it’s important to talk with a doctor who can best diagnose the cause and offer the most appropriate treatment.

Circadian Rhythm: What Is It And How To Reset Your Body Clock?

Humans have clock genes that make the body tick like a well-oiled machine. Learn about your circadian rhythm and how it affects your health and disease risks.

 

A circadian rhythm is a 24-hour biological clock that affects your sleep, digestion, and metabolism. When your circadian rhythm is disrupted, it can even increase your disease risks.

The circadian rhythm is a body clock that organises all the biological processes necessary for life. It is dictated by clock genes that trigger essential metabolic activities, like storing energy, transporting oxygen, getting rid of waste, and releasing hormones and neurotransmitters.

Even though you can’t see or feel this clock, circadian health is essential for your health and wellbeing. In this article, you’ll discover what happens when the cycle rhythm is disrupted, how to reset your body clock, and how to fix your sleep schedule.

What is a circadian rhythm?

 

The circadian rhythm is a 24-hour clock that dictates millions of invisible metabolic processes that keep the body alive. It determines digestive rhythms, fat burning and fat storage, sleeping patterns, and much more. This biological rhythm is run by clock genes that signal when each process should take place.

Approximately 20% of genes turn on and off during the 24-hour cycle.

Going to bed late, playing with your phone at midnight, eating late in the evening, and working night shifts are all factors that can shift your circadian cycle. Scientific evidence now indicates that circadian rhythm disruptions are associated with serious, but preventable, chronic diseases like diabetes type II, heart disease, obesity, stroke, and cancers.

How the circadian cycle works

 

The circadian rhythm is made up of a set of clocks and a central “master clock”, called the suprachiasmatic nucleus (SCN). The SCN is located in the hypothalamus, the part of the brain responsible for regulating stress, reproduction, and growth hormones. It also indirectly impacts sleep hormones.

The body’s clock contains about 20,000 cells, which are located just above the intersection of the optic nerves. The cycle rhythm is set by signals from special melanopsin cells in the retina in response to light exposure. Blue light (from bright daylight, phone screens, and TVs) has the strongest effect on melanopsin receptors, followed by green and red light.

The circadian rhythm reacts to light: it wakes you up, and it puts you to sleep by triggering cascades of chemical events in your brain.

Body clock genes have been discovered in nearly every organ of the human body. These genes turn on and off at predictable times, switching on and shutting down the production of proteins that perform essential functions within the body’s cells.

Sleep washes Alzheimer’s particles from the brain

 

Interestingly, studies show that blind mice and blind people still have active melanopsin receptors that regulate their biological clock. This helps to explain why patients suffering from blindness can “sense” light, even if they can’t see it.

Do you need a body clock reset?

 

Sleeping at irregular times, using devices, eating late at night, and other pernicious habits displace the cycle rhythm. When a person’s biological cycle isn’t on schedule, it causes a wide range of minor health issues that can affect everyday life.

Low energy, mood swings, food cravings, weak immunity, and having trouble losing weight are common side effects of circadian disruption according to Professor Satchidananda Panda, author of the Circadian Code.

Area	Common problems
Sleep	Difficulty falling or staying asleep, sleeping too much
Weight	Weight gain, inability to lose weight
Vitality	Low energy, reliance on caffeinated products
Diet	Late-night food cravings, stomach cramps & indigestion
Mood	Depression, emotional outbursts & irrational anger
Immunity	Weak immune system, frequent illness & infections

Circadian rhythm and digestion

 

The digestive system secretes the most gastric juices, enzymes, and hormones in the first half of the day. This activity reduces as the afternoon progresses into evening. These molecules are all essential for healthy digestion, which is why eating late at night can cause indigestion.

Circadian rhythm and sleep

 

At night, the circadian rhythm is focused on putting the body to sleep, removing waste products, and repairing tissues from the wear-and-tear of daytime activities. In fact, sleep is the only time for the brain to remove the waste products of chemical reactions.

When you mess with your sleep schedule, or deprive yourself of sleep, you impair the brain’s ability to operate at maximum efficiency.

Circadian rhythm and disease

 

Living out of sync with the body’s circadian rhythm over the short and long term is associated with serious, chronic, and preventable diseases that affect the body’s metabolism, according to a 2016 systematic review on the “Interaction between circadian rhythms and stress”.

In one referenced study, the human participants with impaired circadian rhythm function had “higher blood glucose and insulin levels as well as elevated blood pressure, which are markers for metabolic and cardiovascular disease.”

The study’s summary of its effects on night shift workers demonstrated that such professionals have “a higher incidence of obesity, diabetes type II and related metabolic disturbances along with hypertension (high blood pressure), coronary heart disease, and ischemic stroke”.

How to fix your sleep schedule

 

Light and darkness are the main determinants in circadian rhythm. When daylight or screen light is detected by your eyes, it sends signals to the suprachiasmatic nucleus, which regulates all the clock genes in your body.

To reset your body clock, you need to put yourself on a schedule that respects your body’s metabolic rhythm. While this may be impossible for night shift workers, it is an achievable goal for people with day jobs.

• Go to bed and get up at the same time every day.
• Turn off TV screens, phones, and tablets 1-2 hours before bed.
• Eat your biggest meal early in the day when digestive juices are highest.
• Stay away from caffeinated beverages in the afternoon and evening.
• Cut down on alcohol at night because it affects sleep quality.
• Stop eating at least 3 hours before bed to avoid indigestion.
• Get blackout curtains and dim light bulbs for your bedroom.
