    Importance of Sleep


    Sleeping allows the body to rest and repair itself. Research on how sleep affects the body has discovered the following:


    Sleep and Mortality Rates


    Studies indicate that getting too little and too much sleep can be hazardous to a person’s health. Individuals who reported sleeping more than 8 hours per night or less than 7 hours per night show a “modestly increased risk” of all-cause mortality, developing systematic diabetes, and cardiovascular disease. [1]


    Healthier Weight


    Individuals who get adequate rest tend to lose more fat when compared to those who were sleep-deprived. Those who did not receive adequate amounts of sleep tend to lose more muscle mass instead.


    Appetite and Sleep


    A lack of sleep blunts the functions and levels of the hormone’s leptin and ghrelin. These hormones, located in the hypothalamus, regulate feelings of hunger and fullness. In a recent study on sleep deprivation, individuals had an 18% reduction of leptin (an appetite suppressant hormone) and a 28% increase in ghrelin (which promotes feelings of hunger). In addition, researchers observed cravings for sweets, salty foods, and other high carbohydrate foods. [2]

    Inflammation


    Heart disease, arthritis, premature aging, stroke, and diabetes are all connected to inflammation. Sleep disturbances and sleep loss were associated with higher levels of C-reactive protein (CRP), an inflammatory protein where its levels are increased at sites of infection or inflammation. [3]


    Improved Memory


    Sleep can help memory retention. Memories go through the process of “consolidation,” where skills or memories are strengthened while sleeping. In addition, studies indicate a lack of sleep can impair memory consolidation and have a negative effect on both brain development and brain elasticity. [4]


    Sleep and Stress


    Stress has been known to disrupt sleep patterns, including both slow-wave sleep (SWS) and rapid eye movement (REM) sleep. REM is the 4th stage of sleep where dreaming occurs.  SWS is the physical restorative part of the sleep cycle where the body repairs itself and cells regenerate. Sleep disruptions during SWS  could limit the amount of healing the body does while sleeping.


    Tips on Getting Better Sleep Naturally


    Getting adequate rest is essential to good health. Here are some of the top ways to improve sleep quality naturally.


    Sunlight (Vitamin D)


    Getting sunlight helps to stimulate the production of two hormones: serotonin and melatonin.  Melatonin is believed to promote sleep by regulating the body’s biological clock and sleep-wake cycles. Serotonin helps improve focus, boost mood,  and maintain a sense of calm. Melatonin is produced in the evening and helps promote sleep. Studies indicate when exposed to sunlight or artificial light in the morning, melatonin production occurs sooner, helping a person sleep more easily at night. [5]


    Moderate Exercise


    Moderate exercise is defined as exercise that causes you to break out into a light sweat or are exercises that make it difficult to hold a long conversation. Long-term moderate exercise has been shown to provide significant improvements in sleep, quality of life, and mood in individuals with chronic insomnia. It was also shown to help relieve feelings of depression, tension, anxiety, and total mood disturbance. [6]

    In addition to traditional exercises such as walking, cycling, and swimming, many daily activities are considered moderate exercise:


    • Gardening
    • Raking leaves
    • Vacuuming
    • Pushing stroller
    • Washing/waxing car
    • Washing windows

    Lower Cortisol Levels

    Cortisol is the body’s main stress hormone. Produced in the adrenal gland, it regulates the following functions in the body:


    • Glucose metabolism
    • Immune release
    • Insulin release
    • Inflammatory response
    • Blood pressure regulation

    Cortisol has a daily rhythm: it is highest in the morning when waking up and gradually declines throughout the day. Under normal conditions, cortisol levels are lowest at bedtime when melatonin and adenosine production is increased. This allows for a more restful sleep.  High cortisol levels can cause fragmented sleep, which are sleep interruptions that can decrease the amount of deep, restorative sleep a person receives.

    Top ways to regulate cortisol levels include the following:


    • Moderate exercise
    • Reducing stress (yoga, meditation, hobbies, etc.)
    • Eating a balanced diet

    Diet and Sleep


    How we eat can also influence sleep quality. Studies indicate deficiencies in several nutrients could increase the risk of inadequate sleep.  A National Health and Nutrition Examination Survey found adults with short sleep (less than 7 hours nightly) were deficient in calcium, magnesium, and vitamin D. Women, in particular, had nutrient deficiencies in calcium, magnesium, and vitamins A, C, D, E, and K (above adequate intake). [7]

    Eating a balanced diet is critical for sleep quality. The following are considered the top foods to eat and avoid for sleep quality before bedtime.


    Best Foods to Eat Before Bedtime

    Worst Foods to Eat Before Bedtime

    Almonds

    Chocolate

    Cherries

    Potato chips

    Bananas

    Energy drinks

    Garlic

    Grapes

    Ice cream

    Oats

    Caffeine


    Avoiding Blue Light


    Blue light is the visible light ranging from 380 to 500 nm (nanometers). Sunlight is the primary source of blue light, but other forms of blue light include phone screens, computer screens, and fluorescent and LED lights.

    Before artificial blue light, the sun was the primary light source. Bodies were in tune with the natural light cycles and allowed the circadian rhythm to function normally. The artificial blue light used today could interfere with the production of melatonin, which could disrupt sleep patterns.

    Decreasing blue light exposure could be vital to avoiding sleep disruptions. Here are tips on protecting yourself from blue light at night:


    • Increase exposure to sunlight and bright light during the day. (This could increase the ability to sleep at night).
    • Reduce exposure to bright screens two to three hours before bedtime.
    • Consider using dim red lights for night lights.

    Nighttime Pre-Bedtime Sleep Tips


    Having a nightly ritual can help improve sleep quality. Here are the top things to do an hour before bedtime:


    • Take a warm bath
    • Read a book
    • Avoid caffeine and other foods (see list above)
    • Relaxation exercises (meditate, deep breathing, etc.)
    • Avoid physical (or psychologically) stressful activities
    • Go to bed at the same time every night
