Factors that influence your sleep-wake needs include medical conditions, medications, stress, sleep environment, and what you eat and drink. Perhaps the greatest influence is the exposure to light. Specialized cells in the retinas of your eyes process light and tell the brain whether it is day or night and can advance or delay our sleep-wake cycle. Exposure to light can make it difficult to fall asleep and return to sleep when awakened.
You may be doing all the right things—respecting your sleep needs and patterns, setting aside an ample amount of time to sleep, keeping a sleep diary—but still experiencing daytime sleepiness, fatigue, or insomnia. If that's the case, you should consider consulting a sleep specialist who can help you set up a better sleep environment, provide support for making behavioral changes that may be interfering with sleep, or possibly diagnose a sleep disorder. You have a right to feel well rested—and there are many resources available to help you get the sleep you need.
How magnesium works: Magnesium plays a widespread role in the human body, helping regulate and many essential functions. One of magnesium’s most important roles is to enable healthy enzyme function. Magnesium is involved in more than 300 different enzyme-related reactions in the body’s cells. This mineral helps regulate blood pressure, cholesterol and blood sugar, and helps to control the body’s stress response. Getting sufficient magnesium helps the body maintain healthy levels of GABA, a neurotransmitter that promotes sleep, as well as elevating and stabilizing mood.
What to do: I drink a tablespoon of tart cherry juice at night to help with sleep quality, especially on days with intense workouts since it also seems to help with muscle recovery and stiffness. Cherry juice can even be added to chamomile tea or other relaxing herbal teas (with the honey salt remedy above) to help improve the taste. I definitely recommend organic cherry juice if you can find it since it is concentrated and cherries are typically on the Dirty Dozen list.
Yoga relaxes your body and mind, making it perfectly primed for sleep. Rachel Salas, MD, associate professor of neurology at Johns Hopkins School of Medicine, suggests simple poses that allow you to focus on your breathing and releasing the tension of the day. Try sitting cross-legged and bending all the way forward, reaching your arms out straight in front of you with your head facing the ground. (Or ease into slumber with these 9 relaxing stretches you can do right in bed.)
Warming your body up with a hot shower an hour before bed and then stepping into cooler air will cause your body temperature to drop more precipitously. Studies show that this rapid temperature decrease slows your metabolism faster and prepares your body for sleep. “Showers can also be very relaxing, so that helps, too,” says Meltzer. If you shower every night around the same time, making it part of a consistent bedtime routine, you’ll see the most sleep value from it, she adds. “Then your body has an expectation of what’s coming next.”
Uncomfortable bedding has been linked to poorer sleep quality, while a comfortable mattress can up the chances of a satisfying snooze—we swear by our Casper mattress. Effect of prescribed sleep surfaces on back pain and sleep quality in patients diagnosed with low back and shoulder pain. Jacobson BH, Boolani A, Dunklee G.

Not convinced? Consider this. One study, published in the journal SLEEP, concluded that people who get 60 minutes of exercise five days per week have more normal REM sleep than non-exercisers. But you might not need to sweat it out for quite that long to reap the benefits. Other findings show that insomniacs who engage in thirty minute spurts of exercise just three or four times a week sleep for nearly an hour longer than sedentary folks, and wake up less frequently during the night.
They’re placed under a category called sedative hypnotics and include benzodiazepines and barbiturates. You’ve probably heard of the benzodiazepines, or psychotropic drugs, called Xanax, Valium, Ativan and Librium, which are also known as common anti-anxiety medications. Because they can induce drowsiness, they can help people sleep, but these drugs can be addictive too — and that’s not a good thing.
Why is working out seemingly so beneficial? The mechanisms aren’t entirely known, but National Sleep Foundation experts say that it could have to do with exercise’s ability promote feelings of relaxation and reduce feelings of stress, anxiety, and depression. Staying active might also help to keep your body’s natural sleep-wake cycle in sync—particularly if you do it outside (more on that below).
Second, we capped melatonin supplements’ per-pill dosage of melatonin at 1.5 mg. While any average melatonin supplement likely contains up to 10 mg of melatonin, Dr. Michael Breus (a clinical psychologist who runs the website thesleepdoctor.com) says that’s far too much for the average person. “The data suggests that the average adult needs between 0.5 and 1.5 mg,” he says.
