Melatonin. Melatonin is a naturally occurring hormone that increases at night. It is triggered by darkness and its levels remain elevated throughout the night until suppressed by the light of morning. Although melatonin does not appear to be particularly effective for treating most sleep disorders, it can help sleep problems caused by jet lag and shift work. Simple exposure to light at the right time, however, might be just as effective. If you take melatonin, be aware that it can interfere with certain blood pressure and diabetes medications. It’s best to stick with low doses—1 to 3 milligrams for most people—to minimize side effects and next-day drowsiness.
7. Caffeine is also a stimulant and is present in coffee (100-200 mg), soda (50-75 mg), tea (50-75 mg), and various over-the-counter medications. Caffeine should be discontinued at least four to six hours before bedtime. If you consume large amounts of caffeine and you cut your self off too quickly, beware; you may get headaches that could keep you awake.
Herbal teas like chamomile and valerian act as a mild sedative. They relax the body and make you feel like your eyes are too heavy to keep open. Of all the herbal teas, I recommend the Celestial Extra Sleepy Time Tea. Not to throw a product placement out there, but this stuff works. It contains pretty much everything that contributes to sleep - chamomile, tilia estrella, and valerian. The combination in this is like a slumber guarantee.
Anyway, basically your biggest zeitgeber is sunlight, and that’s the environmental cue that controls energy levels as well. But then also timing of meals, exercise, and having a consistent bedtime are all zeitgebers that impact your circadian rhythm. A bigger part of the problem is that we’re indoors so much now, so we don’t get that natural occurring sunlight when you wake up in the morning. That’s one of the best things that you can do to entrench your circadian rhythm.
Sleep needs and patterns of sleep and wakefulness are not the same for everyone. The first step in determining your need for sleep is through self-evaluation. Ask yourself: "How tired do I feel during the daytime? When do I feel most alert? When does fatigue set in?" Even moments of sleepiness that you may think of as routine, for instance, falling asleep on the subway on the way to work, or during a lecture, are likely a sign that you are not getting enough sleep.
You’ve likely been told over and over again that a good night’s rest equals eight hours of sleep. But research shows it’s not the number of hours you sleep that matters the most – it’s the quality of the hours you are getting. The largest sleep study ever conducted on 1.1 million people shows that it’s quality, not quantity, that matters most. The researchers found that participants who slept only six and a half hours a night lived longer than those who slept eight hours. It’s easy to conclude that you’ll live longer if you sleep for six and a half hours a night, but the reality is more complicated. It’s possible that the healthiest people simply need less sleep. And when you’re getting good-quality sleep, you likely need less of it.
Other potential health benefits: Melatonin may help to guard against cognitive impairment and neurodegenerative disease. It’s also being investigated as a therapy for some cancers. Supplemental melatonin may be effective at improving sleep quality and sleep quantity in people with ASD, and also may help improve daytime behavior. Melatonin has shown promise as a natural treatment for a range of conditions, including fibromyalgia, menopause, and irritable bowel syndrome.
Try “belly breathing.” Controlled, deep breathing is simply a way to direct your mind away from thoughts that might keep you awake. If you find your mind racing as you lie down to go to sleep, place a hand on your belly and breathe in deeply through your nose — so deeply that can feel the air filling your abdomen. Hold it for a couple of seconds, and then breathe out through your mouth. Breathe mindfully like this for a few minutes, just trying to focus your attention on the rising and falling of your belly as you inhale and exhale. If your mind starts to wander, just bring it back to your breathing. The more often you practice this relaxation technique, the easier and more effective it will be.
