Valerian. Like chamomile tea, folk practitioners have turned to the root of this flowering plant to easy anxiety and promote relaxation. And it works: According to a review of sixteen studies, valerian root is shown to help people doze off faster and sleep more soundly. It might not be ideal for long-term use, though, so talk with your doctor before starting a valerian regimen.
Want help achieving and maintaining a healthy weight? Aim for eight hours of sleep a night. Research suggests that appetite-regulating hormones are affected by sleep and that sleep deprivation could lead to weight gain. In two studies, people who slept five hours or less per night had higher levels of ghrelin – a hormone that stimulates hunger – and lower levels of the appetite-suppressing hormone leptin than those who slept eight hours per night. So make sure getting adequate sleep is near the top of your optimum health checklist!
I haven’t seen a study that empirically shows that it’s helpful. There is certainly a false myth that we need eight hours of continuous sleep: I think it’s possible to have your sleep be a little bit broken up and be perfectly healthy—but getting that eight hours is crucially important. The thing is that the placebo effect in some of these polyphasic sleep methods runs really high.
Melatonin is the hormone that controls sleep, so it's no wonder that it naturally induces sleep. Although some experts recommend taking higher doses, studies show that lower doses are more effective. Plus, there's concern that too-high doses could cause toxicity as well as raise the risk of depression or infertility. Take 0.3 to 0.5 milligrams before bed.
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.
What you’re eating and drinking and when you’re enjoying it affects your sleep. Try to finish eating 2 to 3 hours before bedtime so your whole system is ready to relax. Drink alcohol in the early evening instead of right before bed so your body has time to digest it before you hit the sack. Make caffeine a morning-only drink and stick to other beverages in the afternoon and evening. Caffeine stays in your system longer than you might think and can disrupt your sleep.
A sleep deficit affects everything from someone's ability to pay attention in class to his or her mood. According to a National Sleep Foundation Sleep in America poll, more than 25% of high school students fall asleep in class, and experts have tied lost sleep to poorer grades. Lack of sleep also damages teens' ability to do their best in athletics.
From having occasional difficulty sleeping to insomnia, there is a lot you can do to get a better night's sleep, feel refreshed when you awake, and remain alert throughout the day. It's called "sleep hygiene" and refers to those practices, habits, and environmental factors that are critically important for sound sleep. And most of it is under your control.
The research team, led by Floor Kroese, surveyed 177 people on Amazon's Mechanical Turk to assess what bedtime procrastination is and who is likely to do it. They asked participants to rate, on a scale of 1 (almost never) to 5 (almost always) how much the following statements applied to them ("R" items are those that are not typical of bedtime procrastinators):
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.
Sleeping pills and other sleep-promoting pharmaceuticals can offer a short-term solution to a temporary bout of insomnia. And plenty of people use them. But often, prescription sleep aids come with unpleasant side effects like headaches, sore muscles, constipation, dry mouth, daytime fatigue, trouble concentrating, dizziness, and more. Add them all up, and they’re about as bad—if not worse–than your garden variety sleep deprivation.
Keep your room cool, clean, dark, and quiet. Do your best to keep the temperature in your bedroom just below 70 °F (21 °C). Sleeping in a hot and uncomfortable area is not a good or relaxing way to sleep, so do your best to get air regulation throughout the room. Clean up regularly, and change your sheets every 1 to 2 weeks, or whenever they’re dirty. A cluttered space can increase stress, and it can be tough to relax if your sheets are smelly.
Alcohol may initially sedate you, making it easier to fall asleep; however, as it is metabolized and cleared from your system during sleep, it causes arousals that can last as long as two to three hours after it has been eliminated. These arousals disturb sleep, often causing intense dreaming, sweating, and headache. Smoking while drinking caffeine and alcohol can interact to affect your sleep dramatically. These sleep disturbances may be most apparent upon awakening, feeling unrefreshed, groggy, or hungover.
Wear socks to bed. While a cooler core body temperature helps you fall asleep faster and get more restful sleep, cold extremities (hands and feet) can have the opposite effect. If you tend to have cold feet at bedtime, put on a pair of cozy socks, rest your feet on a heating pad, or pile an extra blanket on the foot of your bed. If none of those appeal to you, try wearing a pair of warm slippers in the evening so that your feet will be toasty when you climb in bed for the night.
