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.[14]
Melatonin supplements are widely recommended for various sleep conditions, but the best evidence is for help with sleep problems caused by shift work or jet lag. Melatonin is a naturally-occurring hormone that regulates the sleep-wake cycle in the brain. It is produced from serotonin when exposure to light decreases at night. It is used in conditions where sleep is disordered due to low levels of melatonin at night such as aging, affective disorders (e.g. depression), delayed sleep-phase disorder, or jet lag. 

Getting outside in the sun for 15 minutes each morning helps to regulate the production of melatonin, the sleep hormone. Your internal body clock (the circadian rhythm) runs on a 24-hour schedule and functions best when you are exposed to a regular pattern of light and dark. Malfunctions in your circadian rhythms because of changes in light and dark exposure can negatively impact your ability to get a good night’s sleep.

Social or recreational drugs like caffeine, nicotine, and alcohol may have a larger impact on your sleep than you realize. Caffeine, which can stay in your system as long as 14 hours, increases the number of times you awaken at night and decreases the total amount of sleep time. This may subsequently affect daytime anxiety and performance. The effects of nicotine are similar to those of caffeine, with a difference being that at low doses, nicotine tends to act as a sedative, while at high doses it causes arousals during sleep.
She happens to be a licensed wellness practitioner who studies meditation, stress, and breathing techniques, and she told me it would change my life. You simply breathe in through your nose for four seconds, hold your breath for seven seconds, and exhale through your mouth for eight seconds. She explained that the studied combination of numbers has a chemical-like effect on our brains and would slow my heart rate and soothe me right to sleep that night. “It works,” she told me. “It’s crazy.”
You have a peak moment of awakeness during the morning. After lunch you usually have a glucose spike, especially if you have a big heavy lunch, like a cheeseburger. That glucose spike combined with a circadian dip gives you a period of fatigue between around 2 and 4pm. You’ll then have another spike in alertness right before dinner, and then you’ll start getting tired again closer to bedtime. That’s your 24-hour circadian rhythm, basically.
Valerian is one of the most common sleep remedies for insomnia. Numerous studies have found that valerian improves deep sleep, speed of falling asleep, and overall quality of sleep. However, it's most effective when used over a longer period of time. One caveat? About 10% of the people who use it actually feel energized, which may keep them awake. If that happens to you, take valerian during the day. Otherwise, take 200 to 800 milligrams before bed.
What I Did: Every night, I wrote down the time I ate dinner, when I turned off electronics, and what time I turned out the light. The next morning I added my wake up time and a brief note about how I slept. Even after only a week or two sleep journaling, I saw some interesting patterns (or lack of patterns) and knew what I needed to work on to get better sleep.
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.
Certain protein-rich foods like milk, eggs, peanuts, and soy contain an amino acid called tryptophan that causes sleepiness, says Alissa Rumsey, MS, RD, founder of Alissa Rumsey Nutrition and Wellness. For best results, combine these foods with a source of carbohydrates, which help more tryptophan enter the brain. Some recommendations: roasted soybeans, peanuts, sunflower seeds, cheddar cheese, canned tuna, and pistachios. You don't need much: "Even smaller snacks can provide a tryptophan dose that studies have shown to be significant in helping with sleep," Rumsey says.
Falling asleep isn't always as simple as placing your head on a pillow and shutting your eyes. Thoughts and worries might race their way through your mind, or getting comfortable might seem impossible. Fortunately, from relaxation techniques to changing your sleep routine, there are lots of ways to fall asleep quickly and improve your sleep quality.
If you’re American, chances are you aren’t getting enough sleep. A Gallup poll (2005) of Americans past age 50 found only 32% reported getting a good night’s sleep routinely. 56% said they got between 6 and 8 hours a night. The US Dept of Health and Human Services reports that “The odds of being a short sleeper (defined as someone who sleeps less than 6 hours a night) in the United States have increased significantly over the past 30 years.”

If your mind tends to race as soon as your head hits the pillow, put the brakes on this sleep-stealing habit by distracting yourself from rehashing the day’s events. One tip Breus offers his patients: Count down from 300 in multiples of three. “Because this task is mathematically complicated to do in your head,” he explains, “it forces your brain to focus on something else besides your worries.”
Cognitive behavioral therapy (CBT) usually focuses on discovering and changing the thoughts or feelings that trigger depression and stress but it can be a natural insomnia cure, too. Research has found that CBT can retrain your body and mind for faster, deeper sleep. In a Harvard University study of 63 insomniacs, CBT was more effective than prescription sleeping pills; it cut the time it took for participants to fall asleep in half and improved sleep quality by 17 percent. You can practice CBT at home, too. The National Sleep Foundation recommends keeping a sleep diary of when you go to bed and wake up, as well as banishing daytime naps. Instead, adopt a regular sleep schedule; that means going to bed and waking up at the same time every day.
But with schools continuing to open at ridiculously early times and bosses still mostly unwilling to embrace the science calling for shorter workdays, it's hard to see how most of us are realistically going to either sleep in later or get to bed earlier (especially if, you know, you want to squeeze in fluffy extras like seeing your loved ones, feeding yourself, and enjoying life in the evenings).

The key here is to keep dinners simple and moderate in portion, so you won’t be bothered with indigestion later. Eating carbs four hours before sleep was more effective than one hour prior in the study, meaning planning your evening meals could prove helpful. Spicy foods can also affect your ability to fall asleep quickly, so keep that in mind, too.
