We evolved from bacteria in the ocean that could differentiate sunlight from darkness—that’s what ended up forming the human eye. That means every organism is responsive to a circadian rhythm that’s largely dictated by sunlight. The photo receptors in our eyes pick up on sunlight, which controls the release of melatonin and all these other neurotransmitters that dictate your energy levels throughout the day.
You should then spend 10 seconds trying to clear your mind before thinking about one of the three following images: You're lying in a canoe on a calm lake with nothing but a clear blue sky above you; you're lying in a black velvet hammock in a pitch-black room; or you say "don't think, don't think, don't think" to yourself over and over for about 10 seconds.
Research has shown that changing your lifestyle and sleep habits is the best way to combat insomnia. Even if you decide to use sleeping pills or medications in the short term, experts recommend making changes to your lifestyle and bedtime behavior as a long-term remedy to sleep problems. Behavioral and environmental changes can have more of a positive impact on sleep than medication, without the risk of side effects or dependence.
The influence of tryptophan on sleep continues to be studied in major sleep laboratories across the nation. While this amino acid is not available as a natural dietary supplement or sleep remedy, you can easily include tryptophan in your diet through food sources such as turkey, cheese, nuts, beans, eggs, and milk. You can also boost serotonin levels in the brain -- helping you to feel calm and sleepy -- by eating foods rich in carbohydrates.
We swear, we’re not pulling your leg. Try and remember what you physically feel like when you’re tired: Do your arms go limp? Do your eyes roll back into your head? Now, mimic those physical signs: While lying in bed, think of a weight pressing evenly across your entire body. Okay, that sounds a little scary, but concentrating on the weight will stop other thoughts (e.g. the school lunches you still have to pack for tomorrow) from distracting you. Next thing you know, you’ll find yourself waking up the next day, wondering how the heck you fell asleep so fast.
We tend to think of sleep as a time when the mind and body shut down. But this is not the case; sleep is an active period in which a lot of important processing, restoration, and strengthening occurs. Exactly how this happens and why our bodies are programmed for such a long period of slumber is still somewhat of a mystery. But scientists do understand some of sleep's critical functions, and the reasons we need it for optimal health and wellbeing.
Block out unwanted noises. Noise can impact your ability to get to sleep as well as your overall sleep quality. Try listening to a radio program or podcast that's not too engaging to help block out noise distractions such as traffic, as well as worrisome thoughts. Listen to something that is soft-spoken instead of loud, and something you enjoy but not so much that you will stay up just to listen to it. Recommended podcasts include: 
Clean your room. Get rid of the cobwebs, dust the shelves, vacuum the floor. Empty the wastepaper basket. Remove dirty plates, cups, and water-bottles. A clean room sets the emotional stage for your room being a safe, healthy place, not a neglected dumping-ground to wallow in. Also, regular cleaning can alleviate allergies which can disrupt sleep. It also keeps pests like mice, rats, and cockroaches from invading your space.
The National Sleep Foundation reports that insomnia is common among those who are depressed and notes that people with insomnia have a much higher risk of becoming depressed. (11) Research from the Department of Psychology at the University of North Texas shows that depression may affect many aspects of sleep, from getting to sleep to staying asleep. By treating depression using St. John’s wort, you may be able to find that restful sleep your body and mind longs for. (12)
4. Sleep in a familiar, dark, and quiet room that is adequately ventilated and neither too hot nor too cold. If possible, try to use this room for sleeping only, so that you come to associate it with sleep. In time, your room could become another sleeping cue. If your sleeping environment is sub-optimal, try to use aids such as earplugs or a sleeping mask.
The most important thing is taking that time off—it’s more conducive to your productivity. A lot of times people think they can like fight through and push harder and harder and harder to get better results, but sleep can give you that, too. When you transition in and out of sleep, your brain produces theta waves, which help you think more divergently. That’s why a lot of times when you wake up from a power nap or from sleeping, you’ll be able to solve that intractable problem that you couldn’t earlier in the day. That’s one of the reasons I think taking a break—whether it’s meditation or nap—during that circadian dip can be much more conducive to productivity.
When you first start, you’ll be desperate to just take in another breath, or you’ll want to speed up your counting, but if you stick to the numbers (or at least try to), and don’t take any breaks (in other words, consecutively repeat the 4-7-8 without resuming regular breathing), you can literally feel your heart rate slow down, your mind get quieter, and your whole body physically relax. It washes over you like a calming, relaxing drug. I can never remember getting past the first set of 4-7-8.

How CBD helps sleep: Research shows CBD can significantly reduce insomnia symptoms. It also can increase overall sleep amounts, according to studies. In particular, CBD has been shown to reduce insomnia in people who suffer from chronic pain. In smaller doses, CBD stimulates alertness and reduces daytime sleepiness, which is important for daytime performance and for the strength and consistency of the sleep-wake cycle. One thing I really like about CBD? New research shows it relieves anxiety without causing changes to healthy sleep-wake cycles.
“Pregnant women see an increase in sleep problems in the first and last trimester. During the first trimester, sleep problems are caused by hormonal changes, and during the last trimester, the baby is larger and creates pressure on the diaphragm, which creates breathing problems,” Chokroverty says. “The baby also puts pressure on the bladder, so a pregnant woman needs to wake up during the night to urinate. Lower back pain and stress and anxiety during the last trimester also cause sleep disturbances.”
It depends on the sleep aid. Consumer Reports writes that while the antihistamine diphenhydramine isn’t physically addictive, it can be psychologically addictive. On the other hand, Mayo Clinic says that you’re unlikely to become dependent on melatonin with short-term use. Again, it’s best to talk to your doctor to figure out which option is best for you.
The other benefit of speaking with a healthcare professional is that you can discuss the use of sleeping pills. There are two major classes of prescription medications that can help you sleep: benzodiazepines and nonbenzodiazepines. The list of sleeping pills is long and includes drugs like Ambien, Lunesta, Sonata, Trazodone, Belsomra, and others. These should not be used longer than a few weeks and if insomnia persists, you may want to seek other treatment. In particular, you can ask for a referral to a psychologist who might be able to teach you cognitive behavioral therapy for insomnia (CBTI) techniques.
It'll be easier to fall asleep if your room is completely dark, so cover up any blinking clocks, turn off your lamp, and pull your curtains to block lights from the street. And remember for tomorrow night: always dim your lights a few hours before bed. As Logie tells me, exposure to bright lights — like from your TV, lamps, or phone — in the evening can make it more difficult to fall asleep.
Slowed responses and dulled concentration from lack of sleep don't just affect school or sports performance, though. More than half of teens surveyed reported that they have driven a car while drowsy over the past year and 15% said they drove drowsy at least once a week. The National Highway Safety Traffic Administration estimates that more than 100,000 accidents, 40,000 injuries, and 1,500 people are killed in the U.S. every year in crashes caused by drivers who are simply tired. Young people under the age of 25 are far more likely to be involved in drowsy driving crashes.
Fortunately, doing that is easier than you might think. Below, we’ll take a look at the multitude of lifestyle changes—both big and small—that you can make to help you sleep better. We’ll also explore proven herbal remedies that can give you a relaxation boost when you really need it, minus the side effects that tend to come with prescription meds.
Sleeping with Fido isn’t so bad, according to a new Mayo Clinic study that found people who had a dog in the bedroom slept better than those who didn’t. But don’t let your pooch crawl under the covers: Participants who snuggled with their pets had poorer sleep quality than those who didn’t. If pet "co-sleeping" sounds like the insomnia cure for you, be sure your furry friend sleeps on the floor or in a pet bed of their own nearby so you both get an undisturbed, restful sleep. (Here are 5 ways to lose weight with your pet—so you can both live longer.)
You know a good night’s sleep is the key to a happy and well-rested tomorrow. And getting enough shut-eye can help you drive more safely, maintain a healthy weight, and even lower your risk for heart disease and diabetes. But if you’re stuck in a cycle of tossing and turning—and then start stressing about the fact that you’re tossing and turning—it's all too easy to feel frustrated. Not so fast: With these tips you’ll be snoozing within minutes of your head hitting the pillow.
