Circadian rhythms direct a wide variety of functions from daily fluctuations in wakefulness to body temperature, metabolism, and the release of hormones. They control your timing of sleep and cause you to be sleepy at night and your tendency to wake in the morning without an alarm. Your body’s biological clock, which is based on a roughly 24-hour day, controls most circadian rhythms. Circadian rhythms synchronize with environmental cues (light, temperature) about the actual time of day, but they continue even in the absence of cues.
People often ask me about whether, and how, to use cannabis for sleep. (I wrote about some dos and don’ts for using cannabis as a sleep tool—you can check it out here.) One of the easiest, most effective ways to harness the relaxing, sleep promoting effects of cannabis? Try using CBD. You’ve probably heard of CBD. It’s showing up everywhere as a therapy to reduce anxiety and improve mental focus. It’s also a natural sleep booster.
Tryptophan. Tryptophan is a basic amino acid used in the formation of the chemical messenger serotonin, a substance in the brain that helps tell your body to sleep. L-tryptophan is a common byproduct of tryptophan, which the body can change into serotonin. Some studies have shown that L-tryptophan can help people fall asleep faster. Results, however, have been inconsistent.
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.
5. If sleep doesn’t come, don’t become anxious or annoyed and try to force yourself to sleep. The more aggravated you become, the less likely you are to fall asleep. Instead, try to clear your mind and relax. For example, I find that making myself feel grateful for something soon sends me off to sleep. Alternatively, get up and do something relaxing and enjoyable for about half an hour before giving it another go. Don't worry too much about losing sleep: lying in bed with your eyes closed can provide some of the restorative benefits of sleep.
Having a few drinks before bedtime will increase your NREM sleep (Stages 1 and 2) and reduce your REM sleep. You’ll remember that REM sleep helps you organize and store your memories. Too little REM sleep can be devastating for the brain and body. In addition, REM sleep is the sleep stage where the most calories are burned. And alcohol is filled with empty calories, so drinking is never a good idea when you’re trying to sleep better or lose weight. See more info on REM sleep here.
Eighteen leading scientists and researchers came together to form the National Sleep Foundation’s expert panel tasked with updating the official recommendations. The panelists included six sleep specialists and representatives from leading organizations including the American Academy of Pediatrics, American Association of Anatomists, American College of Chest Physicians, American Congress of Obstetricians and Gynecologists, American Geriatrics Society, American Neurological Association, American Physiological Society, American Psychiatric Association, American Thoracic Society, Gerontological Society of America, Human Anatomy and Physiology Society, and Society for Research in Human Development. The panelists participated in a rigorous scientific process that included reviewing over 300 current scientific publications and voting on how much sleep is appropriate throughout the lifespan.
Of all the sleep tips you could ever read or hear about, the most important one is to stick to one sleep schedule—every day. This means going to bed and waking up at the same time each day. When sleep has a regular rhythm, your biological clock will be in sync and all of your other bodily functions will go smoother, including your sleep. You are probably squirming as you read this tip, thinking about your own sleep issues and how you have anything but a regular sleep routine.
“I’m a strong advocate of mindfulness and meditation for relaxation,” says Barone, who recommends shutting off electronics 30 to 60 minutes before bed and sitting quietly, focusing on soft music or deep breathing. “And if someone wakes up in the middle of the night, I tell them to do a 10- to 15-minute session of meditation then, too.” If you’re new to meditation, Barone recommends finding a mobile app, audio program, or online video to guide you through some exercises.
Experts say that during the teen years, the body's rhythm (sort of like an internal biological clock) is temporarily reset, telling a person to fall asleep later and wake up later. This change might be due to the fact that the brain hormone is produced later at night for teens than it is for kids and adults. This can make it harder for teens to fall asleep early.
Unless you’re in pain, your sleep aid doesn’t need to include painkillers. Products like Advil PM, which combine antihistamines with painkillers like ibuprofen or acetaminophen, have name recognition. But Dr. Gary Zammit, the executive director of the Sleep Disorders Institute, suggested following this rule when it comes to medications: Treat the problem that you have.
Generally, non-benzodiazepines have fewer drawbacks than benzodiazepines, but that doesn’t make them suitable for everyone. Some may find this type of sleep medication ineffective at helping them sleep, while the long-term effects remain unknown. The U.S. Food and Drug Administration (FDA) recently directed the manufacturers of Ambien and similar sleeping pills to lower the standard dosage due to the serious risk of morning grogginess while driving, especially in women patients. Other side effects include:
If your brain is racing with stressful thoughts, fill it up with up with something a little nicer. "Tell yourself a gentle story — could be a favorite childhood book or movie — and use the same one night after night," says Catherine Darley, ND, of The Institute of Naturopathic Sleep Medicine, Inc. "This is helpful for those people who have an active mind and their thoughts interfere with sleep."
You’ve got an early day tomorrow, and you know you should be asleep — but instead you’re just lying there, wide awake, watching the minutes tick by on the clock. It’s called sleep-onset insomnia, and the irony is, the more you worry about falling asleep, the less likely you’ll be able to. But there are some easy things you can do to break the cycle. Below we discuss simple changes to your lifestyle and your sleep environment that can help you fall asleep faster and get a more restful night’s sleep.
