During the late '60s and early '70s, sleep studies suggested that the neurotransmitter serotonin may play a role in sleep induction. Later on, research in animals showed that destruction of parts of the brain that housed nerve cells containing serotonin could produce total insomnia. Partial damage to these areas of the brain caused variable decreases in sleep. The percentage of destruction of these particular nerve cells correlated with the amount of slow-wave sleep.
Reading books on electronic devices before bedtime disrupts the body’s natural sleep rhythms, according to research published in the Proceedings of the National Academy of Sciences. In the study, 12 people read a book on an electronic device for 4 hours before bed, in a dimly lit room, for 5 consecutive nights. On another 5 nights, they read a real printed book on the same schedule. When using an electronic device, they were less drowsy, took longer to fall asleep, and were less alert in the morning. According to the researchers, use of electronic devices suppressed melatonin levels, making it more difficult to get a good night’s rest.
There are diagnostic tests that can be helpful for assessing your sleep problems, with special tests for insomnia. It may be helpful to keep a sleep log or use an actigraph (like a fitness tracker) to track your sleep patterns. Further testing with an overnight sleep study called a polysomnogram can also be helpful to identify sleep apnea or restless legs syndrome as potential contributors to insomnia.
Because tryptophan is present in milk and warm milk helps some people feel drowsy, tryptophan became a much sought-after item for the treatment of insomnia at natural food stores. Yet some people who took tryptophan as a natural supplement developed a syndrome eosinophilia-myalgia syndrome (EMS). Some people died. Scientists later believed the deaths were the result of taking the amino acid tryptophan. Not everyone who took tryptophan, however, experienced these side effects. In addition, not everyone who took tryptophan received help for insomnia.
Record how much and when you sleep, fatigue levels throughout the day, and any other symptoms. This serves two purposes: It can identify activities that help or hurt the chances of a good night’s rest, and it’s a useful tool for a doctor or therapist, should you decide to see one. Digital programs like Zeo, YawnLog, and a variety of apps can all make snooze-tracking easier.
Go dark. It’s known that the light from a smartphone interferes with sleep. But what about your bathroom light? If you have the urge to go at night, don’t flick on the lights. “The latest recommendation is to use a flashlight if you need to get up at night,” Gamaldo says, because it offers less visual disruption. And remember: If you do wake up for a bathroom break, it might take up to 30 minutes to drift back off. This is completely normal, she says.
1. Set up a strict routine involving regular and adequate sleeping times (most adults need about seven or eight hours sleep every night). Allocate a time for sleeping, for example, 11pm to 7am, and don’t use this time for anything else. Avoid daytime naps, or make them short and regular. If you have a bad night, avoid sleeping late, as this makes it more difficult to fall asleep the following night. The sad truth is that good sleep does require some discipline.
Gaia is a premium option at $0.30 per serving. However the valerian is sourced from the company’s organic farm in North Carolina, and each bottle comes with an ID number that allows you to track the batch and learn more about the source of your supplement on the manufacturer’s website. If you’re conscious about organic products, the price may be worth it, but know that there are cheaper valerian options out there.
Innovative fibers like Celliant may help you drift off sooner. Used in Amerisleep mattress covers, Celliant is a fabric infused with minerals that absorbs body heat and converts it to infrared waves. It’s been shown to help regulate body temperature (to avoid overheating) and to boost circulation. In one study, people fell asleep 15 minutes faster on a mattress with a Celliant cover.
Unwind by keeping the lights low. Light signals the brain that it's time to wake up. Staying away from bright lights (including computer screens!), as well as meditating or listening to soothing music, can help your body relax. Try to avoid TV, computers and other electronics, and using your phone (including texting) at least 1 hour before you go to bed.
If you’re anxious or distressed at bedtime, the best medicine may be a face full of ice-cold water. When you’re in a full-on state, your nervous system desperately needs to be reset to help you calm down. Submerging your face in a bowl of cold water triggers an involuntary phenomenon called the Mammalian Dive Reflex, which lowers your heart rate and blood pressure. Then it’s off to bed with a soothed system.
Visualization: Involves actively imagining a relaxing scene. You can try it in bed for 20 minutes before falling asleep. Involve all your senses. If you're imagining yourself on a tropical island, think of the way the warm breeze feels against your skin. Imagine the sweet scent of the flowers, look at the water and listen to the waves. The more vivid the visualization and the more senses you involve, the more effective it will be.
Give yourself some dedicated wind-down time. It doesn’t have to be a full hour or an elaborate routine, but try to spend at least 20 to 30 minutes doing something that relaxes you before you try to fall asleep. That could be taking a warm bath or shower, changing into comfy pajamas and sipping a cup of chamomile tea. Or something completely different — so long as it’s relaxing to you.
