“Sleep hygiene” is one of those buzzy phrases everyone is talking about. But what does it actually mean?

Sleep hygiene is a set of behaviors that the American Academy of Sleep Medicine describes as “a series of healthy sleep habits that can improve your ability to fall asleep and stay asleep. These habits are a cornerstone of cognitive-behavioral therapy, the most effective long-term treatment for people with chronic insomnia. ”

Translation: It’s a bunch of things one should and shouldn’t do to make sure an individual getting adequate sleep, and enough energy during the day.

Sounds sensible, right? The recommended practices can vary from person to person, depending on things like work schedule, how much sleep a person typically needs each night, and whether or not the individual suffers from a sleep disorder like sleep apnea. Plus, new research continually introduces ideas to promote better sleep. But here are a few of the basic tenets of sleep hygiene we can all try to follow.

Make the bedroom a restful, sleep-promoting place.

When possible, keep the room dark when planning to sleep — people can use blackout curtains or an eye mask if needed. Also use white noise to drown out any distracting sounds, and try to set the room at a cool temperature.

Speaking of temperatures? For those prone to sleeping hot, it might be a good idea to invest in a cooling mattress.

Try sticking to a regular bedtime.

Those able to stick to a nighttime routine will find their bodies naturally learn when it’s time for bed. People should find a bedtime routine that works them and then go to bed — and wake up — at the same time every day.

Avoid consuming too much caffeine.

Everyone processes caffeine differently, but experts recommend avoiding caffeine during the late afternoon and evening (assuming one works a 9-5 rather than the night shift, that is). Consuming caffeine too late in the day can make it difficult for a person to fall asleep at night. Try cutting off the coffee intake after 2 pm.


Don’t watch TV, read, or work in bed.

Doing this trains the brain to associate being in bed with being awake and focused. In reality, one wants to only use the bed for sleep and sex.

Keep the naps short.

According to the Mayo Clinic, people should aim to nap for 10-20 minutes. “The longer you nap, the more likely you are to feel groggy afterward.” However, they explain that young adults might be able to tolerate longer naps.
