What Exactly is Sleep Hygiene? Is this Real?

 “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 National Sleep Foundation describes as “practices and habits that are necessary to have good nighttime sleep quality and full daytime alertness.”
Translation: It’s a bunch of things you should and shouldn’t do to make sure you are 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 your work schedule, how much sleep you typically need each night, and whether or not you suffer from a sleep disorder like sleep apnea. Plus, new research continually introduces ideas to help you get better sleep. But here are a few of the basic tenets of sleep hygiene we can all try to follow.
Make your bedroom a restful, sleep-promoting place.
When possible, keep your room dark when you plan to be sleeping — you can use blackout curtains or an eye mask if you need to. Also use white noise to drown out any distracting sounds, and try to set the room at a cool temperature.
