The Darker the Better for a Good Night’s Sleep
Although it may seem like common sense to sleep in a dark room to get a better night’s sleep, many people don’t. Look around your bedroom—how many sources of light do you have? You might be surprised to find that lots of things are leaking a little light into the darkness you think you’re surrounding yourself with when you flick the light switch off at bedtime.
Light colored curtains can let in glare from outside streetlights. Electronic equipment in “sleep mode” can give off a lot of light. Discarded laptops can cast blue and green glows. Clock radios send light into the darkness of your room too. Operating lights on power bars also add red light. Pretty soon, your room is not nearly as dark as you think it is.
