General clutter, dirt, even technology can add unwanted stress in the bedroom. Some doctors say it may sound radical, but to really get your rest, those computers, digital clocks, even TV's need to go. They recommend everything with a screen, even your cell phone should be plugged in somewhere else.
Also, don't forget to wash your sheets and pillows at least once a week in hot water. Microscopic bugs called dust mites love to call your mattress home. For some, especially those with allergies, it's a good idea to get a mattress cover.
Doctors also say in order to get a good night of sleep, you need to be in a very dark room. Your body will only release melatonin when it's dark. Melatonin is essentially the hormone in your body that heals you at night and puts you in a dream state helping you get a good night's rest.
