5 Things Never to Do Right Before Bed

Researchers have found that before-bed exposure to the blue light from computers, tablets and smart phones suppresses melatonin levels, which can throw off your body clock as well as increase your risk of obesity.

Do: Log off at least one hour before bed, and set your alarm an hour earlier in the morning to catch up on work. You could also try dimming your screen as much as possible, or downloading a program like F.lux, which adjusts your computer's display to be a warmer color at night.
