Whittle Your Waist and Sleep Better in the Bedroom You've probably sussed out that too much light makes it harder to sleep soundly. Did you know that light exposure at night increases your risk of obesity, too? Researchers came to this conclusion when researching links between nighttime light and breast cancer. Basically, light exposure in the wee hours kicks off an awful chain reaction in the body. First it interferes with your sleep patterns, aka circadian rhythms, which affects metabolism. The tweak in your metabolism increases your likelihood of obesity, which increases your likelihood of certain diseases -- breast cancer, depression, mood disorders and reproductive problems, among others.
How to deal? Position your bed on the side of the room farthest from the window and invest in thick curtains to block light sources. While you're at it, do away with as many light-emitting electronic devices as possible in the bedroom. Blue light -- the kind emitted from your computer, TV and digital alarm clock -- is known to disrupt sleep patterns.
