Turning off the TV and computer at night could help you get a better night's sleep.

New research suggests not unplugging at night could affect your mental health.

Ohio State researchers found that female hamsters with chronic exposure to dim light at night showed signs of depression, including: reduced activity, less interest in treats and changes in the brain similar to those of depressed people. The symptoms went away once they returned to a schedule with eight full hours of total darkness each day. The study was published online in Nature's Molecular Psychiatry.
