Logging late night hours in front of artificial light sources like the computer or TV, could be hurting your mental health.

FOX's Colleen Cappon has more in today's edition of Housecall For Health:

If you spend late nights by the TV or computer, one study says you may be increasing your risk of depression. Neuro-scientists at Ohio State University Medical Center exposed hamsters to dim light at night and studied their changes in behavior. They found striking similarities to symptoms in depressed people and believe the surge in exposure to artificial light has played a big role in the increasing rates of depression in the last 50 years.
