Researchers: Mood caused by light

Headline Goes Here

HOUSTON - Sitting in front of a computer or TV screen late into the night or leaving it on when you fall asleep could increase your chances of becoming depressed, according to a study by U.S. scientists.
The study, by a team of neuroscientists at Ohio State University Medical Center, partly funded by the U.S. Department of Defense, will give screen-addicted night owls pause for thought.
The findings suggest exposure to artificial light at night may have contributed to the rising rates of depression over the last 50 years, said study researcher Tracy Bedrosian.
