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 US scientists.
The study, by a team of neuroscientists at Ohio State University Medical Center partly funded by the US Department of Defense, will give screen-addicted night owls pause for thought.
`The results we found in hamsters are consistent with what we know about depression in humans,` said Ms Tracy Bedrosian, who led the study, published in the journal Molecular Psychiatry.
The researchers - who exposed hamsters to dim light at night and picked up changes in behaviour and the brain that bore striking similarities to symptoms in depressed people - said a surge in exposure to artificial light at night in the last 50 years had coincided with rising rates of depression, particularly among women, who are twice as prone as men.
