Late Night TV/Computer Sessions Linked to Depression


Researchers at Ohio State University found that chronic nighttime exposure to artificial light, like that from computers and television, can lead to depression.

The researchers were able to trace the protein involved in depression that is produced by artificial light exposure. When they blocked the protein in test animals, the animal's depression lifted.

ANI reports that the research adds evidence to previous theories linking light from television and computers at night to depression and even obesity.

"These findings add to the growing evidence that suggest chronic exposure to artificial light at night may play some role in the rising rates of depression in humans during the past 50 years," said study author Tracy Bedrosian, a neuroscientist at Ohio State.

The study was published in the journal Molecular Psychiatry.
