While going through a local newspaper, i came across an article explaining how exposure to too much light at night may cause depression. Ohio state university researchers found that mice kept in a lighted room 24hours a day had more depressive symptoms than that had a normal day night cycle. The inability to escape light seemed to quell the depressive effects. The findings indicate the need to learn more about how artificial light affects humans. Therefore the increasing rate of depressive disorders in humans corresponds with the increasing use of light at night in moderated society. Many are now exposed to unnatural light cycles and that may have real consequence for our health.
