LUBBOCK, TX (KCBD) - Too much light at night could lead to depression. According to a new study from Ohio State, this could be important for intensive care units in hospitals where the lights are often kept on all night. 

Researchers subjected lab mice to light 24-hours a day for three weeks straight and then compared them with mice in a typical light-dark cycle.  The mice that lived in constant light showed more signs of depression.  Researchers say this might also apply to those who work the night shift or stay up late into the night watching TV.
