Study: Nightlights Linked to Depression
A new study suggests nightlights and other light emitted from computer screens and televisions at night may contribute to depression.
The study from Ohio State exposed hamsters to dim, artificial light for 8 hours at night, and compared their behavior to hamsters who spent nights in total darkness. After a month, those with nightlights were less active during the day and showed more signs of depression -- including less interest in drinking sugary water.
The dim lights were the equivalent of sleeping with a television on.
