Light therapy

Light therapy is the use of a high-intensity fluorescent lamp (usually 10,000 lux) to treat a certain type of depression that occurs during the fall and winter months (seasonal affective disorder).

Lamps used for light therapy are brighter than ordinary indoor lighting. A person sits in front of the light for about 30 minutes a day. A person can usually read, use a computer, or do other types of desk work while sitting in front of the light.
