Light Therapy

Light therapy, also known as phototherapy, is a treatment that consists of exposure to artificial light. The artificial light is intended to simulate sunlight, and is used in a controlled environment at set times. Light therapy is used to treat a number of circadian rhythm disorders such as jet lag, shift work fatigue, sleep phase and excessive daytime sleepiness. Light therapy is also the main form of treatment for Seasonal Affective Disorder (SAD) which is a common form of depression related to changing seasons.
