Light therapy

Light therapy

Light therapy is the shining of bright light into your eyes – typically for a half hour each session. Since the 1980’s, light therapy has become the first line treatment for winter blues and SAD. Bright light can also be used to shift your circadian (wake/sleep) cycle, so it is used to prevent jet lag, minimize work shift change fatigue, and help abnormal sleep phase insomnias.

 

Shining bright light into your eyes:

a) suppresses brain melatonin, causing wakefulness,

b) enhances brain serotonin, causing mood elevation.

Light therapy takes advantage of these effects to alter your circadian rhythm to prevent jet lag and work shift change fatigue and some insomnias, as well as to treat winter blues
