"Dark therapy" proposed as a treatment for bipolar disorder

Bipolar disorder often affects the sleeping and waking cycle-and can also be exacerbated by a lack of sleep-recent research into ‘dark therapy’ as a form of treatment for bipolar disorder has provided another possibility, according to an article in the Insight Journal.

Light therapy has been used for years to treat seasonal affective disorder, a form of depression that occurs in winter when there is less available sunlight. Dark therapy works much the same way, but it focuses on exposing the patient to darkness instead of bright light. More specifically, dark therapy blocks out the blue spectrum lights—florescent, incandescent and LED.
