Dark therapy

Dark therapy is the practice of keeping people in complete darkness for periods of time in an attempt to treat psychological conditions. The human body produces melatonin hormone which is responsible for supporting the circadian rhythms. Dark therapy is claimed to block blue wavelength lights to stop the disintegration of melatonin. Some claim that this process improves the health of human body, such as by minimizing headaches, chronic fatigue syndrome, and insomnia.

Some claim that this process improves the health of human body, such as by minimizing headaches, chronic fatigue syndrome, and insomnia. The idea originated in 1998 from research which suggested that systematic exposure to darkness might alter people's mood. More recently, with the discovery of intrinsically photosensitive retinal ganglion cells, it has been hypothesized that similar results could be achieved by blocking blue light, as a potential treatment for bipolar disorder. Researchers exploring blue-blocking glasses have so far considered dark therapy only as an add-on treatment to be used together with psychotherapy, rather than a replacement for other therapies.
