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 blocks blue wavelength lights to stop the disintegration of melatonin and helps improve the health of human body. It can also relatively minimize headaches, chronic fatigue syndrome, insomnia, and more.[
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.
