Dark Therapy

Meaning

Dark Therapy is a clinical intervention strategy that involves deliberately limiting or eliminating exposure to all light, especially short-wavelength blue light, during the evening and nighttime hours to synchronize and enhance the body’s natural circadian rhythm. The goal is to maximize the nocturnal secretion of melatonin, a key chronobiotic hormone, and promote the transition into restorative sleep. This structured light hygiene is a powerful non-pharmacological tool for managing circadian rhythm disorders, improving sleep architecture, and potentially supporting mental health conditions. It is a precise environmental modulation designed to optimize neuroendocrine function.
