Bright Light Therapy

Meaning

Bright Light Therapy, also known as phototherapy, is a clinical intervention involving timed exposure to a specific intensity and spectrum of light, typically a high-intensity white light, to influence the body’s circadian rhythm and mood. This therapeutic modality is primarily utilized to address seasonal affective disorder, non-seasonal depression, and various sleep phase disorders. Precise timing of light exposure, often in the morning, is paramount for its efficacy in resetting the internal biological clock and normalizing neuroendocrine function.
