Chronotherapeutic Light Dosing

Meaning

Chronotherapeutic light dosing is a clinical strategy that involves the precise administration of light of specific intensity, spectrum, and duration at carefully timed points in the 24-hour cycle to intentionally shift or regulate the body’s internal circadian clock. This intervention is primarily utilized to treat circadian rhythm sleep disorders, such as delayed sleep phase syndrome, and to improve mood and alertness. The efficacy of the treatment relies entirely on the dose of light exposure coinciding with the most sensitive phases of the body’s master pacemaker.
