Description
Circadian rhythm regulation involves a complex interplay between the central clock in the suprachiasmatic nuclei and peripheral oscillators throughout the body. Melatonin serves as the primary hormonal signal conveying darkness information to these systems.

Exogenous melatonin administration influences circadian phase positioning, with the direction and magnitude of phase shifts depending on the timing of administration. Evening doses advance the circadian clock, while morning doses may cause phase delays.

Clinical applications of melatonin extend beyond sleep induction to include circadian rhythm resynchronization in jet lag, shift work disorder, and delayed sleep-wake phase disorder. Dose-response relationships vary across these conditions.
