Abstract

A primary role for melatonin relates to the human circadian system. Endogenous melatonin production is the ideal marker for biological time. Its physiological function in humans probably relates to the fact that low physiological doses of melatonin cause phase advances when administered in the morning and cause phase delays when administered in the afternoon/evening, the treatment of choice for free-running totally blind people. Bright light, the treatment of choice for circadian abnormalities in sighted people, causes phase advances when scheduled in the morning and phase delays when scheduled in the evening. Future interest in this area is expected to markedly increase.
