Melatonin Timing

Meaning

Melatonin Timing refers to the precise scheduling of melatonin secretion or exogenous administration relative to an individual’s internal circadian rhythm and external light exposure. This timing is a critical determinant of the hormone’s efficacy in regulating the sleep-wake cycle, as melatonin acts as a powerful chronobiotic agent that signals darkness to the body. Clinically, understanding an individual’s Dim Light Melatonin Onset (DLMO) is essential for effectively treating circadian rhythm disorders and optimizing sleep hygiene.
