Daylight Entrainment

Meaning

Daylight Entrainment is the deliberate process of utilizing natural, bright daylight exposure, particularly in the early morning, to precisely synchronize the body’s intrinsic circadian rhythm with the external 24-hour solar cycle. This specific environmental input acts as the most potent zeitgeber for the human biological clock, directly influencing the timing of sleep-wake cycles, core body temperature fluctuations, and the critical diurnal release of hormones like cortisol and melatonin. Effective daylight entrainment is a cornerstone of optimizing hormonal health, metabolic function, and overall sleep architecture. It is a non-pharmacological strategy for stabilizing physiological rhythms.
