Circadian Rhythm Synchronicity

Meaning

Circadian Rhythm Synchronicity describes the state where the body’s internal 24-hour biological clock is precisely aligned with the external environmental cues, primarily the light-dark cycle. This alignment is critical for the coordinated, cyclical release of hormones like cortisol and melatonin, which dictates sleep-wake cycles and metabolic processes. Achieving this synchronicity supports optimal endocrine function, energy regulation, and overall metabolic health. Deviation from this state is known as chronodisruption.
