CircadianRhythm

Meaning

An endogenous, self-sustaining oscillation of biological processes in living organisms that cycles approximately every 24 hours, regulating critical physiological and behavioral functions. This fundamental rhythm dictates the temporal organization of the endocrine system, controlling the pulsatile release of hormones, core body temperature, and the sleep-wake cycle. Maintaining a robust circadian rhythm is essential for systemic homeostasis and long-term health resilience.
