Biological Clock

Meaning

The biological clock refers to the intrinsic, self-sustaining timekeeping system found in nearly all living organisms that regulates biological processes on a roughly 24-hour cycle. This internal rhythm is formally known as the circadian rhythm, a critical component of human physiology. It dictates the timing of essential functions, including sleep-wake cycles, hormone secretion, and metabolic rate. Maintaining a robust and synchronized biological clock is paramount for optimal health and endocrine function.
