Biological Clock Regulation

Meaning

Biological clock regulation refers to the intricate, genetically encoded process of managing the body’s circadian rhythms, which are 24-hour cycles governing nearly all physiological and behavioral functions. This regulation is centrally controlled by the suprachiasmatic nucleus (SCN) in the hypothalamus, which synchronizes peripheral clocks in tissues throughout the body. Optimal regulation ensures that hormonal release, metabolic processes, and sleep-wake cycles occur at the appropriate time, maintaining systemic homeostasis. Disruption of this system, often through lifestyle factors, is clinically linked to endocrine dysfunction and accelerated aging.
