Circadian Biology

Meaning

Circadian biology is the scientific study of the innate, approximately 24-hour cycles in the physiological processes of living beings, known as circadian rhythms. These internal biological clocks regulate critical functions, including the sleep-wake cycle, hormone secretion patterns, metabolism, and core body temperature. Maintaining synchronization between the internal clock and the external light-dark cycle is paramount for hormonal health and overall well-being. Disruption of these rhythms, often seen in shift workers, can lead to metabolic and endocrine dysfunction.
