Biological Timekeeping

Meaning

Biological Timekeeping refers to the intrinsic, genetically encoded system that regulates the timing of physiological processes, operating on circadian, ultradian, and infradian rhythms. This internal clock, primarily governed by the suprachiasmatic nucleus in the hypothalamus, dictates critical functions such as hormone secretion, sleep-wake cycles, and metabolic rate. Disruptions to this precise timekeeping mechanism can significantly impair hormonal health and accelerate age-related decline.
