Chronobiology Operating System

Meaning

The Chronobiology Operating System refers to the complex, hierarchical network of endogenous biological rhythms that dictate nearly all physiological and behavioral processes within the human body on an approximate 24-hour cycle. This master system, centered in the suprachiasmatic nucleus (SCN), orchestrates the precise timing of hormonal secretion, metabolic activity, and the sleep-wake cycle. Maintaining its precise function is paramount for metabolic and endocrine resilience, ensuring that the body’s internal processes align with the external environment. Dysregulation of this system is often termed chronodisruption, a state with significant clinical consequences.
