Physiological Demand Anticipation

Meaning

Physiological Demand Anticipation is the fundamental chronobiological function where the body’s internal clocks proactively adjust physiological processes, such as hormone secretion, metabolic enzyme activity, and core body temperature, in advance of predictable daily needs. This anticipatory function, rather than a reactive one, allows the body to optimize performance and maintain homeostasis in the face of environmental changes like waking, eating, or physical activity. A robust anticipatory response is a marker of a healthy, synchronized circadian system.
