Physiological Uptime

Meaning

Physiological uptime refers to the body’s state of peak functional capacity and energy availability, extending beyond mere wakefulness. It signifies the duration during which an individual’s biological systems, particularly hormonal and metabolic pathways, are optimized for sustained physical performance, mental alertness, and cognitive clarity throughout the active period of the day. This state is characterized by efficient energy substrate utilization and balanced neurochemical activity.
