Description
Sleepiness is commonly described by the two-process model, in which sleep pressure—a homeostatic drive that accumulates during wakefulness—and the circadian rhythm—an endogenous ~24-hour physiological cycle—interact to regulate alertness. Although this framework explains the primary fluctuations in alertness, substantial inter-individual variability remains unexplained. In this presentation, we apply mathematical modeling to long-term sleepiness data to investigate temporal dynamics beyond the canonical circadian scale and examine potential sex-related differences in these patterns.
