Chronotype asymmetry arises from stochastic sleep homeostasis under circadian entrainment

2026-02-20

Abstract excerpt

Study Objectives: Chronotype, typically defined by the mid-sleep phase on free days, is often interpreted as a direct proxy for circadian phase. However, a fundamental paradox challenges this assumption: worldwide chronotype distributions show a heavy right skew, whereas circadian period distributions show a slight left skew. We investigated whether fast, noisy cortical processes in homeostatic sleep pressure dyna...
