Sleep Chronotype

Meaning

Sleep chronotype refers to an individual’s innate preference for sleep and wake times, largely governed by their endogenous circadian rhythm. It reflects the timing of an individual’s peak alertness and sleep propensity within a 24-hour cycle, categorizing people into distinct types like “larks” (early risers) or “owls” (late sleepers). This biological predisposition is influenced by genetic factors and environmental light exposure.
