Chronotype Consistency

Meaning

Chronotype consistency is the sustained practice of adhering to a regular sleep-wake schedule that closely matches an individual’s innate, genetically determined preference for the timing of sleep, even on non-work days. Maintaining this consistency is paramount because it minimizes “social jetlag,” the metabolic and psychological stress caused by a mismatch between the internal biological clock and the external social schedule. It is a fundamental component of optimal sleep hygiene, directly supporting stable hormonal balance and cognitive function.
