Sleep Hygiene and Early Bedtime: Physiologic Mechanisms, Cognitive Effects, and Health Outcomes
Sleep hygiene and early bedtime are behavioral interventions aimed at stabilizing circadian timing, optimizing sleep architecture, and improving daytime function. The core premise is that consistent, sufficiently early sleep allows the brain and body to align biological rhythms—particularly the sleep-wake cycle—with environmental light-dark cues. While the phrase “Sleep early” may appear simple, the underlying physiology… Read More »
