Warm to Get Sleepy, Cool to Stay Asleep: The Thermoregulation Paradox of Human Sleep

This research investigates the apparent contradiction between warmth-induced sleepiness and the well-documented benefits of cooler sleeping environments. Drawing on peer-reviewed studies in sleep physiology and thermoregulation, the report examines how temperature influences sleep onset, sleep maintenance, and sleep architecture, translating these findings into a clear explanation accessible to a general audience.
