Pre-Sleep Temperature Regulation

Meaning

Pre-Sleep Temperature Regulation is the essential physiological process involving the active lowering of core body temperature in the hours immediately preceding the onset of sleep, a necessary step for initiating and maintaining restorative sleep. This reduction is primarily achieved through peripheral vasodilation, which increases heat loss from the extremities. Effective temperature regulation is a key component of the body’s sleep-wake cycle, tightly linked to the circadian rhythm and the secretion of melatonin. Disruption of this thermal gradient, often due to environmental factors or internal metabolic issues, can significantly impair sleep quality and hormonal synchronization.
