Thermal Regulation Timing

Meaning

Thermal Regulation Timing refers to the precise, circadian-controlled lowering of the core body temperature, which is a critical physiological prerequisite for the initiation and maintenance of sleep. This timed drop in temperature, typically achieved by diverting heat to the extremities, acts as a potent signal to the brain’s sleep centers, facilitating the onset of nocturnal rest. The accuracy of this timing is a powerful indicator of a robust circadian rhythm and sleep propensity. Disruption, such as an elevated core temperature too close to bedtime, is a common cause of insomnia and fragmented sleep.
