What is the Origin of Sleep-Wake Schedule?

This term comes from chronobiology, describing the external manifestation of the body's internal timing mechanisms. Its adherence is crucial for regulating systemic physiological rhythms.

What is the Mechanism of Sleep-Wake Schedule?

The schedule dictates the timing of melatonin secretion from the pineal gland and the subsequent nadir of core body temperature, signaling the body for rest. Proper alignment ensures that anabolic processes, including growth hormone release and cellular repair, occur during the nocturnal phase. Inconsistencies directly impair the feedback loops governing the HPA axis, leading to chronic stress signaling.
