Many people reach for melatonin when sleep becomes difficult. For most adults, however, the body already produces its own. What often matters more is a physiological signal that is frequently overlooked: core body temperature.
Sleep onset is triggered when the brain senses a drop in internal temperature of about 1–2°C. This process is tightly regulated by the circadian rhythm and acts as a natural cue for the nervous system to slow down.
A simple framework clinicians often explain is the Core Temperature Protocol:
1. Warm shower before bed
Heat dilates surface blood vessels, allowing excess warmth to leave the body once you step out.
2. Cool, well-ventilated bedroom
A slight temperature drop signals the brain that it is safe to enter sleep mode.
3. Feet slightly uncovered
This helps excess heat dissipate more efficiently, supporting faster sleep onset.
These steps support the body’s natural sleep mechanisms without relying on external hormones. They are gentle, practical, and grounded in thermoregulation science.
