Overview
Core body temperature falls as you fall asleep and stays low through the deepest part of the night. A warm bedroom works against that drop; a cool room and a cooler bed surface work with it. This protocol sets a fixed evening room temperature, cools the bed at sleep onset, and warms it slightly before waking. The numbers below are starting points, not prescriptions — thermal comfort varies widely, so adjust in small steps and judge by how you feel and what your sleep data shows over weeks.
