Evidence Strength
5/5 — Very StrongVery strong evidence. Core body temperature drop is one of the primary physiological triggers for sleep. Replicated across many studies.
Overview
Test a cooler bedroom and optional warm shower 1-2 hours before bed as environmental cues that may support sleep onset for some people. Adjust the target temperature around comfort, safety, housing constraints, and caregiving needs.
Wellness education and routine support only. Review the evidence, caveats, and interactions before trying this protocol, and ask a clinician when medical conditions, pregnancy, medications, or symptoms are involved.
How To Do It
- 1
Set bedroom temperature
Set thermostat to 65-68°F (18-20°C). Use a fan if no AC.
- 2
Take a warm shower
1-2 hours before bed, take a warm (not hot) shower for 10 min. The post-shower cooling triggers vasodilation and core temp drop.
- 3
Choose breathable bedding
Use moisture-wicking sheets and avoid heavy synthetic comforters.
- 4
Keep feet and hands exposed
Extremity vasodilation helps dump core heat. Let feet stick out from covers if comfortable.
The Evidence
