How Cooling Pillows Work
Cooling pillows work through three mechanisms: heat conduction away from skin, airflow through core materials, and moisture evaporation at the cover.
The strongest models combine all three. Examples include Coop Eden review, Purple Harmony review, and Tempur-Cloud Breeze review.
| Mechanism | What Helps | Common Failure |
|---|---|---|
| Conduction | Gel, PCM, latex interfaces | Rapid warm-up without release |
| Airflow | Perforation, shredded fill | Dense core heat trapping |
| Moisture handling | Breathable covers | Damp surface retention |
