Sleep Temperature Science
Night comfort depends on heat release, humidity control, and stable skin microclimate. Pillows matter because head and neck zones are dense heat points.
Cooling pillows are not medical treatment, but they can reduce thermal discomfort. Outcomes are strongest when paired with breathable bedding and correct loft.
| Factor | Impact on Heat Build-Up |
|---|---|
| Dense foam + low airflow | High |
| Breathable cover + vented core | Lower |
| High room humidity | Higher |
| Position mismatch (too much loft) | Higher |
