Do cooling pillows actually keep you cool?

They help, but manage your expectations: they slow heat buildup rather than actively chilling you. Gel-infused foam and phase-change covers pull warmth away for a while, and they reheat once they match your body temperature. The most reliable cooling comes from airflow and breathable materials, so latex, shredded foam, and natural fibre covers stay cooler than dense solid memory foam. If you sleep hot, prioritise an open, breathable fill over a marketing label.
