The Cooling Bedding Guide
Fabric science over marketing gimmicks — the real ways to make your bed cooler at night.
Start with the fibers
Breathability comes from the material itself. Long-staple cotton percale, viscose from bamboo, and Tencel lyocell all move heat and moisture. Dense synthetics and polyester blends trap them.
Weave matters more than thread count
Percale is a plain, one-over-one weave — crisp, matte, cool to the touch. Sateen is smoother but slightly warmer. Very high thread counts usually mean a heavier, warmer sheet — not a better one.
Layer light
Instead of one thick comforter, layer a lightweight quilt or coverlet with a breathable sheet. That way you can easily kick off a layer if you overheat mid-night.
Cool your room
Even the best bedding can't compensate for a hot bedroom. Aim for 65–68°F. A quiet fan moving air across your bed makes a bigger difference than most cooling gadgets.
Care to keep it cool
Wash cold and skip fabric softener. Softeners coat fibers with waxy residue that reduces breathability over time.
