Heat Can Wake You Up, and Your Sheets Can Trap It Against Your Skin

A bed with a hot side and a cool side

Your body gives off heat all night. Whether that heat escapes or builds up depends a lot on the fabric wrapped around you.

Polyester and microfiber are plastic fibers, and plastic doesn't breathe. Densely woven high thread-count cotton lets less air through. Either way, heat has less room to escape, so it builds up right there against your skin.

The Fixes You've Tried Cool the Room, Not the Bed

Nightstand with a fan, AC remote and cooling pad

Fans and a lower thermostat work on the air around you. Neither one changes the fabric touching your skin all night, which may be why you still wake up hot.

Thread count is a trickMore threads means a denser weave, and a denser weave lets less air through.
Polyester is PETThe same plastic family as a water bottle, spun into a fiber.

Based on Your Answers, 100% Bamboo Viscose Sheets Could Make a Real Difference for You

Cosy House 100% Bamboo Viscose bed sheets

Hollow Fiber. Heat Out. Cool to the Touch.

Solid plastic fiber vs hollow 100% Bamboo Viscose fiber

Each 100% Bamboo Viscose fiber is hollow, like thousands of tiny straws. Body heat passes through the sheet instead of getting trapped under you, and moisture wicks away instead of soaking in.

It's structural, not a coating. 9/10 hot sleepers said they slept cooler in just 1 night.*

*Based on an independent survey conducted in 2026 (n=5,000).
