Cooling Blankets and Breathable Bedding
Overheating is one of the most common — and most fixable — causes of night waking. The fabric science of cooling sheets and blankets, and how to dress your bed for a cool night.
Key takeaways
- Sleep-friendly bedding manages moisture and heat: cotton percale, linen, and bamboo viscose are the leading breathable choices.
- Thread count is overrated; 300–400 cotton percale breathes better than high-thread-count sateen.
- Cooling blankets use moisture-wicking fabrics or phase-change materials that absorb and release body heat.
- Duvet tog (warmth rating) matters more than material — switch to lighter fills seasonally.
- Layer bedding rather than using one heavy piece: easy mid-night adjustments beat wrestling a hot duvet.
