If you often wake up sweaty or toss and turn because you’re too warm, you’re not alone. Millions of people struggle with overheating at night — whether due to warm climates, high metabolism, or simply using the wrong bedding. The good news? Cooling bedding can make a major difference in your sleep quality.
In this guide, we’ll break down what to look for in cooling sheets, comforters, and mattresses — and which materials actually live up to the hype.
Why Cooling Bedding Matters
Overheating disrupts your sleep cycles, reduces REM sleep, and can leave you feeling groggy in the morning. High body temperature during the night is one of the most common causes of sleep disruption.
That’s where cooling bedding comes in — it’s designed to:
- Regulate body temperature
- Wick away sweat
- Increase airflow and breathability
- Help you fall asleep faster and stay asleep longer
What to Look for in Cooling Bedding
Here are the key features and materials that actually help you sleep cooler:
1. Breathable, Natural Fabrics
Look for sheets and pillowcases made with natural, breathable fibers. These allow air to circulate and moisture to evaporate, keeping your body temperature stable.
Best options:
- Cotton (especially percale weave) – Light, crisp, and breathable
- Linen – Loosely woven, moisture-wicking, and ideal for hot climates
- Bamboo/Viscose – Ultra-soft, moisture-wicking, and thermoregulating
- Tencel (Lyocell) – Smooth and breathable, with a silky feel
Avoid: Microfiber and polyester. These trap heat and sweat due to their tightly woven synthetic structure.
2. Percale vs. Sateen Weave
If you choose cotton sheets, pay attention to the weave:
- Percale: A plain, grid-like weave that feels crisp and cool. Best for hot sleepers.
- Sateen: A tighter weave with a silky texture. Softer and slightly warmer than percale.
Pro tip: For the coolest feel, go with cotton percale in a thread count between 200 and 300.
3. Moisture-Wicking Technology
Some cooling bedding is engineered with moisture-wicking properties. These sheets pull sweat away from your skin, helping it evaporate quickly.
Look for terms like:
- “Temperature-regulating”
- “Moisture-wicking”
- “Cooling fibers”
- “Phase-change materials (PCM)” – These adapt to your body heat and help maintain a stable temperature
4. Lightweight and Breathable Comforters
If you use a comforter or duvet, choose one that’s labeled lightweight or cooling. Features to look for:
- Fill: Opt for down alternatives, bamboo, or Tencel
- Shell: Choose breathable cotton or bamboo
- Construction: Baffle-box or channel stitching promotes airflow
Avoid: Heavy down or polyester comforters unless labeled as cooling or moisture-wicking.
5. Cooling Mattress Toppers and Protectors
If your mattress sleeps hot, you can add a cooling mattress topper to improve airflow and reduce heat retention. Good options include:
- Gel-infused memory foam – Disperses heat
- Latex foam – Naturally cooler than traditional memory foam
- Copper or graphite-infused foams – Conduct heat away from your body
- Cooling mattress protectors – Add a breathable layer and wick away sweat
Bonus Tips for Staying Cool at Night
- Use a fan or open a window for better airflow
- Sleep with fewer layers – sometimes, a single sheet is enough
- Wear moisture-wicking pajamas or light cotton sleepwear
- Stay hydrated – dehydration can cause overheating
- Shower before bed – a cool rinse can help lower body temperature
