9 Tips on How to Stay Cool While Sleeping

When the nights start getting warmer and you wake up feeling hot, sticky, or just plain restless, figuring out how to stay cool while sleeping can make a huge difference. Getting comfortable isn’t just about feeling good, but what helps you actually sleep through the night without constantly tossing the covers off.

A lot of it comes down to your setup. The right bedding, room temperature, and a few small habits can completely change how well you sleep. One brand that’s been getting attention from hot sleepers lately is Rest. Their Evercool line is made with cooling, moisture-wicking fabric that helps air move better around your body, so you stay cool even when it’s warm out.

We’ll go over 9 simple, practical ways to stay cool while sleeping, even when the nights don’t give you much relief.

9 Tips on How to Stay Cool While Sleeping

1. Choose Breathable, Moisture-wicking Bedding

If you tend to wake up hot at night, your sheets might be trapping heat. Cotton often holds onto warmth and sweat, which can make you feel sticky. Try switching to lighter fabrics like bamboo, linen, or the Evercool Cooling Fabric. They let air move around more easily and pull moisture off your skin, so you stay dry and a lot more comfortable through the night.

2. Keep Your Bedroom Cool

Your body cools down when you fall asleep, so the room needs to help with that. Most people sleep better when it’s around 60 to 67 degrees Fahrenheit, or about 15 to 19 degrees Celsius. If you do not have air conditioning, a fan can still help by keeping air moving. Close your blinds during the day to keep the heat out, then open the windows in the evening to let cooler air in. Small changes like that can make it easier to sleep without feeling overheated.

3. Layer Smartly with Lightweight Bedding

A thick blanket might seem comforting, but when the temperature rises, it usually traps more heat than you need. Using a few lighter layers works better. Try starting with a soft, breathable sheet like the Evercool + Cooling Sheets, then add a light quilt or coverlet like the Evercool Cooling Comforter that you can pull off easily if you start feeling too warm. Fabrics like cotton or linen help your body stay at a comfortable temperature since they allow heat and moisture to pass through more easily than synthetic ones.

4. Opt for Light-Colored Bedding

Color actually affects how warm your bed feels. Dark sheets soak up heat during the day, especially if your bed gets a lot of sunlight. Lighter shades like white, cream, or soft blue tend to reflect it, so when you get in at night, the fabric feels cooler. It also gives your room that light, open feeling that just makes it seem fresher overall. 

5. Improve Airflow Under and Around Your Bed

The air around your bed matters more than most people think. If your mattress sits right on the floor or on a solid frame, heat can collect underneath without you realizing it. Raising it even a little, or using a slatted base, helps air move around and keeps things cooler. Some people even point a small fan toward the bottom of the bed to keep air circulating under there, and it really does make a difference.

6. Sleep in Lightweight, Moisture-Wicking Pajamas

What you wear to bed can help more than you’d expect. Heavier fabrics like cotton or synthetics tend to hold on to heat and sweat, which makes it harder to stay comfortable through the night. Lighter, breathable materials, like bamboo, Tencel, or linen, let air flow better and help you stay dry. On especially warm nights, loose-fitting or minimal sleepwear usually feels best since it helps your body cool down naturally.

7. Upgrade to Cooling Pillows and Mattress Toppers

Even if you already use cooling sheets, your pillow or mattress might still be trapping heat. Switching to cooling pillows, like Rest’s Evercool Cooling Pillow, or toppers can make a big difference since they’re designed to pull heat away from your body instead of holding onto it. Materials like gel memory foam or latex usually work best because they’re more breathable. Making small upgrades like these can really change how comfortable your nights feel.

8. Avoid Heavy Meals, Caffeine, and Alcohol Before Bed

What you eat and drink before bed can have a bigger effect on your sleep temperature than you might think. Spicy food, caffeine, and alcohol all raise your body temperature, which makes it harder to fall asleep and stay comfortable. Try to finish eating a couple of hours before bed, and keep it light if you can. Staying hydrated during the day helps too. Just avoid drinking a lot of water right before you sleep so you’re not waking up in the middle of the night.

9. Reduce Humidity and Enhance Ventilation

A room can feel warm even when it’s not, and humidity is usually the reason. When there’s too much moisture in the air, everything feels heavier and stickier. A fan or dehumidifier can help bring that down, and if the air outside is cooler, cracking a window can keep things fresh. If you live somewhere especially humid, bedding made with quick-drying, antimicrobial fabrics helps prevent that clingy feeling and keeps your bed from trapping moisture.

Final Thoughts

Staying cool at night really comes down to a few small habits that make a big difference. Choosing breathable fabrics, keeping your room well-aired, and skipping anything that raises your body temperature before bed can all help you sleep better. The goal is to make your bedroom work with your body’s natural cooling rhythm instead of fighting against it.

If you want an easy place to start, Rest’s Evercool collection is worth a look. Their fabrics balance softness and breathability in a way that really helps hot sleepers get through the night comfortably. With the right bedding and a few thoughtful tweaks, those warm summer nights can feel a lot more refreshing.
