The 8 Best Cooling Blankets for Hot Sleepers
If you're a hot sleeper, blankets made from cooling materials can improve the quality of sleep you get—but with so many on the market, it can be hard to decide which one to buy. To find the best cooling blankets, we extensively researched the category and dug through testing feedback from hot sleepers on our team, evaluating them on effectiveness, comfort, and durability.
We also interviewed Deborah Young, a textiles expert with more than 25 years of experience in the industry, and learned that the most effective cooling materials are often made from either naturally breathable fabrics that absorb sweat, or manufactured fibers that keep you at a comfortable temperature throughout the night.
Our top pick is the Sleep Number True Temp Blanket, which stands out for its versatility, comfort, and hi-tech design.

How to Shop for Cooling Blankets Like a Pro
Not all cooling blankets are created equal, according to textiles expert Deborah Young. When shopping for a cooling blanket, you should consider the materials or technologies it's made with, whether it's lightweight or heavy, and what kind of care it requires.
Our list includes all types of blankets, including duvet inserts, comforters, weighted blankets, and more. Regular blankets are typically thin and a single layer of fabric, while comforters and duvets are complete with filling for a fluffier look and feel. Some hot sleepers prefer lightweight and thinner blankets—but if you're putting them inside duvet covers, keep in mind that they won't look as fluffy and full as typical comforters. A cooling weighted blanket is much heavier (often anywhere from 10 to 25 pounds) and has all the benefits of a traditional weighted blanket, but is made with cooling materials.
Cooling blankets are typically made from plant-based materials. These natural materials have moisture-wicking capabilities that give them a cooling effect. Examples of these materials commonly found in bedding are linen, bamboo, cotton, and Tencel (which is made from wood pulp, typically from eucalyptus trees).
An alternative to naturally cooling materials, manufactured fibers are also good to watch out for. While synthetic materials like polyester are usually known for trapping heat, there are now many materials made with polyester that are infused with temperature-regulating technology. These materials can be very effective at cooling because they work instantly, according to Young. Look for blankets that use technologies like 37.5 and Outlast, which absorb heat to keep your body at a comfortable temperature.
If you'd rather not go to the dry cleaners, we suggest looking for a blanket that's machine-washable. You can also find a comforter or quilt that's compatible with a duvet cover (meaning it has built-in loops or ties) or comes with its own breathable cover. Duvet covers are much easier to wash than an entire blanket, and using one means you won't have to wash the insert as often.
Questions You Might Ask
How does a cooling blanket work?
Cooling blankets made of cellulose fibers (like linen) are absorbent, so they wick away moisture to cool you down. Blankets with synthetic materials can absorb and release heat as needed, and they can work much faster. Some blankets are made with cool-to-the-touch fabrics for instant relief that's not as noticeable after a while on your skin, while others have a less obvious effect that constantly keeps your body at a comfortable temperature all night.
How and how often should you wash a cooling blanket?
Every product is different, so you should always check the care instructions for your specific blanket. Many machine-washable options recommend using cold water and either drying on low heat or air drying. You should wash your blanket a few times a year, but you can extend the time between washes by using a duvet cover you can wash regularly.

Should you choose a natural fiber or a lab-made fiber?
That depends on your preference! Some people just prefer to have bedding made of natural materials like cotton or linen, while others who want the latest and greatest in cooling products might lean toward lab-made fibers.
