Your mattress, bed sheets, and comforter can all make you sweat too much at night. If you’ve narrowed the culprit down to your comforter, here are some tips on what you can do to reduce night sweats and sleep better. These range from free solutions to getting a new cooler comforter. 

Why Does My Comforter Cause Night Sweats?

Your comforter is making you sweat because it’s overly warm. Of course, you want a comforter that’s toasty and warm. But if it’s too thick or made from less breathable materials, it will trap heat and make you overheat. 

Comforters made from synthetic materials like microfiber (down alternative) and polyester are more likely to make you hot and sweaty. That’s because these materials don't have good airflow, so heat given off by your body gets trapped under the duvet. 

You could also be using a comforter that’s designed for the colder months of winter and fall. It will be thicker and denser than a spring or summer comforter. 

5 Solutions if Your Comforter is Too Hot 

Here’s what you can do if your comforter feels too hot and is giving you night sweats. 

1. Get a Cooler Comforter 

The easiest solution is to simply switch the comforter for one that’s lighter and cooler. But this would mean spending money on a new comforter if you don't have a cooler one at home. 

If you don't mind getting a new comfort, make sure you pick the right one. Look for one designed either for all seasons or spring and summer. Our very own Jax comforter for men is a great pick. 

If you are a naturally hot sleeper or you sweat a lot at night, we recommend a summer comforter or duvet as it will be extra-cool. Wool and down comforters are also great at cooling, thanks to their breathable natural materials. 

2. Pair it With Cooler Sheets

If you cannot replace the comforter, you can try cooling down the bed instead. One of the ways to do this is by using cooler sheets made from breathable fabrics like cotton, bamboo, Tencel, linen or silk. 

These sheets improve heat dissipation away from the bed, which will help counter the hot comforter. Most breathable bed sheets are also good at wicking away sweat. 

You can also decide to go all the way and replace the mattress itself with a cooler one. Some mattresses, particularly those made from memory foam, trap heat and can make a hot comforter even more uncomfortable. 

Switching to a hybrid or latex mattress can help you sleep cooler. 

3. Get a Bed Cooling System 

Another option is to keep all your bedding, comforter and all, but get a bed cooling system. There are two main types: passive and active. 

Passive cooling systems include cooling mattress toppers and pads. These can help if your overheating and sweating problem is not too severe. Toppers and pads made from natural materials like latex, down, and wool offer the best cooling performance. 

Active cooling systems offer much more powerful cooling. Some like BedJet blow cooled air under the sheets while others like ChiliPad by Sleepme run chilled water through a mattress pad. With these systems, you can even set your preferred temperature. 

4. Remove the Duvet Cover

The problem might not be your comforter but the duvet cover. You could have a cool and breathable comforter that’s ruined by a duvet cover that traps heat. 

So before you spring for a new comforter or buy an expensive bed cooling system, take the duvet cover off the comforter and see how it feels. If you feel cooler and sweat less, then you know the problem is the cover. 

We don't recommend leaving the comforter uncovered unless you want to turn it into a home for allergens, dirt, bacteria and fungi. 

5. Lower the Bedroom Temperature  

If you’d rather not change anything about your bed, the next best option is to make the entire bedroom cooler. 

You can turn down the thermostat, turn on the fan to improve air circulation or install a window or portable air conditioner to cool just the bedroom. 

Cooling the bedroom can help as it allows more heat to escape from the bed. Heat always flows from a warmer to cooler area.
