Are Weighted Blankets Hot?

You've heard about all of the sleep benefits you can get from using a weighted blanket. While they sound calming and snuggly, you wonder, “Are weighted blankets hot to sleep under?”

You don’t want to choose between sleeping cool and getting the deep pressure stimulation-of a weighted blanket. Luckily, you don’t have to. In this article, we’ll show you how a heavy blanket’s materials affect your sleeping temperature and other steps to avoid overheating at night.

How Overheating Affects Sleep

Maintaining a cooler body temperature supports sleep. After all, when our bodies cool down at night, it tells the brain it’s time to go to sleep. This study from the National Center for Biotechnology Information explains insomnia symptoms that correlate with body temperature rhythm abnormalities. Another article in the National Center for Biotechnology Information shows that the core body temperature of insomniacs is significantly higher than for those who regularly get enough restful sleep. 

If you’re too warm at night, falling asleep won’t be your only challenge. You might even wake up during the night and sleep restlessly throughout the night.  

Maybe your blanket traps too much body heat, or perhaps your natural temperature that makes you overheat at night. Some people just run warmer or have periods of higher temperatures, like women who are perimenopausal and having hot flashes. Being under the weather or living in a warmer climate could make your nighttime temperature higher too.

Now that you know why it’s important to keep your body temperature at a comfortable level before and during sleep, let’s answer the question “Are weighted blankets hot?”

Are Weighted Blankets Hot To Sleep Under?

While weighted blankets are heavy by definition, they’re not necessarily hotter than an average blanket. Unlike an electric heated blanket, weighted blankets don’t have heat settings or any way to generate heat. There are no heat settings or shut-off buttons like a heating blanket has, so you'll want to choose a blanket that can balance your body heat and keep you comfortable. The fabric and filler of your weighted blanket determine whether or not the blanket creates and traps too much heat. So, are weighted blankets hot? That depends on the material and filler they use.

Many weighted blankets on the market use warmer fabrics and poor-quality materials, which hot sleepers should avoid. Let’s look at how to identify which fabrics lead to comfortable sleep and which lead to overheating.


The number one factor that can contribute to a hot blanket is its outer fabric. Look for a comfortable and breathable material. 

For a cozy yet breathable blanket cover, look to a super soft  Minky, Tencel, or Lyocell fabric. They are soft and luxurious but still allow the right level of airflow to keep you comfortable. Other warmer but still breathable fabrics are sherpa and a soft micromink. 

You also could choose a bamboo or organic cotton cover. The natural materials pull moisture away from your body, which keeps you from experiencing night sweats in the middle of the night. They have higher breathability, which helps them give you better sleep.


The filler material can also determine if weighted blankets are hot. The filler will also dictate your comfort level. Micro glass beads are small enough to conform to your body as they hug your shape and soothe you as you rest. The micro glass beads also allow for better airflow, which helps keep you more comfortable.

On the other hand, fillers like poly pellets trap body heat and restrict airflow. With this type of plastic pellet filler, your body heat builds and you wake up from being too hot.

Weighted Blanket Materials to Avoid

Some people wonder “Are weighted blankets hot for hot sleepers?” If you're a hot sleeper, avoid weighted blankets with a polyester base fabric at all costs. Not only are these water-resistant fabrics don’t allow your sweat and heat to escape. Unlike fabrics like mink, they aren’t breathable. 

Polyester fabrics will retain your heat and will keep the moisture from your body close to you. It will lead to overheating, and you'll feel sticky and uncomfortable with your damp, sweaty skin.  Neither of these situations will help you get better sleep.  

Best Weighted Blanket Materials for Hot Sleepers

Look for moisture-wicking and naturally breathable materials like microfiber, bamboo, and cotton. (Bonus: Each of these materials is super-soft.) They are known for their comfort and breathability, which can help your body regulate your temperature while you sleep. Also, the moisture-wicking properties of these fabrics keep you cool and comfortable by moving the sweat away from your skin.

You can also use a weighted cooling blanket. These blankets are designed with premium fabrics and fillers that work to keep your body temperature regulated.  You can even remove the outer cooling layer if you need to bundle up on a chilly fall night. The best cooling weighted blankets are still a high enough percent of your body weight to lull you into a deep and restful sleep. 

With a cooling blanket, you don’t have to choose between sleeping cool and receiving all the relaxing benefits of weighted blankets.

Are Weighted Blankets Hot for Kids?

If you’re purchasing a weighted blanket for your child, you might be wondering “Are weighted blankets hot for kids?” — especially if they have autism combined with sensory issues that cause them to be hyper-sensitive to changes in touch or physical comfort. 

One easy fix is to purchase a weighted blanket with a removable cover. You can start by having your child sleep under just the inner weighted blanket first. Then, when they sleep through the night for a few nights in a row, they can graduate to sleeping with the entire blanket (covers and all).

You’ll also want to purchase a weighted blanket that’s made specifically for kids. An adult weighted blanket will be too heavy for a child. The blanket should be around 10% of your child’s body weight. Additionally, most children’s weighted blankets are 36x48 inches. They're the perfect way to help children between 40 to 70 pounds enjoy relaxing, comfortable sleep. 

How To Stay Cool Throughout The Night

The answer to the question “Are weighted blankets hot?” may be no, but if your bedroom and bed are hot, you still may not sleep well. Keep your bedroom anywhere from 60 to 67 degrees Fahrenheit for optimal sleep. If you can turn on an air conditioner or fan to keep the temperature low, you'll feel more comfortable. 

Your medications, pajamas, and even your mattress could also make you warmer during the night. Making sure you’re setting yourself up for sleep success with these bedroom factors will make comfortable sleep easier. 

Once your bedroom is at the right ambient temperature and your clothing and mattress are not too warm, a blanket that is made of breathable fabric will give you the pressure you need to relax and help you sleep comfortably through the night.
