What is a Weighted Blanket? 

weighted blanket is a blanket that is made with an inner fill, which gives the blanket its weight. This inner fill can range from glass beads, to sand, to plastic pellets (though plastic is not as common nowadays). Some weighted blankets can be used as is, while others are designed to work as duvet inserts. The main goal of a weighted blanket is to help you feel more relaxed and fall asleep faster. If you want to know more on how weighted blankets work, watch our explanatory video.

How Heavy Should My Weighted Blanket Be?

The ideal size of your weighted blanket will depend on your body weight. A general rule of thumb is to get a blanket that is 10% your body weight, give or take a pound or two. I should note, this is just a recommendation. If you want a heavier blanket, by all means. But if you’re new to weighted blankets, the 10% rule is a great way to start! If you’re still unsure of which size to purchase, check out our calculator for a more specific recommendation!

Can you wash a weighted blanket?

It depends! While some weighted blankets can be washed, not all of them should go in a washing machine. The blanket and fill materials help determine the care requirements, so we recommend checking out the care instructions provided by the manufacturer. If you have a blanket that isn’t fully machine washable, some of them come with outer covers that are.

Do weighted blankets help with anxiety?

Weighted blankets can help to soothe symptoms of anxiety. They simulate deep pressure touch (DPT), which helps to increase serotonin and decrease cortisol levels. DPT is that “hugging sensation” that weighted blankets are known for. Because your body is releasing those “feel good” chemicals, you’ll feel much calmer and relaxed.

Are weighted blankets safe?

Weighted blankets are generally safe for healthy adults. Those with respiratory issues, problems with circulation, sleep apnea, and claustrophobia will want to talk to their doctor before trying out a weighted blanket. Also, weighted blankets are not safe for young children, as most are designed for those above the age of four.

Are weighted blankets bad for circulation?

Those with circulation issues or have conditions that cause this should talk to their doctor before using a weighted blanket. They can be potentially dangerous for those with bad circulation.

Can pregnant women use weighted blankets?

Healthy pregnant women can use weighted blankets safely. If you have any concerns about using a weighted blanket during pregnancy, check with your doctor to confirm that it’s ok for you.

Do weighted blankets make you hot?

Weighted blankets do tend to sleep hot because of their heavy design, fill, and materials used. If you’re a cold sleeper, this is a non-issue. However, if you find yourself kicking off the sheets, weighted blankets might be better for wintertime use. But don’t worry, weighted blankets have come a long way and many of them have cooling features built-in or are designed to allow for more airflow!
