A weighted blanket is a heavy blanket that is meant to have a calming effect on the body when you go to sleep. Weighted blankets have grown in popularity in recent years as a form of therapy. They can mimic the feeling of a hug — causing a surge of feel-good hormones like oxytocin and serotonin.

Weighted blankets are also called “anxiety blankets” because of the calming effects they can have on those that experience sleep anxiety and other sleep disorders. They can help a variety of different people who experience any of the below symptoms:

  • PTSD
  • Anxiety
  • Insomnia
  • ADHD
  • Restless leg syndrome
  • Depression
  • Autism

Weighted blankets come in a variety of weights from five to 30 pounds. You may be wondering, how heavy should a weighted blanket be?

We recommend choosing a weighted blanket that is 10 percent of your body weight for optimal comfort. For more information on how to choose the perfect weighted blanket for you, read our buying guide below.

What if you fall between two weight recommendations? Many experts recommend rounding up and adding one to two pounds. One study found that more than 10 percent of your body weight can actually be quite calming. However, it’s always best to use your best judgment and choose your personal preference.

As you get older, your age can cause problems with your sleep.

Can a Weighted Blanket be Too Heavy?

Yes, a weighted blanket can be too heavy if you don’t get the correct size. Weighted blankets that are 35 pounds and over should generally be avoided. If you feel like you can’t move under your blanket, look for one that is lighter.

What About Height?

Height doesn’t play as large of a role as your body weight does in what weight of blanket you should get. It matters more for determining overall size. Just like when choosing the size of your bed, you’ll want a blanket that will work for your height.

If you’re over six feet tall, a twin-sized blanket will likely be too small for you. If you’re on the shorter side, a king-sized blanket would likely be too heavy for you. A good rule of thumb is to choose a weighted blanket that is the same size as you or slightly larger. You want a weighted blanket that will cover your entire body.

How to Choose a Weighted Blanket: General Guidelines

If you can, it’s important to choose a weighted blanket that is 10 percent of your body weight or one to two pounds heavier. This ensures you’re getting the most out of your blanket and experiencing the deep touch pressure that will leave you calm and relaxed.

It’s important to note that if you’re someone that sleeps hot, a weighted blanket will likely make you sleep even hotter. If you can, look for one that has moisture-wicking properties and find other creative ways to stay cool at night.

Weighted blankets have a plethora of benefits that can keep you calm and relaxed while falling asleep. If you’re someone who experiences anxiety, restless leg syndrome, or insomnia, or you just love to be as snug as a bug in a rug, then you’ll likely love the effects of a weighted blanket.
