What Is a Sauna Blanket Insert (and Why You Need One)

Sauna blankets are a great way to enjoy the benefits of a sauna in your home, but they’re not as well-known as the popular spa alternative. Even if you have a sauna blanket, you may not know what a sauna blanket insert is.

A sauna blanket insert is a soft, cotton material used to wrap you in a sauna blanket. Sauna blanket inserts can improve the comfort and longevity of your sauna blanket by creating an easy-to-clean barrier between your skin and the blanket itself. Using an insert allows you to enjoy the comfort of your sauna blanket without wearing clothing.

Read on to learn more about what a sauna blanket insert is and why you should get one.

What do sauna blanket inserts do?

Sauna blankets are great for people who want the benefits of a sauna – if not the whole experience – at home. There are many benefits of using a sauna blanket, but a potential disadvantage is that you need to be almost entirely dressed in light, cotton clothing to avoid getting the interior of the blanket sweaty. That’s where sauna blanket inserts come in.

Sauna blanket inserts are a helpful accessory for your sauna blanket because they allow you to enjoy your sauna blanket without worrying about getting it sweaty and dirty. It slips into your blanket and is easy to remove and clean.

This means that your sauna blanket remains clean and hygienic no matter what you wear in it.

Speaking of, another great attribute of a sauna blanket insert is its great sweat-absorbing capabilities, further maximizing your relaxation time. With this feature, you can sit back and enjoy the heated session without worrying about sweat. Much like going to an authentic sauna and feeling the freedom of “sweating it out.”

Benefits of sauna blanket inserts

Your sauna blanket provides you with almost all of the health benefits of a traditional sauna, but does the sauna blanket insert add any benefits of its own? It does!

Sauna blanket inserts are a great addition to your sauna blanket because of the:

  • Convenience and cleanliness
  • Hypoallergenic material
  • Moisture-wicking qualities
  • Comfort
  • Cleanliness

Let’s look at each of these benefits and how they can improve your sauna blanket experience.


One of the best things about a sauna blanket insert is how low maintenance and durable it is.

After your sauna session, you can simply put the sauna blanket insert in the wash making clean-up easier, and saving you from having to wipe the sauna blanket after each use. 

Hypoallergenic material

Top-quality sauna blanket inserts are made from 100% cotton and are hypoallergenic.

The cotton material is ideal for people with sensitive skin or those who may have respiratory problems, and may reduce any potential reactions to direct skin-to-blanket contact.

In addition, cotton is a centuries-old fabric that has been used for numerous health benefits.

Moisture-wicking qualities

Sweating is one of the main benefits of sauna use; it helps detoxify your body, speeds up recovery, and helps you lose weight. However, most sauna sessions take place in a room where your body is free to sweat.

The sauna blanket insert absorbs the body’s moisture and provides extra comfort without having to wear clothing. 

This means that the insert helps remove the sweat from your body, and protects the sauna blanket.


When using a sauna blanket, a common choice is to wear clothing to protect yourself from the heat.

With a sauna blanket insert, you have the protection and the option of bathing naked in the blanket. And most sauna blanket inserts are made of soft cotton, so it gives you a cozy feeling like you are slipping into a heated cocoon.

Do sauna blanket inserts work?

Sauna blanket inserts are a great accessory for your sauna blanket and provide additional comfort and health benefits.

Sauna blanket inserts are highly functional and are a great alternative to wearing clothes during a sauna blanket heat session. The durability of the cotton provides a nice buffer between you and the sauna blanket and is also very comfortable and easy to clean.

Moreover, you can rely on the health benefits of using a sauna blanket insert. Whether it’s sensitive skin, sore muscles, or stiff joints, a quality sauna blanket insert will help you recover from these ailments. 

Are there risks in using a sauna blanket insert?

Even though this all sounds heavenly, there are a few things to consider when using a sauna blanket insert. 

The sauna blanket insert itself is nothing to worry about. But how you use it together with the sauna blanket is another story.

The function of a sauna blanket insert is to provide comfort and act as a soft capsule you wrap yourself in that complements the sauna blanket.

The addition of the sauna blanket insert also brings a handful of risks, including:

  • Dehydration
  • Suffocation
  • Burns

Let’s look more deeply at the drawbacks of the sauna blanket inserts and how to minimize any risks.


Studies have shown using a sauna blanket cause a lot of sweating, leading to dehydration.

When using a sauna blanket insert, the moisture-wicking features may make you think that you’re not sweating as much and raise the heat to induce more sweating. This can be dangerous if you’re not careful and not sufficiently hydrated. 

Dehydration is a serious medical issue and should not be taken lightly.


It can be a tight fit when you’re wrapped up in a sauna blanket insert along with the weight of the sauna blankets which can weigh up to 20 lbs. 

That being said, do not place your head inside the sauna blanket insert during a heat session. You may be tempted to include the benefits of the heat for your face but it may cause difficulty in breathing and lead to respiratory issues.


In some cases, users have reported burns throughout their bodies from the use of sauna blankets.

A sauna blanket insert helps protect your skin from the excessive heat coming from the sauna blanket. However, this does not mean the blanket itself won’t get toasted if you crank the heat of your sauna blanket.

Also, if left idle, the sauna blanket has the potential to catch fire and the sauna blanket insert would be the first thing to smolder.
