What Scientific Studies Support the Therapeutic Claims of Infrared Saunas?

You’ve probably heard that infrared saunas can be good for your heart, skin, muscles, and mood. But how much of that is backed by science? While research is still growing, several studies show that infrared heat can have real benefits when used regularly.

Let’s learn more about infrared saunas and look at what scientists have found so far.

What Is an Infrared Sauna?

An infrared sauna uses infrared light to heat your body directly rather than heating the air. This allows your body to warm up from the inside, which can make you sweat at lower temperatures. Some people find this more comfortable, while others prefer the deeper heat of a traditional sauna. Both types can be beneficial. It’s more about personal preference.

 
What the Research Says About Heart and Circulation Health

There’s some evidence that heat therapy can benefit the heart, circulation and blood pressure.

• One review found that people who use saunas regularly have lower rates of high blood pressure, cardiovascular disease, and stroke.

• Other evidence supports that infrared saunas can help with blood pressure and heart failure.
   

Even better? Saunas help you relax. The more relaxed you are the better you’ll feel overall!

 
What About Pain, Musculoskeletal and Inflammation?

Researches have found that infrared‐heat therapies can help with pain, stiffness, inflammation, and recovery.

• One review found infrared therapies showed “significant potential” for reducing musculoskeletal pain. Conditions like fibromyalgia and osteoarthritis were talked about in this study.

• More recently, a review of sauna therapy in rheumatic diseases found benefits like reduced pain, reduced stiffness and improved mobility.

• In general, saunas are also popular for muscle recovery after exercise.

What About Safety?

 Infrared saunas are generally safe for most healthy adults. People with heart conditions, low blood pressure, or other medical concerns should talk to a doctor first. Pregnant women should avoid infrared sauna use unless approved by their healthcare provider.

Always drink plenty of water before and after each session. Limit your time at first and gradually increase it as your body adjusts. Avoid using a sauna if you feel dizzy, lightheaded, or dehydrated.

What’s Still Unknown?

Researchers are still learning about infrared saunas. Most studies are small and short-term, so there’s no official guideline for how often or how long to use one. It’s also unclear whether infrared heat works better than traditional saunas for specific health goals. Both types raise body temperature and heart rate, so their benefits likely overlap.

Key Takeaways From the Studies
