Over 13 000 people in the US search for this every month. So does sitting in the sauna burn calories? Here's the short answer: Yes sitting in the sauna makes your body burn calories at around 1.5 times the normal rate. However, thinking that you can lose weight by just sitting in the sauna would be absurd. The weight you lose in the sauna is mostly water that you sweat out of your body and it's important to stay hydrated and replace it during the sauna session. The biggest benefits of regularly going to the sauna are far and beyond losing weight.
So where is all this talk about losing calories in the sauna coming from? What actually happens in your body that could cause you to burn more calories? Is there any evidence that supports this claim?

Traditional saunas on the other hand make yous sweat more, which might be better for removing toxins from your body.
In the end, we suggest you don't select your sauna type based on how many calories you're going to burn in a sauna. That is because the difference between sitting in traditional, steam, or infrared sauna has not been researched enough in order to tell the difference between each one when it comes to helping you lose weight.

It's good to end this article with some exact numbers on calorie burn. According to sauna manufacturers, you can expect to burn 1.5 and 2 x the number of calories you normally burn by sitting on the sofa. So in a 30-minute sauna session, this means 62-200 calories depending on your size, weight, and age. Eventhough soime sources claim that 30-minute sauna session burns even 300 to 1000 calories, we simply say this is not true.
Sauna use is a great way to relax and become healthier. Remember to consult your doctor if you have any medical conditions before
