Saunas are great for stress relief and relaxation, but many believe that it can also help you lose weight because since your body temperature is elevated your heart pumps faster meaning you’ll burn more calories. Some believe that in a 30 minute sauna session you can burn anywhere from 300 to upwards of 1000 calories !
However, as amazing as that sounds there isn’t any proof or valid research to show this and if you know anything about cardio then you already know it takes much longer than 30 minutes to even burn 300 calories in one session. So how would it be possible to just sit in a hot room for 30 minutes and burn even more than 300 calories ?… You can’t and it’s as simple as that.
How Much Weight You’ll Actually Lose In The Sauna
Although you won’t burn anywhere near 300 calories by just sitting in the sauna you will still lose weight, 3 – 5 pounds of mostly water weight and this is because you’ll be sweating profusely. When you sweat so much your weight will decrease rapidly, but losing this water weight is not permanent and once you drink or eat something that lost weight will be gained back almost instantly.
That being said it’s still possible to burn calories while sitting in the sauna, around 20 – 50 calories in a 30 minute session because increasing your body heat causes your metabolic rate to increase by up to 20% and heart to beat around 30% faster. It’s also extremely important to remember that sitting is the sauna for any longer than 35-40 minutes will lead to severe dehydration, making it much harder for you to lose actual body fat since being hydrated keeps you fuller for longer so that you eat less. In some extreme cases excessive sweating can cause a heatstroke, kidney damage or even death due to the severe loss of electrolytes.
The Benefits Of Using A Sauna
- Detoxification – When you sweat the toxins in your lymphatic system will be removed, detoxifying your body.
- Faster Recovery – Saunas can help relieve muscle pains so that you’ll be ready to workout again in no time.
- Reduces Stress – Sitting in a sauna is very relaxing so it reduces stress.
- Can Aid In Fat Loss – Since your metabolic rate is increased you will be able to burn calories for up to several hours after using the sauna.
To sum up sitting in the sauna alone won’t help you build muscle or burn any fat, but combining it with a proper nutrition plan and workout routine will. So if you do decide to use the sauna at your gym make sure you drink around 2-4 glasses of water after and to leave upon feeling dizzy or ill.
