SAUNA
In the dry sauna or steam bath, tired muscles become fitter again, lactic acids are broken down faster and it has a positive effect on your endurance. You can start exercising again the next day without any problems!
Sauna
If you can’t tolerate hot humid environments well, the sauna is better. This applies to people with rheumatism or acute infections. Because your heart has to work harder in a steam bath, a sauna is better for people with cardiovascular disease.
Steam bath
If you have respiratory problems and/or allergies, the steam bath is generally the better choice. The moist air helps open your sinuses and airways. Inhaling this steam is also effective against bronchitis, asthma, coughing or other problems that can be remedied with moist air.
Conclusion
The sauna and steam bath are both good for your body and help improve your breathing and circulation. The biggest difference is the temperature and humidity. If you have certain conditions, you should always consult your doctor first for possible dangers.
