A steam sauna differs from a traditional dry sauna in that it relies on a steam generator to heat water to boiling point, releasing a large amount of steam, quickly creating a high-temperature, high-humidity environment within a confined space. A steam generator is essentially an electric heating device.

It is completely safe to use outdoor steam sauna rooms in winter. The prerequisites are: 1. The equipment is properly designed and in good operating condition; 2. Time, temperature, and physical condition are strictly controlled during use; 3. Comprehensive warming measures are in place when leaving the room; 4. Special groups should use the equipment under medical advice or avoid use; 5. Maintenance and cold-weather protection measures are in place.
