Swedish sauna as we understand it nowadays was originated in Sweden, where it became popular and was later released worldwide.
Classic Swedish sauna is a closed wooden structure shaped like a cabin. Inside, we find seats located at different heights, so that in the above levels temperature is higher than in the lower levels.
The heat source is inside the sauna and proceeds from stones which in turn are heated by a boiler.
Temperature typically ranges between 60 and 90 degrees Celsius. Water is poured into a container that goes to the stones to give some moisture to the sauna as it is needed. This way the heat does not burn. Approximate ideal humidity is 30%.
