Dry sauna you don’t throw water on the stove. Very lame, as there isn’t much variety in the feeling. It feels like getting into a car that has been sitting in the sun for a few hours.

Wet sauna you throw water on the stove. You can throw more water or less water depending on how hot you want it.

Go for the wet sauna.

when I had a bronchial problem I was advised to sit in a wet (steam) sauna as this would help open up my lungs and help be breath better.
I don’t know if that helps.
