Similar to above posts but I came here to say how much saunas give me the vom. Or the idea of them anyway, I can't enter one myself lol. Recently joined the gym and keep being told how a sauna is great for recovery. But I cannot get my head around how someone can sit in a room thick with other people's sweat soup evaporating and filling the entire room?! 
Don't fancy inhaling deep breaths of condensed man tit sweat thanks
I'd rather be sore the extra day or two!
