Do you think there are benefits to sweating it out in a Sauna? Or is it all a bunch of hype? I'm in a weight loss competition, and have added trips to the sauna just to rid my body of any extra fluid retention (being a female, that does happen!), and because it just feels awesome. BUT, not sure if it really helps? Or does it basically dehydrate oneself? Thoughts, ideas? Do you Sauna, or not?
