I just moved into a new apartment and my bathroom has a steam bath built in to the shower (essentially a sauna).
So, I was trying it out and it works as advertised. The shower enclosure got all steamy and hot and I dutifully sweated. However, while cooking myself, I wondered if there was any real benefit to this mild form of torture? Sweating releases mostly water and some salt and I suppose a few other things but is that in any way useful to my body? If I walk out of the shower and drink a bottle of Gatorade I probably put back* whatever I lost in the sauna and then some. Is there a health benefit to doing this or am I just getting to sweat without actually doing any hard work?
[sub] *My brother-in-law (a doctor) told me that the guy who invented Gatorade analyzed the composition of sweat and made a drink that emulated sweat. The theory being it’ll put back whatever you are losing. I do not know if this is true or if he was pulling my leg but his contention is that Gatorade amounts to bottled, synthetic sweat. Yum! [/sub]
