Fair enough to make the comparison perhaps a poor one. However I don't think that people do yoga in saunas, but rather remain seated, correct? The point I'm getting at is: isn't the question "what's the net rise in body temperature?" In hot yoga, the room isn't as hot as a sauna but you're exercising strenuously, so that the body becomes about as hot as you can safely heat a body, kinda like a sauna.
