Well... the thing is, heart rate CORRELATES with burning calories, but it isn't the cause of burning calories. There are a lot of things that can get your heart rate up that don't burn calories, like hormones, being scared or angry, or medical issues. If you think about it, athletes who have very low resting heart rates are probably burning MORE calories at rest than sedentary people with a higher resting heart rate, right?
So I would be hesitant to think that you're burning calories in a sauna just because your heart rate goes up.
