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.

My goal time? My goal is to enjoy the time I spend running.
I had brought up this same question in another thread. I wonder if a good gauge similar to Bodybugg or a Polar F6 heart monitor be helpful in determining if calories are burned? I don't have either but plan on purchasing Polar F6. One of the members in the Biggest Loser forum indicates she has one and likes it. When I get one I will check it out in the sauna.
I am looking to find CREDIBLE information about Calories Burned using the Sauna. There are TONS of conflicting opinions... (everybody's got 'em and they all stink!!) The Water weight theory... well DUH!! of COURSE immediate scale dropping is water weight (fighters and wrestlers know this WELL). doesn't mean that water weight is the ONLY thing going on.
speeding up metabolism...?? very difficult to demonstrate conclusively. if you can't prove it, then you can't disprove it.... (and i could sell you some metabolic diet pills).
Burning Calories...??? THIS is where i'm interested. I checked my heart rate sitting in the sauna tonight. 150bpm!!!! sitting still and breathing!! since the definition of aerobic work is burning oxygen, 150bpm stands to reason to have some aerobic effect.... (??). ** i have good calorie burned calculator based on heart rate, but hesitate to attribute like for like calorie burn sauna vs. intense aerobic work... some 'opinions' claim up to 600 calories per hour from sauna (about half of high intensity aerobic work)..
