Does sweating more = burning more calories?

I WISH this where true, because then I'd be burning about a million calories a day, ha!  But unfortunately, sweating has nothing to do with weight loss.  It is just your body's way of cooling down from being overheated during exercise.  Think of it this way, there are some extremely obese people who sweat just from walking a short distance or even just sitting in a chair (sad but true) they would be losing weight like crazy!  But, no, it's not true.  Even if you did lose a little bit, it's all water weight and will be gained back when you rehydrate yourself.  So, it's a myth that extra sweating causes you to lose more weight, but don't let that stop you from getting your sweat on!!  :)
