Do saunas and steam rooms really help aid weight loss?

Found this on google...

What a Sauna does is it raises your body temperature and causes you to sweat. that sweating is great for cleaning out pores as well as relaxation. It also causes your body to go into something called "overdrive". When your body is in this state it kick starts your metobolism. sort of like a defibulator kickstarts your heart. It raises your temperature and your body automatically tries to cool it down. Since you are in a superheated room, your body will not successfully lower your body temperature but will continue to try, this burns calories. Just like when you run on a treadmill, you burn calories by an excellorated heart rate as well as the body trying to cool itself down. Do I suggest a sauna or steam room is the main sorce of weight loss, no. You lose weight much faster by a healthy diet and excercise plan, but a steam room helps that proccess.

Yeah, that whole thing sounds like BS to me.
Also, a defibrillator doesn't stop OR start the heart, it passes a current calculated to eliminate irregular patterns where the ventricles are not 'beating' in correct synchronisation. That is known as ventricular fibrillation, hence DEfibrillator.
