"Myth 7: Sitting in the sauna helps you burn fat.
Truth: Saunas are great for one thing: releasing muscle tension. This is a great way to spend five minutes relaxing after a tough workout. However, sitting in the sauna depletes your body of water and, if these fluids are not replenished, can cause dehydration. It’s important to drink lots of water before and after you sit in the sauna, and while it might be an enjoyable experience
it won’t help you burn fat."

" MYTH: SWEATING IS A GREAT WAY TO LOSE WEIGHT
Remember those rubber workout suits some guys used to sport as they jogged or hit the weights? Just pour yourself in and wait for the fat to melt off, right? The persistence of this view is so great that you can still find variations on no-pain, no-gain infomercials targeting Hispanic cable-television viewers.
The truth: Exaggerated sweat loss does result in weight loss, but at best it's short-lived. Sweating off the pounds can be an unhealthy, even dangerous and potentially fatal way to lighten your load. Body suits, body wraps or any methods that promote profuse sweating (e.g., extreme saunas) do not lead to increased fat loss. In fact:
* More sweating does not amount to more calories burned.
* Sweating is the way your body cools itself off.
* Excessive sweat loss leads to dehydration. Dehydration has a negative effect on strength, endurance, even heart and brain function.
* Tim Scheett, Ph.D., assistant professor in the School of Human Performance at the University of Southern Mississippi, warns that "exercising when dehydrated can lead to heat exhaustion, heat stroke, brain damage and even death."
* Any weight loss that results from sweating will be returned as soon as fluids are consumed.
How to reach your goals: Weight loss can only be accomplished by burning more calories than you take in--sweating techniques have no role to play."

THE MYTH: Sweating facilitates weight loss.
THE TRUTH: Absolutely… If the sweat is exercise induced!
Otherwise, all you're doing is losing water weight. Sweating is astonishingly effective at doing what it was meant to do: cooling the body by glazing the skin with evaporative fluids.
It was never meant to act as a weight loss system. Lose enough water, and you're toying with dehydration. Dehydration or progressive dehydration can occur if you fail to rehydrate yourself sufficiently after every workout. If you get sufficiently dehydrated, your electrolyte balance will get out of whack, your cells will be starved of the fluids they need, and you could die. Not a happy prospect, so avoid it.
For this reason, the old sweatbox and sauna are of no use for losing real weight. Neither are their modern "high-tech" equivalents, such as body wraps and plastic sweat suits, no matter how many people swear by them. All they do is dehydrate you. Yes, you lose weight: two pounds per quart sweated away. But that's weight,
not fat. And the moment you drink enough water, you'll gain all that weight back. Like I have said… “Weight Loss is a LIE!”"
