In this modern environment of controlled spaces (air conditioned or heated homes/cars/offices) our bodies get a bit lazy and soon forget how to SWEAT!!
Did you realize that, for the most part, our bodies only have 4 ways to eliminate toxic materials (heavy metals, preservatives, partially hydrogenated oils, food colorings, chlorine, etc, etc, etc) from our bodies: BOWEL MOVEMENTS, URINE, EXHALING and, yes, SWEATING!!
"Give me the power to create a fever and I shall cure any disease" said Hippocrates, Father of Modern Medicine.
If you think about it, almost all of the ancient peoples had "sweating rituals" both for purification of the body as well as the soul. Very powerful stuff.
I am an extreme fan of "infrared" heat for sweating as infrared heats your body from the core out (sort of like microwave ... not really, though) ... the result is that we create a FEVER ... really revving up the circulatory system and the lymphatic system ... revving up the metabolism and burning fat as the body turns on its' fat reserves to create more energy to try to cool the body down.
"They" say that a 30-minute infrared treatment is comparable to a "SIX-TO-NINE MILE RUN" ....
The sweat that your body produces in any infrared sauna-type setting (even my infrared body wrap system) is "SEVEN TIMES MORE CONCENTRATED" with toxic material including cholesterol, sodium, heavy metals, preservatives, food colorings, etc., than any other kind of perspiration you could produce ... Seven times!!!!!!
Something to think about for sure ... get out and SWEAT a little and help your body out a LOT!!
