We learned about it in health class… sweat is the physical evidence that we have a built in air conditioner. Our P.E. teachers seemed determined to push us to sweat in hot gyms and outdoor playgrounds; we were then advised to replenish with liquids so that our system could function properly. And THAT is the extent of what most of us learned about perspiring. In the celebration of ongoing education, it’s time to truly understand the amazing benefits of sweating.
