Artificial fiber clothing do not allow the body to breath. You must realize, the skin needs air. It needs circulation. Then you sweat. The artificial fiber clothing is made from an assortment of chemicals.
Nylons are the biggest culprit, for making the body miserable.
Women get yeast infections. Because the body was not breathing. You may as well wrap your body in plastic wrap. It is the same feeling to the body. I am not knocking the plastic industry, but there is a place for plastic, and it is NOT on the human body.
