No matter what I wear, I don't sweat, is there something medically wrong with me?

Even when you are active? Hypohidrosis or the inability to sweat can be life threatening. You need to be able to sweat to cool off. Hypohidrosis can be caused by many autoimmune diseases. It can also signal that your Autonomic Nervous System is not functioning properly. If you truly do not sweat (meaning that you actually do sweat but just not as much as say a normal person would) you need get yourself checked out.
