If my hands and feet are sweating, but I put cotton socks on, my feet either stop sweating completely or significantly reduce sweating. Then my hands follow and stop. If I wear sandals or anything that makes me feet sweat, my hands start sweating. It’s the strangest thing. What does my feet have to do with my hands?? I definitely sweat a lot more in the summer. My hands and feet are bone dry in the winter. I think it’s humidity that triggers my hyper hidrosis. But why are the two connected?
