When I got home, I stretched for a second and then jumped in the shower. I couldn’t wait to warm up a little. After about a minute of being in the warm water, I developed patches of red, itchy skin on my belly and legs and it started to burn. What the heck just happened to me? I decided to do some research as to what I was experiencing and how to treat it.
According to an article from Runner’s World, your skin vasoconstricts, which may be just short of getting frostbite. Your skin turns red and burns when your skin is cold and you decide to jump in the shower. The warm water increases blood flow, which in turn allows your body to release chemicals like cytokines and leukotrienes. That is what causes the discomfort. The good news is that this doesn’t actually hurt the skin or blood, but is a harsh reminder to layer up for your next cold weather run.
