Skin irritation (redness) due to excess of friction
Redness of the skin due to excess of friction leads to increased pain awareness. The pain can severely interrupt the comfort. The most frequent protocol is after-care: treating a blister for days following activity to promote healing and protect against continued skin damage.
Skin irritation due to friction is frequently seen when wearing new shoes. When surfaces in contact ( f.e. a shoes and a human skin ) move relative to each other, the friction between the two surfaces converts kinetic energy into heat. This heat leads to degradation of the different epidermal layers. The skin becomes warm and irritated and soon a blister or superficial burn will appear.
