Mostly from drying: There is that histamine release in people who exercise for the first time after prolonged time of not doing it. This opens up the blood vessels to allow evaporation and get rid of the heat. The histamine is an allergy component that allows other same chemicals to be released and cause itching but the drying and evaporation also causes the itching effect.
