Dry skin

The skin itself is dry and itchy, and exercise accelerates blood circulation and makes the body hot, which may aggravate the itchy situation.

Caused by excessive temperature difference

If you exercise outside in the cold and then enter a warm room, it will cause your skin to itch due to the stimulation of the temperature difference between inside and outside.
