Why does my skin itch when I exercise?

• Answer:

  There could be several reasons: Cholinergic urticaria (hives induced by changes in body temperature). There are cases described of exercise-induced urticaria, which may be cholinergic urticaria. Hives can also be induced by contact with water - aquagenic urticaria. Dermatographism - also an urticarial reaction that is caused by pressure on the skin Your skin may be reacting to your laundry detergent or fabric softener or fragrances as those can irritate the skin, particularly if there is warmth or liquid to make them dissolve better. If there is an existing rash like eczema or psoriasis on the skin, exercise and sweating can irritate the rash and make it more itchy. Swimming in chlorinated water can dry and irritate the skin causing itch, but that usually shows up after not during the activity. It's important to note whether there is any rash that goes along with the itching and how long after exercise, the itching and rash occur. It's also important to note when the onset of the disorder occurred. It's best to consult your dermatologist to get a definitive diagnosis.This answer is not a substitute for professional medical advic...
