What causes heat rash?

ANSWER

You can get a heat rash when you sweat too much. The ducts from the sweat glands in your skin become blocked. This causes the sweat to leak into the surrounding tissue, which leads to irritation and redness. You may feel the prickly, or stinging, sensation that gives this condition its name.
