Heat Rash (cont.)

Heat Rash Causes

Heat rash, or prickly heat, is thought to arise from plugging of sweat ducts and hair follicles on the skin. Occluded sweat glands with trapped sweat give rise to the tiny water bumps seen in this condition. Human sweat (with its high salt content) is a very potent skin irritant and may cause skin rashes. It is important to wash off sweat with gentle soap and water.
