This skin rash is usually accompanied by itching and burning. It is caused by an obstruction of the sweat ducts so that perspiration does not reach the surface of the skin, but backs up and causes pimples the size of a pinhead. If the obstruction is superficial, the pimples are white, if it deeper they are red. The condition can be brought on by other minor skin irritations by continued exposure to moist heat such as a compress or by exercise in humid weather. Infants and people who are overweight are especially prone to prickly heat.
The discomfort can be eased by wearing lightweight, loose fitting clothing, especially at night, and keeping room temperature low. Alcoholic beverages, which tend to dehydrate the body, should be avoided. Tepid baths and the application of cornstarch to the affected skin areas will unusually relieve itching. If the rash remains for several days a doctor should be consulted to make sure it does not arise from some other cause.
