Most people think of prickly heat as an annoying symptom of hot, humid summers. But overdressed youngsters are prone to it in winter, too.
Symptoms of prickly heat are itching, irritations, small blisters, and large, red areas on the skin, appearing mostly on the thighs and torso, the Loyola University Health System says.
The condition is caused by pools of sweat that are trapped beneath the skin. Avoid prickly heat by keeping the skin cool and dry. Your doctor may also prescribe a corticosteroid lotion.
