What's New - Prickly Heat   Prickly Heat   Also known as heat rash, or miliaria, prickly heat is an itchy and red skin rash which often causes a stinging, or prickling, sensation. It often occurs when you sweat more than usual, which is usually due to a hot or humid climate. Babies and children are more likely to be affected by prickly heat than adults because their sweat glands are underdeveloped. Prickly heat is not a serious condition, and rarely requires any specific treatment. Most prickly heat rashes will heal within a few days. Treatment • Keeping out of the sun will help, as will cool loose cotton clothing and regular tepid baths or showers to cool the skin. • Calamine lotion will help with the itching. • A baby or child who is unwell with a rash should be assessed by a Doctor.     Return To Previous Page
