Overview

Heat rash (also called prickly heat rash) is a red or pink rash. It most often is found on body areas covered by clothing. The rash can form when the sweat ducts become blocked and swell. This often leads to discomfort and itching.

Heat rash is most common in babies. It can happen when a baby is dressed too warmly. But it can happen to any baby in very hot weather. Dress your baby as you would yourself for comfort.

In young children, heat rash often appears on the neck, trunk, or thighs. The rash can be irritated by clothing or scratching. In rare cases, the skin can get infected.

Most heat rashes heal on their own.

How can you care for your child at home?

To help relieve symptoms

• Start by removing or loosening your baby's clothing. Move your child to a cool, shady spot.
• Let the skin air-dry instead of using towels.
• Avoid ointments or other lotions. They can irritate the skin.

To help prevent heat rash

• Dress your child in as few clothes as possible during hot weather.
• Keep your child's skin cool and dry.
• Keep your child's sleeping area cool.
