Heat rash, also known as prickly heat, can affect people of every age but is most common in infants and small children, who are often less capable of regulating their body temperature and are at the mercy of others to dress them appropriately for the weather and keep them in comfortable conditions. Once your child is old enough to remove their jacket and let their caregiver know they are hot, the risk diminishes. When older children and adults do develop the condition, it is often while competing or training for an athletic event or playing hard in the heat of the day.


1. What is heat rash?

If you notice small red bumps on your child’s skin, they may have a heat rash. It can appear anywhere, but it develops most often in the skin folds and on the buttocks and neck. You can typically treat heat rash at home, but understanding a little more about the condition allows you to recognize when there may be a problem.
