Heat Rash in Infants and Children

What Is Heat Rash?

Skin rashes are a common health issue in many people. They can be painful, uncomfortable, and concerning. Heat rash, also known as miliaria, is one of the most prevalent types of skin rash. It only occurs in humid and hot weather conditions. Both adults and children can be affected when the pores are blocked, making it harder for sweat to escape the body. The main cause is usually frictional properties of the skin surface. Children often have heat rash on the necks and skin folds, while adults tend to experience these spots on the body parts rubbing together, such as under the arms or between their inner thighs. [1]
