Heat boils, also known as prickly heat or miliaria, are a common skin condition that occurs when sweat ducts become blocked and sweat accumulates under the skin. This can lead to the formation of small, itchy, and red bumps. Heat boils are most common in hot and humid climates and can affect people of all ages, but they are especially common in infants and young children.
Heat boils are usually not serious, but they can be uncomfortable and itchy. In most cases, heat boils will clear up on their own within a few days. However, there are a number of things that you can do to help prevent and treat heat boils.
