What is a Heat Rash (Prickly Heat)?
Heat rash or prickly heat is an uncomfortable skin irritation in hot and humid climates. The medical name for heat rash is miliaria.

A rash can be in the form of tiny blisters or pimples. People who sweat more or are living in a humid climate are likely to have heat rash on their skin. Also, children and babies are more prone to it as their sweat glands are in the developing stage.
