What is Heat Rash?
Heat rash is the generic group name for a number of skin problems that arise or worsen because of heat exposure or overheating. Although most commonly found in babies, it can still occur in all age groups. Common names for heat rash include prickly heat or miliaria. Other heat rashes include heat urticaria (hives) and sweat retention. Heat rash is prevalent in the summer months and particularly in humid climates. The condition usually is self-limited and resolves in hours to a few days without treatment. Rarely, it may be more severe requiring professional medical care.
