Heat rash can occur at any age but is more prevalent in the very young.
The immature sweat glands are blocked and incapable of excreting sweat when exposed to heat. Sweat then becomes trapped in the skin and produces small, red, raised spots. Heat rash will cause the skin to itch and commonly develops in the skin creases or areas where clothing is tight. Heat rash is not serious and alternative medicine is an appropriate first step in treatment. However, if symptoms do not respond to natural therapies, the intervention of a conventional doctor may be necessary.
