Prickly heat, or heat rash, is a harmless but very itchy skin rash with small red spots all over the affected areas. It is common in Australia in hot and humid areas.
The rash is caused by a blockage and inflammation of sweat ducts during times of exposure to heat and high humidity. These blocked sweat ducts cause sweat to escape into adjacent tissue thus producing the itching and prickling sensations associated with the condition.
Treating heat rash is simple and usually does not require medical assistance. Other heat-related problems can be much more severe.
