Physical Activity:
The people who have the symptoms of heat rash at their initial level can have the aggravation of heat rash if the person involves more in doing some physical activity. Anything that makes a person heavily, especially if he or she is not wearing the clothes that allow adequate air circulation, then the rashes become intense due to excessive sweat. The excessive amount of sweat production disturbs the sweat gland ducts and further aggravates the symptoms of heat rash.
