Signs and Symptoms
Heat rash can occur after exposure to hot conditions. There can be many small, red bumps all over the body, usually occurring in highest concentration in covered areas where there is a lot of friction, such as the neck, chest, and body folds. The face, palms, and soles are generally not affected. Heat rash can cause intense itching and stinging, which can become worsened by heat. Your child may feel fatigued and become irritable and intolerant of heat, due to little or no sweating at the affected areas.
