Heat stress occurs when the body cannot cool itself enough to maintain a healthy temperature. Heat-related illnesses include heat rash, heat cramps, dizziness or fainting, heat exhaustion, heat stroke, and a worsening of existing medical conditions. Overexertion in hot weather, sun or bushfire exposure, and exercising or working in hot, poorly ventilated or confined areas can increase your risk of heat stress.
