Heat-related illnesses happen when a person heats up faster than they can cool down. Symptoms range from mild to severe and can quickly escalate into a medical emergency if untreated—but you can prevent heat-related illness in most cases.

Early signs include nausea, light-headedness, fatigue, muscle cramping, and dizziness. Heat-related illness can affect everyone – even those accustomed to working in the heat. If heat exhaustion progresses to heat stroke, it is a medical emergency that, untreated, can lead to death.
