Definition
By Mayo Clinic staffHeatstroke is a life-threatening condition that occurs when your body temperature reaches 104 F (40 C) or higher. Heatstroke can be brought on by high environmental temperatures, by strenuous physical activity, or by other conditions that raise your body temperature. Whatever the cause, you'll need immediate medical attention to prevent brain damage, organ failure or death.
Heatstroke is the escalation of two other heat-related health problems: heat cramps and heat exhaustion. In these conditions, you develop signs and symptoms that are milder than those of heatstroke. You can prevent heatstroke if you receive medical attention or take self-care steps as soon as you notice problems.
