What type of heat injury is characterized by severe body overheating?

Heat stroke is characterized by severe body overheating, typically resulting from prolonged exposure to high temperatures, especially in combination with strenuous physical activity. This condition occurs when the body's temperature regulation fails, leading to a rapid increase in core body temperature, often exceeding 104 degrees Fahrenheit (40 degrees Celsius).

Heat stroke is a medical emergency that can lead to organ failure and death if not treated promptly. The body loses its ability to cool itself through sweating, and symptoms may include confusion, altered mental state, unconsciousness, and a lack of sweating despite the heat. Recognizing the severity of heat stroke is crucial, particularly for individuals engaged in strenuous activities or those exposed to hot environments for extended periods.

While heat exhaustion, heat cramps, and heat rash are also conditions associated with heat exposure, they do not involve the same level of critical overheating and associated health risks as heat stroke does.
