What are the three stages of hyperthermia?

The three stages of hyperthermia are heat cramps, heat exhaustion, and heat stroke. These stages represent a progression of the body's response to extreme heat and its inability to maintain a normal temperature.

Heat cramps are often the first sign, characterized by painful muscle contractions, usually in the legs and abdomen, which can occur during vigorous physical activity in high heat and humidity. They result from a loss of fluids and electrolytes due to sweating.

Heat exhaustion follows, which is more severe and can cause symptoms like heavy sweating, weakness, dizziness, nausea, and fainting. It indicates that the body is overheating and unable to cool down effectively, necessitating immediate intervention to prevent further complications.

Heat stroke is the most critical and life-threatening stage. It occurs when the body temperature rises above 104°F (40°C), leading to symptoms such as confusion, altered mental state, loss of consciousness, and potentially organ failure. At this stage, the body's heat regulation mechanisms have failed entirely, requiring urgent medical attention.

Recognizing these stages is vital for effective treatment and prevention of serious health risks associated with extreme heat exposure. The other options mentioned do not accurately depict the stages of hyperthermia. For instance, frostbite and hypothermia are conditions related to extreme
