What causes your body to overheat and hyperthomia and how do you treat them?

Overheating and hyperthermia can occur when the body's heat production exceeds its ability to dissipate heat, often due to factors like excessive physical exertion, high environmental temperatures, or dehydration. Symptoms may include elevated body temperature, confusion, rapid heartbeat, and nausea. Treatment involves moving to a cooler environment, rehydrating with fluids, and using cooling methods like cool baths or ice packs. In severe cases, medical attention may be necessary to prevent complications.
