Hyperthermia is best described as:

Hyperthermia is best described as:

• A. Overheated body with thermoregulation failure
• B. Low body temperature
• C. Dehydration due to heat
• D. Muscle cramps during exercise

Answer: (A)

Hyperthermia happens when the body overheats because its cooling mechanisms can’t keep up with the heat load. It’s an overheated body with thermoregulation failure, not a fever. Normally the body cools itself through sweating and widening blood vessels in the skin; when those processes are overwhelmed or impaired, the core temperature rises. This distinction matters in practice: hyperthermia can occur from intense exercise in hot conditions or prolonged exposure to heat, especially if hydration is poor. Signs to watch for include feeling faint, confusion, dizziness, flushed skin, and rapid pulse, and in severe cases it can progress to heat stroke. The remedy is to move to a cooler environment, remove excess clothing, and begin cooling (cool water, fans, ice packs) and hydration. The other descriptions don’t capture the whole picture: a low body temperature describes hypothermia, not hyperthermia; dehydration due to heat is a contributing factor but not the definition; muscle cramps during exercise are a different heat-related issue and not the overall description of hyperthermia.
