Which of the following is NOT a category of heat injury?

• A. Heat cramps
• B. Hypothermia
• C. Heat exhaustion
• D. Heatstroke

Answer: (B)

Heat-related problems arise from being in hot conditions, and the main categories to recognize are heat cramps, heat exhaustion, and heatstroke. Hypothermia, by contrast, comes from exposure to cold and a drop in body temperature, so it is not a heat injury. That’s why hypothermia is the option that does not fit as a category of heat injury. Understanding the distinction helps you assess and respond appropriately: heat cramps are painful muscle spasms from dehydration and electrolyte loss, heat exhaustion involves weakness, sweating, and dizziness with overheating, and heatstroke is a medical emergency with a very high body temperature and altered mental status requiring rapid cooling and urgent care.
