Heat stroke results from the failure of the temperature-regulating capacity of the body.

• A. True
• B. False
• C. Not sure
• D. Sometimes

Answer: (A)

Heat stroke happens when the body's cooling system stops working properly under heat stress. When you’re exposed to hot conditions or engage in intense activity, your body tries to shed heat by sweating and redirecting blood to the skin. If these cooling mechanisms become overwhelmed or fail, the core temperature climbs rapidly, leading to central nervous system dysfunction and potential organ damage. This is why heat stroke is defined by a breakdown in thermoregulation, not by a fever from infection. So the statement is true. Signs you’d see include very high body temperature and confusion or fainting, and the immediate response is to cool the person quickly and seek emergency help.
