Heat Exhaustion occurs when the circulatory system begins to fail, resulting in rapid, shallow breathing and cool, clammy skin.

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

Answer: (A)

Heat exhaustion happens when overheating leads to profuse sweating and loss of fluids, which reduces circulating blood volume. As the body tries to keep vital organs supplied, the circulatory system is stressed and the heart often works harder, which can manifest as rapid, shallow breathing. The skin stays cool and clammy because sweating is still present, so the body can’t get the heat out as efficiently and the skin remains moist. This combination—circulatory strain, cool, sweaty skin, and relatively quick breathing—is consistent with heat exhaustion, and is distinct from more severe heat illnesses where the skin may be hot or dry and mental status changes appear.
