Which of the following is a characteristic of heatstroke?

• A. Cold, pale skin
• B. Numbness in fingers
• C. Rapid heartbeat
• D. Hot flushed skin

Answer: (D)

Heatstroke is a medical emergency where the body can no longer cool itself effectively. A defining sign is hot, flushed skin because the body's temperature regulation has been overwhelmed and surface vessels are very warm. Sweat may be present early, but as heatstroke progresses the skin often feels dry and extremely warm to the touch. This makes hot, flushed skin the clearest clue among the options. Cold, pale skin points to cold-related conditions or shock, numbness in fingers isn’t a typical heat illness sign, and a fast pulse can occur with many problems and isn’t as specific to heatstroke as the skin’s appearance. If heatstroke is suspected, call for help right away and begin cooling the person while awaiting medical assistance.
