Which of the following is a sign of heatstroke?

• A. Cold, clammy skin
• B. Dizziness
• C. Hot flushed skin
• D. Slow breathing

Answer: (C)

Heatstroke happens when the body's cooling system fails and the core temperature climbs rapidly. A major sign is hot, flushed skin because as the body overheats, the skin becomes very warm and red as blood vessels dilate to shed heat. This helps distinguish heatstroke from other conditions where the skin may be cold or sweaty. Dizziness can occur with heat illness, but it isn’t the defining sign of heatstroke. Slow breathing isn’t typical; if anything, breathing may become faster as the body tries to cope. If you suspect heatstroke, it’s a medical emergency—call for help and start cooling the person while waiting for responders.
