Hot, dry, red skin are symptoms of which thermal emergency?

• A. Heat Exhaustion
• B. Heat Stress
• C. Heat Stroke
• D. Hypothermia

Answer: (C)

Hot, dry, red skin points to heat stroke, a severe and life-threatening failure of the body’s cooling system. When exposure to heat pushes core temperature past about 104°F (40°C), the nervous system can no longer regulate temperature, and sweating often stops, leaving the skin hot or flushed and dry. Mental status changes such as confusion, agitation, or fainting are common as the condition progresses. This differs from heat exhaustion, where the skin is usually sweaty and cooler to the touch, and the person often feels weak or nauseated but not severely delirious. Hypothermia, by contrast, involves cold skin and shivering due to dangerously low body temperature. Immediate medical attention is essential for heat stroke.
