Which signs constitute major signs of heat exposure?

• A. Heat exhaustion and heat stroke
• B. Sunburn
• C. Nausea
• D. Sneezing

Answer: (A)

Heat exposure is most seriously reflected by the two conditions that show the body's cooling mechanisms failing: heat exhaustion and heat stroke. Heat exhaustion signs include heavy sweating, weakness, dizziness, nausea, clammy skin, and a fast or weak pulse. If it progresses, it can become heat stroke, a true medical emergency characterized by a very high body temperature (usually above 103°F/39.4°C), altered mental status such as confusion or agitation, hot or dry skin, rapid pulse, and sometimes seizures or loss of consciousness. Recognizing these signs early is crucial because heat stroke requires immediate cooling and urgent medical attention. Sunburn is skin damage from ultraviolet exposure, not a direct sign that the body is overheating. Nausea can occur for many reasons and isn’t specific enough to indicate major heat exposure on its own. Sneezing is not related to heat exposure. If you suspect heat stroke, seek emergency help right away, move the person to shade or a cool area, remove excess clothing, and start cooling the body with lukewarm water or fans while awaiting help.
