Which of the following is listed as a sign of heat exhaustion?

• A. Dizziness
• B. Stroke
• C. Rash
• D. Cramps

Answer: (A)

Dizziness is a classic sign of heat exhaustion. When the body overheats and becomes dehydrated, blood volume can drop and blood flow to the brain decreases, leading to lightheadedness, vertigo, or faintness. This reflects the body’s struggle to cool itself without enough fluids and electrolytes.

Heat exhaustion is milder than heat stroke; you’ll typically see symptoms like sweating, weakness, headache, and nausea along with dizziness. In contrast, heat stroke involves confusion or unconsciousness, a very high body temperature, and hot, dry skin, which is a medical emergency.

Rash isn’t a typical feature of heat exhaustion, and heat cramps, while possible with heat exposure, aren’t the hallmark sign highlighted here. If dizziness occurs in heat, move to a cooler place, rest, and rehydrate. If symptoms worsen or don’t improve, seek medical help promptly.
