What are the signs of heat exhaustion?

• A. High fever and rapid heart rate
• B. Dizziness and decreased urine output
• C. Cold skin and shivering
• D. Swelling and rash

Answer: (B)

Heat exhaustion is a serious condition that occurs when the body overheats, often due to prolonged exposure to high temperatures or strenuous physical activity. It is important to recognize its signs and symptoms early to prevent progression to heat stroke, which is more severe.

Dizziness is a common symptom of heat exhaustion because the body struggles to maintain adequate blood flow and oxygenation when overheated. Decreased urine output is another critical sign, as the body attempts to conserve water in response to dehydration, which is common during hot weather or intense exertion. Individuals may also experience heavy sweating, weakness, headaches, and nausea.

The other choices include symptoms that are not typically associated with heat exhaustion. A high fever and rapid heart rate can indicate other medical conditions, while cold skin and shivering are signs of hypothermia, representing the body's response to cold rather than heat. Swelling and rash could suggest an allergic reaction or skin condition rather than heat exhaustion. Understanding these specific symptoms is crucial for timely intervention and ensuring safety in hot environments.
