• A. True
• B. Often
• C. Sometimes
• D. Never

Answer: (A)

The key idea is that heatstroke is a failure of the body's cooling system. When the body overheats, sweating is a primary way it loses heat through evaporation. If the body can’t regulate temperature effectively, those sweat glands can become overwhelmed or stop producing sweat. That’s why dry, hot skin is a common sign in heatstroke—lack of sweating indicates the body's cooling mechanism has failed. While sweating can occur early in some cases (especially with exertional heat exposure), as heatstroke progresses the sweating often diminishes or stops altogether. So saying that a lack of sweating is a common symptom aligns with how heatstroke presents clinically. Remember, heatstroke is a medical emergency: seek help immediately and start cooling the person while awaiting professional care.
