2. Lack of sweat

3. Headache and dizziness

4. Rapid breathing

The correct answer is: Lack of sweat

A key symptom of heatstroke is the lack of sweat. This condition arises when the body becomes unable to regulate its temperature, often due to prolonged exposure to high temperatures or strenuous physical activity in hot weather. Unlike heat exhaustion, where excessive sweating occurs as the body attempts to cool itself, heatstroke signifies a failure of the body's thermoregulatory processes, leading to a significant reduction in sweating or complete absence of it. This indicates an advanced state of overheating, where the body's core temperature can rise to dangerous levels, leading to severe health consequences. Recognizing the lack of sweat is crucial for identifying heatstroke, as it sets this life-threatening condition apart from other heat-related illnesses. In cases of heatstroke, other symptoms may include confusion, altered mental state, and potentially unconsciousness, signaling the urgent need for immediate medical attention. Knowing about the absence of sweating as a symptom helps individuals and responders take appropriate action to cool the affected person and seek help.
