What is one symptom of heat stroke or heat stress?

1. Nausea and vomiting

2. Fatigue and exhaustion

3. Rapid heart rate

4. Shivering

The correct answer is: Fatigue and exhaustion

Fatigue and exhaustion are significant symptoms of heat stroke or heat stress. When the body is exposed to excessive heat, it struggles to maintain its normal temperature. This process can lead to an overwhelming sense of fatigue as the body uses energy to cool itself. As the core body temperature rises, individuals may experience a dramatic reduction in physical and mental performance, leading to extreme tiredness or exhaustion. While nausea and vomiting, rapid heart rate, and shivering can indicate other medical issues or stages of heat-related illness, the feeling of extreme fatigue is closely linked to heat stress. In situations of prolonged exposure to high temperatures, combined with physical exertion, fatigue becomes a prominent and alarming symptom, indicating that the body is unable to cope with the heat effectively. Recognizing this symptom is crucial for taking immediate action to cool the individual and prevent further complications associated with heat-related illnesses.
