Which population is most vulnerable to the effects of heat waves?

1. Teenagers

2. Athletes

3. Elderly people

4. Swimmers

The correct answer is: Elderly people

Elderly people are the most vulnerable population to the effects of heat waves. Studies have shown that older adults are particularly susceptible to heat-related illness because their bodies may not adjust well to sudden temperature changes or extreme heat. Teenagers and athletes may be more physically active, but they generally have healthier, stronger bodies that are more able to regulate temperature. Swimmers may have an increased risk due to exposure to heat during competitions or training, but this does not make them more vulnerable than elderly individuals who may have existing health conditions. The elderly have a higher rate of chronic conditions and may have more difficulty adapting to the physiological changes that occur during a heat wave. Therefore, elderly people are the most at risk and require special attention during heat wave events.
