What causes some people to be particularly prone to heatstroke in summer?

Heatstroke is particularly common in summer, mainly due to high temperatures, humid weather, and pre-existing medical conditions.

1. High Temperature

During summer, the air temperature is often very high. The body sweats excessively, leading to fluid loss and metabolic disturbances, which can result in heatstroke.

2. Humid Weather

Heatstroke is also more likely in hot and humid environments. In summer, when temperatures are high, the body normally cools itself through sweating. However, high humidity impedes sweat evaporation, disrupting the body's thermoregulatory center and potentially causing heatstroke.

3. Pre-existing Medical Conditions

If a person already has certain health conditions such as hypertension or anemia, they are more susceptible to insufficient blood supply to the brain in high-temperature environments, increasing the risk of heatstroke.

In addition, elderly individuals and those with weak physical conditions are also more prone to heatstroke. It is recommended to promptly move to a cool, well-ventilated environment, drink an appropriate amount of light salt water, and get adequate rest to help alleviate symptoms.
