Final answer:
A direct cause of heat stroke is when the body temperature becomes too high.
Step-by-step explanation:
A direct cause of heat stroke is when the body temperature becomes too high. Heat stroke occurs when the body's thermoregulatory system is overwhelmed and unable to cool itself down effectively. This can happen when a person is exposed to high temperatures for a prolonged period of time, engages in strenuous physical activity in hot weather, or is in an environment with high humidity.
For example, say someone is running a marathon on a hot summer day without taking appropriate breaks or hydration. They might experience heat stroke because their body temperature climbs to dangerously high levels. In this case, the too high body temperature is the direct cause of heat stroke.
