What is a common symptom of heat stroke that requires immediate attention?

High body temperature is a defining symptom of heat stroke and signifies a severe medical emergency. Heat stroke occurs when the body overheats, typically due to prolonged exposure to high temperatures, often combined with dehydration. The body's temperature regulation system fails, leading to temperatures that can exceed 104°F (40°C).

This elevated body temperature can cause damage to the brain and other vital organs and can lead to serious complications or even death if not treated quickly. Therefore, recognizing high body temperature as a critical symptom is essential, as it indicates the need for immediate medical intervention, including cooling the body and restoring fluid balance, to prevent further health issues.

While dehydration, weak pulse, and lightheadedness can be associated with heat-related illnesses, they are not as definitive in diagnosing heat stroke as the presence of a dangerously high body temperature. These symptoms may also manifest in other conditions, making them less specific in indicating a heat stroke scenario.
