What is a common sign of heat stroke?

A common sign of heat stroke is confusion and seizures, which indicates a serious disruption in the body's ability to regulate its temperature and can lead to significant neurological impairment. Heat stroke occurs when the body overheats, typically due to prolonged exposure to high temperatures or strenuous exercise in hot conditions. As the body's temperature rises above 104°F (40°C), central nervous system dysfunction can manifest as confusion, agitation, irritability, and, in severe cases, seizures or loss of consciousness.

In contrast, excessive sweating is more characteristic of heat exhaustion rather than heat stroke, where the body is still attempting to cool itself. Blue lips are a sign that may indicate severe hypoxia or a lack of oxygen, which is not typically associated with heat stroke. Low body temperature is contradictory to the nature of heat stroke, as this condition is defined by an elevated body temperature, not a low one. Recognizing confusion and seizures as symptoms of heat stroke is crucial for immediate intervention and treatment.
