What is a typical symptom of heat stroke?

Changes in mental status is a typical symptom of heat stroke due to the body overheating and the brain being affected. When exposed to extremely high temperatures, the body's ability to regulate its temperature can fail, leading to a rapid rise in core body temperature. This can disrupt normal brain function, resulting in confusion, altered behavior, dizziness, and even loss of consciousness.

In contrast, excessive sweating is more commonly associated with heat exhaustion rather than heat stroke since heat stroke typically involves a cessation of sweating due to severe dehydration. Skin rash and nausea and vomiting can also occur in various heat-related illnesses but are not definitive indicators of heat stroke. Understanding these symptoms is crucial for proper diagnosis and treatment in emergency situations.
