Final answer:
Profuse sweating is not a symptom of heat stroke; it is characterized by hot, dry skin due to the failure of the body's cooling mechanism.
Step-by-step explanation:
All of the following conditions are symptoms of heat stroke, EXCEPT for profuse sweating. Heat stroke occurs when your body overheats, usually as a result of prolonged exposure to or physical exertion in high temperatures. One of the hallmark signs of heat stroke is hot, dry skin, as the body's sweating mechanism typically fails. In this state, the body is unable to cool down, leading to symptoms such as hot, dry skin, a rapid heartbeat, confusion, and even loss of consciousness. When experiencing heat stroke, the lack of sweating indicates that the body can no longer compensate for the high temperature and is a serious medical emergency requiring immediate attention.
