What characterizes heat stroke symptoms?

Heat stroke is a serious condition that occurs when the body becomes unable to regulate its temperature, leading to a rapid increase in core body temperature. The key characteristics of heat stroke include hot, dry skin and a high body temperature. In this condition, the body's natural cooling mechanisms, such as sweating, become ineffective due to extreme heat exposure. As a result, the skin feels hot and is often dry, since the body is unable to sweat. This is a critical, life-threatening emergency that requires immediate medical attention.

The presence of high body temperature, usually exceeding 104°F (40°C), coupled with the absence of perspiration, distinguishes heat stroke from other heat-related illnesses. These symptoms can lead to a range of severe complications, including neurological impairment and organ failure if not promptly treated. Understanding these vital signs is essential for recognizing and responding to heat stroke effectively.
