Which of the following is NOT a sign of heat stroke?

Heat stroke is a severe condition that occurs when the body's temperature regulation system fails, typically due to prolonged exposure to high temperatures. It can lead to serious complications and is characterized by specific signs and symptoms.

One of the hallmark signs of heat stroke is red, hot, dry skin, which indicates that the body is unable to cool itself through sweating. Altered levels of consciousness, such as confusion or disorientation, are also crucial indicators because the extreme heat affects the brain and overall mental function. Rapid, shallow breathing can occur as the body attempts to accommodate the heat and maintain oxygen levels.

In contrast, increased appetite is not associated with heat stroke. During this severe condition, the body is focused on surviving and regulating temperature rather than engaging in normal physiological processes like digestion. In fact, individuals experiencing heat stroke may have nausea or loss of appetite as a result of the body's stress response.

Thus, the choice that identifies increased appetite as not being a sign of heat stroke is accurate, as it does not align with the physiological responses one would expect in such a critical situation.
