What is NOT a symptom of heat exhaustion?

In the context of heat exhaustion, the most relevant symptom that is not associated with this condition is dry skin. When someone is experiencing heat exhaustion, the body typically reacts to overheating by sweating extensively in an effort to cool down, which generally leads to pale and clammy skin due to moisture. Accompanying symptoms often include weakness and nausea, both of which are common indicators that the body is struggling with heat stress. Dry skin, however, signifies a lack of sweating and is more indicative of heat stroke or conditions where the body is unable to cool itself, rather than heat exhaustion itself. Thus, identifying dry skin as a symptom indicates a misunderstanding of how the body responds to heat exhaustion, making it the correct answer in this context.
