What is one sign of heat exhaustion to look out for?

The correct choice highlights pale and clammy skin as a sign of heat exhaustion. When a person is experiencing heat exhaustion, their body struggles to regulate temperature due to excessive heat exposure and loss of fluids. As a result, the skin may appear pale and feel damp or clammy. This occurs because the body is attempting to cool down through sweating, and fluid loss combined with a diminished blood flow to the skin leads to these symptoms.

In contrast, other symptoms associated with heat-related illnesses can manifest differently. For instance, hot, dry skin is more characteristic of heat stroke rather than heat exhaustion, as the body may stop sweating entirely when it reaches dangerous temperatures. A strong, rapid pulse can be a sign of several conditions, but in heat exhaustion, the pulse is often weak and fast due to dehydration. Confusion and disorientation are more severe indicators typically associated with heat stroke, as the brain can start to function abnormally when the body temperature becomes dangerously high.
