Which of these is a normal response in a victim suffering from heat exhaustion?

1. Cyanosis

2. Dry mouth

3. Heavy perspiration

4. Cold skin

The correct answer is: Heavy perspiration

In cases of heat exhaustion, heavy perspiration is a normal physiological response. This condition occurs when the body overheats due to prolonged exposure to high temperatures, often combined with excessive physical exertion. The body's natural cooling mechanism is activated, and as a result, individuals will sweat profusely to help dissipate heat and lower their body temperature. The other potential responses, such as cyanosis, dry mouth, and cold skin, are not typical indicators of heat exhaustion. Cyanosis indicates a lack of oxygen and is more associated with serious medical conditions, while dry mouth is often a sign of dehydration but is not a primary symptom of heat exhaustion. Cold skin can occur in heat-related illnesses, but it is more characteristic of heat stroke or other severe conditions where the body's temperature regulation fails. Therefore, the presence of heavy perspiration is a key sign of heat exhaustion, pointing to the body's attempt to cool itself in response to overheating.
