Which of the following symptoms is indicative of heat exhaustion?

The symptoms associated with heat exhaustion include flu-like aching and cold clammy skin. This condition occurs when the body loses an excessive amount of water and salt, often due to prolonged exposure to high temperatures and physical exertion. The body's response can manifest in symptoms such as malaise, general discomfort, and the skin appearing cool and moist. This combination provides clear indicators that the body is struggling to cope with heat stress.

Extreme thirst is a common symptom of dehydration, which may occur in various heat-related illnesses but isn’t specific to heat exhaustion. While an elevated temperature above 106 degrees is more indicative of heat stroke, another severe condition, it is not characteristic of heat exhaustion, which typically involves a less extreme rise in body temperature. Severe headache and confusion may indicate more advanced heat-related illnesses, such as heat exhaustion or heat stroke, but the cold clammy skin is a defining feature of heat exhaustion, distinguishing it from the more severe conditions that present differently.
