Are symptoms of heat exhaustion characterized by dizziness, rapid weak heartbeat, heavy sweating, and headaches?

The symptoms of heat exhaustion indeed include dizziness, a rapid weak heartbeat, heavy sweating, and headaches. Heat exhaustion occurs when the body overheats due to prolonged exposure to high temperatures, particularly during physical exertion in hot weather.

Dizziness can arise from a combination of dehydration and reduced blood flow to the brain, while a rapid weak heartbeat is a response to the body's attempt to cool down and maintain adequate blood circulation. Heavy sweating is the body's natural mechanism to dissipate heat, and headaches can occur due to dehydration and electrolyte imbalances.

Recognizing these symptoms is vital for early intervention, as untreated heat exhaustion can progress to heat stroke, which is a more severe and life-threatening condition. Therefore, the correct answer affirms the recognition of these symptoms as indicators of heat exhaustion.
