What are the symptoms of heat exhaustion?

Correct Answer: Option B — Pale, clammy skin with profuse sweating

Heat exhaustion results from excessive fluid loss and electrolyte imbalance. Symptoms include pale, clammy skin, profuse sweating, rapid pulse, and dizziness. Unlike heat stroke, where the body's cooling mechanism fails, heat exhaustion involves active sweating as the body attempts to regulate temperature. Immediate cooling and rehydration are critical maritime safety protocols.
