Symptoms of heat exhaustion include ____.

Heat exhaustion occurs when the body is unable to adequately cool itself in high-temperature conditions, leading to a depletion of fluids and electrolytes. The symptoms are a result of this imbalance and the body's stress response to overheating.

Muscle weakness can occur as the body becomes fatigued and dehydrated, impacting muscular function. A headache is also a common symptom, often resulting from dehydration, reduced blood flow, or changes in body temperature regulation. Shortness of breath may occur as the body struggles to maintain adequate oxygen levels and manage heat stress.

Given that heat exhaustion can manifest with a range of symptoms, including all the listed options, it is accurate to conclude that all of these symptoms can be indicative of this condition. Recognizing the various signs is essential for early intervention and treatment to avoid more severe heat-related illnesses.
