1. Painful muscle spasms

2. Extreme thirst

3. Nausea and vomiting

4. Increased heart rate

The correct answer is: Painful muscle spasms

A common symptom of heat cramps is painful muscle spasms. Heat cramps typically occur in muscles that have been overworked and are often associated with strenuous physical activity in hot weather. This condition results from a loss of electrolytes and fluids through sweating, leading to involuntary contractions of the affected muscles. These spasms can be quite painful and may occur in the legs, arms, or abdomen. Recognizing this symptom is crucial for timely intervention, as it signals the body's need for hydration and electrolyte replenishment to prevent more severe heat-related illnesses. Other symptoms can develop, but painful muscle spasms are the hallmark indicator of heat cramps specifically.
