Heat cramps are most commonly characterized by which symptom?

• A. Muscle cramps in calves or abdomen
• B. Profuse sweating with dizziness
• C. High fever and vomiting
• D. Numbness of fingers

Answer: (A)

Heat cramps occur when intense activity in hot conditions leads to fluid and electrolyte losses, causing involuntary muscle contractions. The hallmark symptom is cramping of muscles, most often in the calves or abdomen. This fits heat cramps best because it directly reflects the muscle involvement from electrolyte imbalance and dehydration. The other descriptions point to different heat-related problems: profuse sweating with dizziness suggests heat exhaustion, a high fever with vomiting indicates heat stroke, and numbness of the fingers isn’t typical for heat-related illness. To manage heat cramps, rest in a cooler place, gently stretch and massage the cramped muscles, and rehydrate with fluids that contain electrolytes. If cramps persist or there are signs of heat illness, seek medical care.
