Muscle cramps in legs and abdomen are symptoms of which thermal emergency?

• A. Heat Stroke
• B. Heat Exhaustion
• C. Heat Cramps
• D. Heat Stress

Answer: (D)

Muscle cramps during heat exposure point to heat cramps. When you sweat a lot in hot conditions, you lose fluids and electrolytes like sodium and potassium. That imbalance can cause muscles to contract involuntarily, producing painful cramps most often in the legs (calves) and abdomen. Heat cramps are considered a milder heat-related illness and usually occur with heavy sweating and inadequate fluid or electrolyte replacement.

To manage it, stop activity and move to a cooler place, sip a beverage with electrolytes, and gently stretch or massage the cramped muscles. If cramps are severe or persist, or if other concerning symptoms appear (like dizziness, confusion, or fainting), seek medical care. This is distinct from heat exhaustion, which includes symptoms such as dizziness, cool or clammy skin, and faintness, and heat stroke, which involves a dangerously high body temperature and altered mental status.
