Heat cramps are caused by dehydration and involve which symptoms?

• A. Heat Stroke
• B. Sweating, Weakness, Nausea
• C. Muscle Spasms From Dehydration
• D. Unconscious, Bradycardia

Answer: (C)

Heat cramps occur when dehydration and electrolyte loss disrupt normal muscle function, leading to painful, involuntary contractions after intense sweating in hot conditions. The best description of their symptoms is muscle spasms caused by dehydration. While more severe heat illnesses like heat stroke involve very high body temperature and mental status changes, or heat exhaustion includes sweating, weakness, and nausea, heat cramps are characterized specifically by painful muscle contractions rather than generalized symptoms. Unconsciousness and bradycardia are not typical features of heat cramps. If cramps occur, rest in a cooler place and rehydrate with electrolytes, and seek medical attention if symptoms persist or heat illness signs worsen.
