Which heat-related disorder involves muscle pains or spasms during strenuous activity due to electrolyte imbalance from sweating without adequate fluid or salt intake?

• A. Heat Exhaustion
• B. Sunburn
• C. Heat Cramps
• D. Heat Rash

Answer: (C)

When you’re doing strenuous work in hot conditions, your muscles rely on electrolytes like sodium and potassium to function properly. If you sweat a lot and don’t replace fluids and salt, those electrolyte levels drop, which disrupts nerve and muscle signaling and leads to painful muscle cramps, often in the calves, thighs, or abdomen during or after intense activity. This differs from heat exhaustion, which involves dizziness, weakness, nausea, headache, and dehydration with the body’s cooling system overwhelmed. Sunburn is skin damage from UV exposure, and heat rash is a skin irritation from blocked sweat glands. To help prevent and treat cramps, stop activity, rehydrate with fluids containing electrolytes, and gently stretch the affected muscle.
