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

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

Answer: (A)

When the body works hard in heat, you lose water and electrolytes through sweating. If fluids and salt aren’t replaced, the resulting electrolyte imbalance can disrupt how nerves and muscles function, causing painful muscle contractions. That pattern—muscle pains or spasms that appear during strenuous activity because of sweating and insufficient fluid or salt intake—is the hallmark of heat cramps. Other heat-related problems have different clues: heat exhaustion typically brings fatigue, dizziness, and weakness with dehydration; heat stroke is a dangerous emergency marked by very high body temperature and altered mental status; sunburn is skin damage from UV exposure, not a neuromuscular issue caused by electrolyte loss. To prevent cramps, stay hydrated with electrolytes and salt as appropriate, and acclimate to heat gradually. If cramps occur, rest, gently stretch the affected muscles, and rehydrate; seek medical care if cramps are severe or if other warning signs of heat illness appear.
