Heat cramps are defined as what?

Heat cramps are defined as what?

• A. Painful muscle cramps caused by fatigue alone.
• B. A condition where the body loses too much water, causing overheating.
• C. A sudden collapse due to heat exposure and loss of consciousness.
• D. Painful spasms in the muscles due to fatigue or sodium lost via sweat.

Answer: (D)

Heat cramps are painful muscle spasms that occur after intense activity in hot conditions. The crucial idea is that they arise from a combination of muscle fatigue and loss of electrolytes, especially sodium, through sweat, which disrupts normal muscle function. That’s why a description that defines heat cramps as painful spasms in the muscles due to fatigue or sodium lost via sweat is the best fit. Other descriptions describe overheating from dehydration without cramps, a collapse from heat exposure, or cramps caused by fatigue alone without mentioning electrolyte loss.
