Muscle cramps are involuntary contractions that occur in various muscles. They may occur during exercise, at rest, or at night, depending upon the exact cause. However, muscle cramps are often associated with dehydration. Correct answer:D
Through dehydration (example:exercise hard in hot conditions and do not drink sufficient liquid.) the body loses minerals like potassium, calcium, magnesium and/or sodium which results in muscle cramps.
