Hydration plays a crucial role in preventing muscle cramps during exercise by maintaining fluid balance and facilitating proper muscle function. Dehydration can lead to an imbalance of electrolytes, essential minerals necessary for muscle contractions and relaxation. Adequate fluid intake helps regulate body temperature and supports overall physical performance. Consuming water before, during, and after exercise is vital, especially in hot conditions or during prolonged activity. Prioritizing hydration promotes endurance and helps reduce the likelihood of cramps and other heat-related issues.
