Dehydration affects muscle function by impairing electrolyte balance, which is crucial for muscle contractions. Insufficient fluids can lead to decreased strength, endurance, and coordination, making physical activities more challenging. Even mild dehydration can result in increased fatigue and reduced performance during workouts. In severe cases, it may cause cramping or even heat-related illnesses. Maintaining hydration before, during, and after exercise is crucial for optimal muscle function and overall performance. Aiming to drink enough fluids, particularly during intense workouts or in hot conditions, is key to supporting muscle health and performance.
