Hydration is critical for optimal performance during exercise. Drinking water before, during, and after workouts ensures proper fluid balance and helps regulate body temperature. Adequate hydration supports muscle function and minimizes fatigue, which enhances overall performance. It is also vital for recovery, helping to replenish lost fluids and reduce the risk of cramps and injuries. Additionally, staying hydrated can improve cognitive function, allowing for greater focus and intensity during workouts. Thus, proper hydration is key in maximizing the benefits of exercise.
