Hydration plays a critical role in athletic performance. Staying adequately hydrated helps regulate body temperature, lubricates joints, and prevents fatigue. Dehydration can lead to decreased endurance, strength, and coordination, impairing overall performance. Even a small loss of body water can negatively affect cognitive function and reaction times. Maintaining proper fluid balance is essential for athletes to perform optimally, recover faster, and reduce the risk of heat-related illnesses. Therefore, consistent and adequate hydration should be prioritized during training and competition.
