Hydration significantly influences athletic performance, as even mild dehydration can impair endurance, strength, and cognitive function. Proper fluid intake ensures that the body can regulate temperature, transport nutrients, and maintain optimal muscle function. Hydration also aids in recovery, helping to prevent cramps and fatigue during prolonged exertion. Athletes should be conscious of their hydration needs before, during, and after exercise, as water is crucial for peak performance and overall physical health.
