Hydration is vital for athletic performance as it influences physical capabilities and overall well-being. Proper hydration helps regulate body temperature, lubricates joints, and transports nutrients to cells, all of which are crucial during physical activity. Dehydration, even at mild levels, can lead to fatigue, decreased coordination, and impaired concentration, negatively affecting performance. Additionally, adequate fluid intake aids in recovery by reducing muscle soreness and promoting nutrient absorption. Athletes should monitor their hydration status before, during, and after exercise to maintain optimal performance levels.
