The relationship between hydration and exercise efficiency is critical, as adequate fluid intake supports optimal physical performance. When dehydrated, even mild fluid loss can impair endurance, decrease strength, and elevate perceived exertion during workouts. Hydration aids in regulating body temperature and joint lubrication, facilitating smoother movement. It's recommended to consume fluids before, during, and after exercise to maintain hydration levels. Adequate hydration also contributes to quicker recovery post-exercise by replenishing lost fluids and supporting metabolic function. Thus, staying hydrated is essential for achieving peak exercise performance.
