Hydration significantly impacts exercise performance as it regulates body temperature, maintains electrolyte balance, and supports muscle function. Dehydration can lead to reduced endurance, increased fatigue, and impaired cognitive function, negatively affecting overall performance. Consuming adequate fluids before, during, and after exercise helps prevent these issues, ensuring optimal physical activity. Furthermore, staying hydrated can enhance recovery post-workout and reduce the likelihood of injuries. Therefore, proper hydration is essential for both performance and overall health, underscoring the importance of fluid intake in any fitness regimen.
