Hydration significantly affects exercise performance by regulating body temperature, facilitating nutrient transport, and maintaining overall bodily function. Dehydration can lead to decreased strength, endurance, and cognitive function, ultimately compromising workout efficacy. Proper hydration helps prevent fatigue, cramps, and heat-related illnesses during physical activity. Moreover, drinking adequate water supports recovery post-exercise by aiding cellular repair and rehydration. It's essential for individuals to consume fluids before, during, and after workouts to ensure optimal performance and stay safe while exercising.
