Why is hydration important during physical activity?

Hydration is crucial during physical activity because it helps maintain performance and reduces the risk of dehydration-related complications. When the body is well-hydrated, it can regulate temperature more effectively, transport nutrients efficiently, and maintain blood volume, all of which are essential for optimal physical performance. Dehydration can lead to fatigue, loss of coordination, decreased endurance, and decreased muscle strength, which can impair an individual's ability to perform at their best during exercise or sports.

Furthermore, appropriate hydration levels help prevent complications such as heat exhaustion or heat stroke, which can occur in high-intensity or prolonged activities, especially in warm environments. By keeping the body adequately hydrated, an individual is better equipped to endure physical challenges and recover effectively after exercise.
