Sports drinks can be beneficial during intense exercise for several reasons. They are formulated to provide electrolytes and carbohydrates, which help replenish what is lost through sweat and maintain hydration. Consuming these beverages can improve endurance and performance, especially during prolonged or strenuous activities lasting over an hour. The sugars in sports drinks offer a quick source of energy, enhancing stamina and reducing fatigue. However, they should be consumed mindfully to avoid excessive sugar intake outside of workouts.
