Have you ever wondered if sports drinks really hydrate your body better than water? In short, the answer is no. There's still no substitute for clear, fresh water when it comes to replacing the water in your body that's lost when you exercise. And with zero calories, it's the thirst quencher of choice for people who are trying to manage their weight.
However, that doesn't mean sports drinks don't have their place. Sports drinks contain minerals called electrolytes (including salt and potassium) that your body loses when you sweat. Electrolytes are necessary for carrying out many functions in the body, so replacing lost electrolytes with a sports drink can be beneficial when you're exercising for more than 60 minutes at a time or when you are sweating excessively, as in hot weather.
Sports drinks also contain carbohydrates (in the form of sugar) for energy, which can also be beneficial if you're working out for more than an hour. But be aware that with energy comes added calories. While sports drinks are lower in calories than fruit juice or soft drinks, they still contain about 50 calories per 8-ounce serving, which can add up quickly if you drink, say, an entire 32-ounce bottle over the course of your workout.
The bottom line? Go ahead and have a sports drink to help yourself rehydrate and refuel during long, strenuous workouts. But for shorter or less intense workouts, make water your sports beverage of choice.
