Having some salty foods and salting your food replaces some of the sodium lost in sweat. Besides having enough sodium in your diet, you can also consume a sports drink that contains adequate sodium. Check the sodium content of your favorite carbohydrate-electrolyte beverage. Pay attention to how many ounces you consume per hour and estimate your sodium intake per hour. You do not need to replace all of your sodium losses. You only need to consume enough sodium to prevent sodium levels from dropping too low. Sports drinks typically contain 20-60 milligrams of sodium per 100 milliliters.
