So in times of heavy exercise, is it better then to effectively drink saline? Assuming one doesn't mind the salty taste.
Well, during heavy excercise, a lot more than salt is lost. Another thing lost is blood glucose. It can help you recover to replece the glucose as well, so the sugar in sports drinks can be useful as well.
You could buy ORS (oral rehydration salt) from a pharmacy and mix it in water. Make sure the packet follows the WHO formula, and that you add the correct amount of water. If these are not available, the WHO recommends 3 g salt and 18 g sugar per litre (roughly 1 teaspoon and 6 teaspoons per litre) of water. But this will not have potassium and other minerals.
