 Wow. Does that make sense? Totally. And so that's why you want to make sure that you're hydrated, that you're using a nasal spray with xylitol. And some people use saline sprays. Saline sprays are good, but xylitol is much better. And the reason for that is because when you use a saline spray, after about half an hour, your nose is going to be dried out. And the reason for that is that you have an active transport system in your tissue right there that moves the salt from your mucus into the tissue.
