By chance have you a while ago been down with a runny nose? Peradventure did you do away with the cold? Certainly you got over it! You can't treat an acute rhinitis directly, however your immune system generally creates resistance to any type of cold infection within a few weeks. We call that being healed by your personal immune system!Grownups have previously had a great deal of the rhinitis viruses. Adults have created immunity to the viruses they have had. Therefore there are not numerous cold infections remaining for adults to become infected with. That is why adults just succumb to a couple of runny noses each year whereas kids succumb to a dozen runny noses annually.
