Maybe have you formerly suffered through a common cold? Maybe did you do away with the cold? Obviously you recovered! You can not cure an acute rhinitis itself, but your body usually develops resistance to a certain cold infection within several weeks. That is called being cured by your own immunity!

Adults have already had a great deal of the cold viruses. Grownups have created resistance to the ones they have actually had. So there are not quite as many cold viruses remaining for grownups to become infected with. That is why grownups just get infected with a few colds per year whereas children may get 10-12 runny noses each year.
