Likely have you once suffered through a common cold? Probably did you get rid of the cold? Certainly you got over it! You can not treat a runny nose directly, nevertheless your body usually develops resistance to a particular cold virus within a couple of days. We call that being cured by your personal immune system!Adults have previously had a great deal of the cold viruses. Grownups have established immunity to the colds they have suffered from. Therefore there are not lots of runny nose infections existing for adults to catch. That is why adults only get infected with a few runny noses each year whereas children get a dozen colds per year.
