Perhaps have you formerly had a runny nose? Peradventure did you recover from the problem? Obviously you recovered! You won't treat a runny nose directly, however your immune system usually creates resistance to any cold infection within a few days. We call that being healed by your very own immune response!

Grownups have currently had a great deal of the rhinitis infections. Parents have created resistance to the ones they have actually suffered from. So there are not quite as many runny nose infections remaining for grownups to acquire. That is why parents just get a few colds annually whereas kids may get a dozen runny noses each year.
