As we breathe, germs and particles get into our nose and nasal passages. The purpose of snot is to trap these germs and particles to prevent them from entering our lungs. Blowing your nose allows you to get rid of these negative things to both help avoid getting sick as well as getting rid of a cold or illness.

Mucus is also essential in smelling. As we breath through our noses, scent particles travel into the nose and then are dissolved in the mucus so that the nerve receptors in the sinus passage can transmit the signals to the brain.
