Sneezes and runny noses are usually caused by irritation of the mucous tissues. The sneeze is intended to blow out any particles and the runny nose is to wash them out. Even if there are no particles and there is just irritation from a cold or flu virus, your body still has the reflective responses trying to keep the airways clear.
To help wash out your nose, making sure that whatever made you sneeze is totally gone.

When you sneeze, air is forcefully blasted out of your mouth and nose, helping to get rid of what was that made you sneeze.
