Why does smoke come out of mouth after sneezing?

Answer 1

Usually when you are about to sneeze it is because you either have Allergies to something or other that is around you or because you have a cold or flue and your immune system is reacting to the germs throughout the area that you are in. When you sneeze your immune system is reacting to the germs around you. The snot will come out because your immune system is trying to get the germs out of your body. Therefore water is being released from your respriratory system by sneezing your snot out to get rid of germs.

Answer 2

In general, it doesn't, unless of course you inhaled smoke prior to the sneeze; either that, or perhaps you have a dragon or two in your ancestry.

Thumbs down to that answer. Obviously the question wouldn't be asked if the event wasn't experienced. - What you are witnessing isn't smoke but water vapor. I am willing to bet that you are holding your nose to suppress the sneeze. This causes pressure to build enough that in the correct environment, water vapor can be seen as you exhale.

Answer 3

Snot is an euphemism for mucosal discharge. Mucosal discharge has several duties. First, it lubricates the nostrils and sinus cavities. Second, it's the bodies defense against foreign objects from dirt and pollen to large objects like erasers and such that find their ways into nasal cavities. The mucosal discharge traps the foreign objects and through cilia travels forward out the nostral or down the throat. That is where sneezing and coughing come into play. Lastly, it provides a moisture to air that is breathed in. In arrid climates it keeps the air moist as you breath in. Being that mucosal discharge is mostly water it looses the water to the air.
