why does my nose run when i eat soup

The inside of your nose contains mucous membranes. These little guys kinda excrete a bit of stuff when needed to keep your nasal passages nice and wet, but not too much. Just enough to keep it from drying up and becoming very irritating. The inside of your nasal passages isn t as durable and tough as your regular skin. Now, when you eat hot soup, your soup is constantly releasing vapor, that steam that comes off the top of a nice warm bowl freshly off the stove.


That vapor actually increases the humidity inside your nose because usually you re sitting right above it. The vapor naturally goes right up in there. When you sweat when it s very humid, you might notice you get really wet. It s the same thing, but inside your nose. The water can t evaporate properly, since there s so much water in the air already, so it condenses into it s liquid form. Outside of your nose is much drier, so it doesn t get wet, obviously.


But since the inside of your nose is already wet, the water has nowhere to go but running out of your nose. Hope this helped!
Q: Why does eating hot soup or spicy food cause a runny nose? Dr. Dave says: It s called, which is actually very common, and for a lot of people very annoying. Just as an FYI, the vasomotor refers to what in this case is a bit of an overreaction of the lining of your nostrils to some kind of irritation.


And any time you see itis on the end of a word, it refers to inflammation. So basically, when the lining of your nose is exposed to something that irritates it-and some people s nostrils are more sensitive than others-you get an inflammatory response that starts with the tiny blood vessels inside your nose dilating and the cells in your nostrils secreting mucus. What you often wind up with is rhinorrhea, i. e. watery or mucousy drainage, congestion, sneezing, and itching.


What s interesting is that lots of things can cause this, including (such as perfume, scented candles), alcoholic beverages, irritants (secondhand smoke, diesel exhaust), environmental factors (exposure to air conditioning or changes in air temperature), stress (emotional or physical), hormone changes (during menstruation, for example) and certain medications, many of which are in common use, among others.
