Why does the cold weather make my nose run?

“It’s part of your nose’s job to condition the air as it travels to your lungs.

“Part of this conditioning process is to moisturize the air.  Often, in cold weather, the air is dry as well.  As a result, the nose reflexively begins to increase fluid production for this conditioning process.

“When fluid production increases, the nose begins to run.

“Secondly, during exhalation in cold weather, the moisture in the air being exhaled into a colder environment condenses from gas to liquid, usually collecting at the tip of one’s nose — creating an increase in nasal discharge.”
