We ve all been there, running for a bus or train on a cold morning only to find that our nose is also running! Grab some tissues and learn the science behind the phenomenon known as "skier s nose."
A nose that runs like a tap in winter is business as usual for many people, especially those with chronic allergic or nonallergic rhinitis(鼻炎). It’s even got an official diagnosis: skier’s nose. Apparently, getting a runny nose when we step out into a cold winter is a bodily defense mechanism, according to Murray Grossan, MD, of the Grossan Sinus and Health Institute. That’s because the nose has two main purposes: 1) to filter bacteria so they don’t reach our lungs; 2) to warm the air before it reaches our lungs.
All you experience is the nose working overtime to produce more fluids to help move bacteria along. Dr. Grossan says to help it out, try physically to warm your nose when you come inside: “Rub your hands together, and then breathe into cupped hands or inhale steam from hot green tea and drink it, as green tea stimulates cilia(纤毛).”
Our nose runs in winter for one more purpose, which is to fight against the drier outside /inside air. “It needs to humidify the air we breathe in, which is done by the mucus and various secretions in our nasal cavity(鼻腔),” says Ehsan Ali, MD, of Beverly Hills Concierge Doctor in California. “In winter, or when it’s cold outside, the air is much drier than in the summer, which is more humid. Our noses respond by producing more secretions and mucus to help humidify the air to a level our bodies need.” When there’s a lot of fluid being produced, that’s when it starts to run out of the end of your nose.

根据Grossan Sinus and Health Institute的医学博士默里·格桑的说法,显然,当我们在寒冷的冬天出门时流鼻涕是身体的一种防御机制。
