tl;dr

Cold air can damage the immune response in the nose, which is why people tend to get more colds and flu in the winter, according to a new study published in The Journal of Allergy and Clinical Immunology. "Cold air is associated with increased viral infection because you’ve essentially lost half of your immunity just by that small drop in temperature," said rhinologist Dr. Benjamin Bleier. The study found that reducing the temperature inside the nose by as little as 9 degrees Fahrenheit kills nearly 50% of the billions of virus and bacteria-fighting cells in the nostrils.

At the bottom there is a correction: “Correction: A previous version of this story misstated Dr. Bleier’s title.”

I think they need go and recheck the rest of the article because one of the final paragraphs is:

“Not only do masks prrhinologist Dr. Benjamin Bleierotect you from the direct inhalation of viruses, but it’s also like wearing a sweater on your nose,” he said.

So mouth breathe?

Never. The nasal cavity warms, moistens, and filters the air before it enters the lungs. It also produces nitric oxide, an important gas for the body [1]. The mouth does none of these things.
