Scientists finally know why people get more colds and flu in winter

...
In what researchers are calling a scientific breakthrough, scientists behind a new study may have found the biological reason we get more respiratory illnesses in winter. It turns out the cold air itself damages the immune response occurring in the nose.In fact, reducing the temperature inside the nose by as little as 9 degrees Fahrenheit (5 degrees Celsius) kills nearly 50% of the billions of virus and bacteria-fighting cells in the nostrils, according to the study published Tuesday 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, director of otolaryngology at Massachusetts Eye and Ear and an associate professor at Harvard Medical School in Boston.

As it turns out, the pandemic gave us exactly what we need to help fight off chilly air and keep our immunity high, Bleier said.

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

I've always thought wind chill was a factor in catching a cold. Wrong, I guess.

By making you nose cold, it suppresses the virus fighter cells in your nose, thus making it a friendly environment for virus growth.

I have always, since early childhood, been more susceptible to viral infections than the average person.

Multiple causes in my case, but with this information about cold temperatures, I can see that being chilled probably added to the mix.

I can see this breakthrough transforming the u.s. into being a mask wearing culture.

EVERY time. Except I have it on a tether around my neck so I can wear it almost like a necklace and pull it up over my face when I need to. And it IS kinda like a necklace. It's covered in blue rhinestones!

If it's fun to wear, it's probably gonna be worn more often!

Glitz you don’t have to be fearful of showing off in public! And if it’s ever stolen, a replacement costs just a few bucks online.

And besides, sometimes one just needs a little bit of cheap and glitzy fun! I have a blue one. I perk up every time I put it on. So THERE!!!
