Cooler Noses May Be Key to Winter's Spike in Colds
TUESDAY, Dec. 6, 2022 (HealthDay News) -- Researchers may have sniffed out why colds are more likely in wintertime: The answer may lie within the nose.
A previously unidentified immune response inside the nose is responsible for fighting off the viruses that cause upper respiratory infections, according to researchers at Massachusetts Eye and Ear and Northeastern University in Boston.
Unfortunately, cold weather inhibits this protective response, making it more likely that a person will come down with anything from a cold to COVID-19.
The new study offers the first biological explanation why respiratory virus infections are more likely to spike in colder seasons, researchers said.Full Article
