Here’s Why Science Wants You To Stay Warm


Covering your nose to avoid catching a common cold might work after all, according to a new study.

The study, published in the Proceedings of the National Academy of Sciences, sheds new light into the reproduction of the common cold virus.

According to researchers, the common cold virus is more likely to reproduce when in cooler temperatures inside the nose, rather than the warm core temperature of the rest of the body.

This new finding contradicts what researchers had initially thought in regards to the rhinovirus. Researchers were confident that the rhinovirus would reproduce in slightly cooler temperatures.

Essentially, the immune system becomes impaired when it reaches lower temperatures, Akiko Iwasaki, professor of immunobiology at Yale University, suggested.

“We found that the innate immune response to the rhinovirus is impaired at the lower body temperature compared to the core body temperature,” said Iwasaki.

Furthermore, researchers took the necessary steps to investigate kids with asthma, and how colder temperatures affect their immune system.

After observing viral replication in airway cells from mice with genetic deficiencies in their immune system sensors, they found that with these immune deficiencies, the virus was able to reproduce at the higher temperatures.

“That proves it’s not just virus intrinsic, but it’s the host’s response, that’s the major contributor,” Iwasaki concluded.

So now you know. Get some comfortable clothing, like a scarf, and keep warm or face the common cold viruses.
