2 . For many of us, winter colds come regularly. Whatever we do, winter colds and the flu (流感) always find a way to get in, making us cough and sniffle (抽鼻子) into our scarves.
In fact, when a virus (病毒) like the winter cold enters the body through the nose, the cells (细胞) in the nose start producing simple copies of themselves called extracellular vesicles, or EVs (胞外囊泡)
Recently, a team of scientists think they may have found out why we get more viruses in winter. It's because cold temperatures actually make our noses worse at fighting viruses.
The scientists did tests on cells taken from the noses of human volunteers, because they wanted to find out more about how EVs fight viruses and how well they work in colder temperatures. The results showed that EVs are usually very good at catching viruses, but they don't work so well at lower temperatures. They found that in colder temperatures, the number of EVs produced decreases (减少) by more than 40%, meaning the nose might not be good at stopping viruses from getting further into the body.
Benjamin Bleier, one of the study's scientists, said the results gave the first perfectly reasonable explanation for why we get more colds in the winter months.
And, he said that wearing a mask in winter may not only stop some viruses from getting in, it may also help produce more of those EVs while keeping the nose a little warmer.
