The temperature in your nose is why you get more colds and flu in winters: Study | The Times of India

“EV’s can’t divide like cells can, but they are like little mini versions of cells specifically designed to go and kill these viruses,” said rhinologist Dr. Benjamin Bleier, director of otolaryngology at Massachusetts Eye and Ear and an associate professor at Harvard Medical School in Boston.

“EV’s act as decoys, so now when you inhale a virus, the virus sticks to these decoys instead of sticking to the cells,” Dr. Bleier added.

The researchers found that when under attack, the nose increases production of extracellular vesicles by 160%.
