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

More from CNN: “A chill is in the air, and you all know what that means — it’s time for cold and flu season, when it seems everyone you know is suddenly sneezing, sniffling or worse. It’s almost as if those pesky cold and flu germs whirl in with the first blast of winter weather. Yet germs are present year-round — just think back to your last summer cold. So why do people get more colds, flu and now Covid-19 when it’s chilly outside? 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.

More from NPR: “Evan Gora has never been struck by lightning, but he’s definitely been too close for comfort. ”When it’s very, very close, it just goes silent first,” says Gora, a forest ecologist who studies lightning in tropical forests. “That’s the concussive blast hitting you.
