Many of us have heard: “Don’t go outside without a coat; you’ll catch a cold.”

That’s not exactly true. As with many things, the reality is more complicated. Here’s the distinction: Being cold isn’t why you get a cold. But it is true that cold weather makes it easier to get the cold or flu. It is still too early to tell how weather impacts the COVID-19 virus, but scientists are starting to think it behaves differently than cold and flu viruses.

And one more important thing this year: When it’s your turn, make sure you get the COVID-19 vaccine.
