How does cold weather affect the flu virus?

It's been bitterly cold this week. And it's not going to get much warmer this weekend.

When it comes to the flu, these cold temperatures can affect how the virus is spread.

Most of us spend more time inside when it's cold whether it's at your home, the mall, or the library.

And being in an enclosed space, in close contact with other people can open up more possibilities of germs being passed on from one person to another.

Also, viruses spread more easily through dry air. And since a lot of us have the heat cranked up, it's easier for those germs to spread.

The frigid temperatures and dry air can also irritate the mucus lining in your nose and throat which acts as a protective barrier from viruses entering your system.

Your best line of defense to weather the winter months and get through the flu season is to wash your hands often.

You should certainly do that before you eat, after going to the bathroom, and after being outside.
