Remember how your mother warned you that spending time outside in the winter could lead to catching a cold?
Let’s see ... how to put this. Mom was wrong.
“Being out in the cold doesn’t impact your immune system,” says Jessica Grimes, MD, a family medicine doctor at Duke Primary Care Wake Forest. “You have to be exposed to the cold virus to get a cold.” Grimes says the cold virus is more prevalent in late winter, which may have led moms throughout the ages to proffer this advice.
Hand washing is the most important thing you can do to protect yourself from colds in the winter and all year long.
