While colds and the flu commonly appear during winter months, the truth is that they are not the result of being out in the cold. According to the American Lung Association®, these infections prevail because it's the time of year when viruses usually spread across the country. Viruses and infections spread when many people stay indoors and are in closer contact with each other—including each other's germs. To best avoid catching a cold or flu, limit your time spent with sniffling friends and wash your hands frequently, especially before you eat and after you use the restroom. And since being out in the cold may give you a chill, but not a cold, remember to bundle up before enjoying the great outdoors!
