Can Bundling Up Indoors Help Stave Off Colds?

Staying indoors when the temperature drops won't help -- in fact, it may make you more susceptible to catching a cold. While cold weather appears to produce more colds, experts say it’s really the surrounding environment that support ills. The reason: Colds are caused by viruses. And when it’s cold outside, more people remain indoors in confined, stale-aired spaces, making it easier to spread sickness-causing germs than it is outdoors. Viruses also tend to sail more smoothly through dry air -- a common occurence during cold weather when we crank our indoor heat. While you can’t avoid being indoors in cold weather, one way to fight viral exposure is with frequent hand washing. You should also make an effort to keep your hands away from your nose and mouth where viruses can easily multiply and spread.
