You can get a cold year-round, but most people consider the winter months to be common cold season. We are more likely to get colds when the weather is cold and we spend more time indoors sharing germs with other people. The viruses that cause colds also spread more easily in colder, drier air. Generally, this means cold season starts sometime around September and ends sometime around April in the United States.
However, this doesn't mean the cold weather itself makes us sick. Prolonged exposure to cold temperatures can cause very serious illnesses like hypothermia, but there is no strong evidence to show that the cold itself can give you a cold. Only exposure to a virus that causes the common cold can do that.
There are several reasons why colds are more common during cold season.
- People spend more time indoors and closer to each other during the winter.
- Children are in school and sharing germs with many more children than they do during the summer.
- The viruses that cause the common cold spread more easily in cold, dry air.
- Our nasal passages are drier during the winter (due to drier air), allowing cold viruses to take hold and make us sick better than they can during the spring and summer months.
However, just because colds are more common when the weather is cold, doesn't mean colds are caused by cold weather. It's the viruses that make us sick, not the temperature outside.
How to Avoid Colds During Cold Season
Wash Your Hands
Do you know how to wash your hands? Are you sure you're doing it right? Such a simple act is an incredibly important part of keeping yourself and those around you healthy. We touch our faces thousands of times a day and we touch things in our environments even more often. Washing those germs off your hands is essential to keeping them out of your body.
Cover Your Cough
If you are sick and coughing, use your elbow to cover your mouth when you cough. When you cough into your hands, you just spread the germs onto everything you touch and then to anyone else who might touch those things after you. Changing how you cover your cough really isn't that difficult and it makes a big difference in the spread of germs.
