Cold & Flu myths
Colds are caused by cold weather.
No, they are caused by viruses. However, you might be more susceptible to colds in the winter months because you tend to go indoors in crowded environments where you are more likely to pick up other people’s viruses. Plus, there are some strains of cold viruses that thrive in the cold, and cold weather can dry out your sinuses, making them more vulnerable to infection.
