There are some steps you can take yourself to avoid catching a cold. Contrary to popular belief, colds are not caused by exposure to severe weather. Colds are caused by viruses harbored in the body, and you’ re better off out on the ski slopes or even waiting for the bus on a snowy day than you are in a toast warm room, surrounded by friends, coworkers, or fellow students, who just may be passing the virus around. If you feel a chill when you’ re coming down with a cold, you’ re already sick. A chill is an early symptom; it’ s the cold that caused the chill, not the other way a-round. While the virus can spread through droplets propelled into the air when a cold sufferer coughs or sneezes, surprisingly, this is not the most common route of transmission. Numerous studies have now shown that the overwhelming majority of colds are " caught" by hand contact.
