With more than 200 viruses known to cause it, the common cold can seem unavoidable, especially if you have kids. But there are steps you can take to reduce your chances of being infected.

Wash hands. The most effective method for preventing infection by a cold virus is to scrub your hands with soap and water frequently – especially when you have been out in public, or in proximity to another person suffering from symptoms.

Don’t touch. Avoid touching areas of your body that can absorb the virus into your system – your eyes, nose and mouth. It can be difficult to remember, especially if you are seized with a sudden itchy eye; hence, the importance of hand washing.

Wipe down. The National Institute of Allergy and Infectious Diseases notes that “rhinoviruses can survive up to three hours outside the nasal passages on inanimate objects and skin.” They suggest cleaning surfaces in your home or office space with a disinfectant when someone is sick with a cold, to prevent the spread of infection.

Sleep well. Researchers at Carnegie Mellon University found that those who slept more than seven hours each night were less likely to succumb to colds. Their sleepy counterparts saw a three-fold increase in colds, compared to those who got enough z’s. Give your body an immunity boost from a good night’s rest.

Exercise regularly. Studies show that exercise does more than make you strong. It can also reduce the occurrence (and intensity) of colds. Dr. David Nieman, a professor of health and exercise science at Appalachian State University, says that his study recorded a 43% reduction in sick days due to colds, and a reported 40% drop in symptoms experienced, among those who walked briskly for 35-45 minutes, 5 days per week.

Cold season is here. But there are ways to keep viruses at bay.
