You don't have to live in a cold climate to catch a cold. Colds are caused by airborne viruses that thrive in any climate, according to the Association of Mature American Citizens. But you are more likely to catch cold in the cooler climes come September not because of the weather, but because outdoor gatherings begin to give way to more intimate indoor affairs with people congregating in confined spaces.
In addition, the kids go back to school in the fall, no matter what the climatic conditions, and the classroom can be a breeding ground. So, when they get home or visit friends and family the cold virus has ample opportunity to tag a new victim.
You can reduce the prospects of catching cold by adopting the practice of regularly washing your hands thoroughly with warm soapy water for about 20 seconds, AMAC suggests. Use a hand sanitizer when washing is not convenient.
Another good idea is to get into the habit of sneezing and coughing into a tissue or into the crook of your elbow when you feel the urge in order to minimize the spread of the cold virus.
