Feeling "blah," and got the sniffles? If you do, and if you're also suffering from stress, chances are that it will be harder for you to kick the symptoms of your cold. New research published in the Proceedings of the National Academy of Sciences found that stress makes the symptoms of the common cold more intense and harder to get rid of because it makes inflammation in the body stick around longer than when stress is not present.
But wait a minute: stress doesn't cause colds, viruses cause colds, right? That's right. But when you are stressed out, you overproduce cortisol, making the immune system incapable of turning "off" the inflammation switch. The bottom line is that if you're exposed to a cold virus while you are also dealing with chronic stress — say at work or in your marriage — you are much more likely to get the cold and suffer from more intense symptoms than if you were not stressed out.
"The symptoms of a cold are not caused directly by the virus, they're caused by the inflammatory response to the infection," said Sheldon Cohen, a professor of psychology at Carnegie Mellon University in Pittsburgh and lead author of the study. "You want to produce enough of inflammation to fight off the infection, but not so much that you experience cold symptoms."
The findings also suggest that other illnesses, such as asthma, cardiovascular disease, and autoimmune disorders may be similarly affected by stress. Do yourself and your runny nose a favor and find a way to ease your stress — at least until the next cold comes along!
