How stress makes it easier to catch the common cold

A new study has revealed that people who are stressed are much more likely to catch the common cold, Time Magazine reported.
The stress hormone cortisol - which is released during periods of anxiety - temporarily suppresses the immune system. So when the body encounters viruses or bacteria, it has much lower inflammatory response.
However, the researchers found that those who are chronically stressed are constantly releasing cortisol, making the immune system less responsive to the hormone. Instead of reducing inflammation, consistently high levels of cortisol actually increase the body's inflammatory response.
Cold symptoms that stressed people experience - such as coughing and sneezing - are more a side-effect of inflammation rather than the direct result of a cold virus, the researchers said.
