Why Stress Might Make You Sick, Carnegie Mellon University Study

A new study involving the common cold may help explain why stress, which dampens the immune system, seems to trigger inflammation in many people. That would appear contradictory, because the immune system creates inflammation (for example, the redness around a wound) to help the body heal. But the research suggests that high and long-term levels of stress contribute to inflammation. In turn, the inflammation can lead to conditions such as heart disease, asthma and autoimmune disorders, in which the immune system turns against the body.
