According to "How strong is the mind-body link", severe stress has a effect on health because it reduce activities of immune cell, caused illness. Kevin Tracey says that "One branch of the vagus nerve connects the brain to a key regulator of immune functioning"(¶ 4) and his team also found that "stimulating the vagus nerve decreases inflammation..., including cancer."(¶ 5). On the other hand, they suspect that other nerve-immune links have the effect of "turning up" inflammation.
When I read his article, actually I know about effect of stress, but I don't know how it relates to the body. I think that every part in our body has a strong connection and it's difficult to understand them. However, this experiment's result is very important because researchers can continue their study to make the treatments for patients. For example, they can directly reduce inflammation by giving the drug that affects the vagus nerve. I think that this is a effective way to cure illness.
