The Link between Emotions and Rheumatoid Arthritis

Researchers at Penn State University have found that emotions themselves can act as stressors to create inflammation and pain in the body. In this study they found a link between emotions and rheumatoid arthritis (RA). 

“We often think of emotion as a consequence of stress or pain, but our findings suggest that under certain circumstances negative emotion or complex, mixed emotion can function as a stressor itself, and one which can promote inflammation,” said Jennifer Graham-Engeland, associate professor of biobehavioral health and lead author of the manuscript.
