Washington DC Post (Internet / Print) 05/29/06 http://www.washingtonpost.com/wp-dyn/content/article/2006/05/29/AR2006052900757.html It takes only a sneeze, a cough or a handshake to spread cold or flu germs from one person to another. But emotions can be transmitted even more easily, faster than the blink of an eye. Research has found that emotions -- both upbeat ones like enthusiasm and joy, and negative ones like sadness, fear and anger -- are easily passed from person to person, often without either party's realizing it. If you're the receiver, you may not know what exactly happened, just that you feel differently after the encounter than you did before. A study at the University of Texas Medical Branch in Galveston found that depression was highly contagious among college roommates, with those who sought a lot of reassurance and support from their depressed roommates being particularly vulnerable to catching the feeling.
