According to new research reported on at Science Daily, social rejection upsets your heart. When you feel rejected, your heart rate drops for a brief time.
Researchers, Bregtje Gunther Moor, Eveline A. Crone, and Maurits W. van der Molen of the University of Amsterdam and Leiden University in the Netherlands were interested in discovering the ways in which social pain can actually affect you on a physical level.
In the study individual participants were shown photos of unknown people who had rated whether or not they liked the participants, based on the participants own photos. Surprisingly, the participants heart rates fell in anticipation before they found out how they were rated by others.
"Unexpected social rejection could literally feel 'heartbreaking,' as reflected by a transient slowing of heart rate," conclude the researchers in their report.
