Why a broken heart really does hurt – Telegraph
Posted August 22, 2009on:
Researchers have found a genetic link between physical pain and social rejection, which means that breaking up with a partner really can be painful.
Psychologists at the University of California, Los Angeles say the human body has a gene which connects physical pain sensitivity with social pain sensitivity.
The findings back the common theory that rejection ‘hurts’ by showing that a gene regulating the body’s most potent painkillers – mu-opioids – is involved in socially painful experiences too.
