In a fascinating study entitled “Induction of empathy by the smell of anxiety,” published in the journal of the Public Library of Science (PLoS) in 2009, researchers discovered “The chemosensory perception of human anxiety seems to automatically recruit empathy-related resources.” Smelling chemical signals from the sweat of anxious subjects elicited an empathic response, even when the smell was below the threshold of consciousness in half the subjects.
Empathy, in fact, has concrete and measurable therapeutic effects in others.
