For most of us, catching someone else’s yawn is almost automatic. But why does it happen, and why can we sometimes yawn just from hearing one, reading about it or even thinking about it?

On Is It Just Me?, Lynlee Foo and producer Alexandra Parada unpacks why yawns are contagious, how the behaviour may help us synchronise with those around us, and what it can tell us about the way humans and other social animals interact. Featuring insights from Elisabetta Palagi, Associate Professor of Ethology, Department of Biology, University of Pisa.
