Women More Prone To Contagious Yawning Than Men, Università di Pisa Study

A trio of researchers with Università di Pisa, in Italy has found via observational study, that women are on average twice as likely to yawn after seeing someone else yawn, than are men. In their paper published in Royal Society Open Science the team describes how they carried out their five year study of yawing habits in people and what they learned as a result.

Everyone knows that yawning is contagious—one person yawning spontaneously can cause another person in the vicinity to yawn even if they are not tired or sleepy.
