Did you know that we start yawning while we’re in the room? Research has shown that yawning begins for the fetus around 11-weeks. Contagious yawning usually begins around 1 or 2 years old. In a recent study, it was also determined that we have a very limited capability of resisting a yawn when someone nearby yawns. The urge to yawn is increased when we’re told not to yawn. An average yawn lasts 6 seconds with men yawning longer than women.
