10. Contagious Yawning Occurs Most Often With Friends And Family Members
Have you ever noticed that you don’t yawn as often when strangers yawn? If you are sitting on a crowded bus or subway and someone yawns, you are less likely to yawn in response. This may be due to the empathy aspect of contagious yawning.
The explanation is likely that you have more empathy with friends and family members, with whom you have strong emotional bonds. When you hear the familiar sound of one of them beginning to yawn, your empathy response is much stronger, making you more likely to yawn contagiously.
