Why is Yawning So Contagious?
Posted by Guy Pirro on 9/1/2017 7:17 AM
Do you yawn when you read an Astromart News posting? I hope not. But if you do, does your spouse or significant other also yawn even though he or she is across the room? Why is that so?

Researchers at the University of Nottingham suggest that the human propensity for contagious yawning is triggered automatically by primitive reflexes in the primary motor cortex -- an area of the brain responsible for motor function.
