The Science Of The Yawn
Ever notice that you can't help yawning when the person your hanging out with keeps yawning?
This is a psychological effect that happens in response to seeing someone yawn.
In a recent study scientists have discovered that people yawn more around close family and friends.
Therefore, if someone you know well is yawning a lot you are way more likely to feel the effects yourself.
However, if a stranger is yawning, you may not feel like yawning at all.
Contagious yawning is still largely misunderstood.
Why does yawning spread from person to person?
Scientist are still continuing to solve this human mystery.
