I’ve noticed that yawning happens when I’m tired or bored, but why do we actually yawn? And why do I feel the need to yawn when I see someone else yawning?
In: Biology
I thought yawning was the primate way of announcing to the group that they’re safe and can go to sleep. That’s why it’s contagious.
I would swear I saw that in some nature documentary, but I may have made it up. 🤷♂️
