Yawning is riddled with logical things around it, such as “it’s to help you get oxygen when your brain is sleepy,” or a “herd communication to relax,” and so on. That’s why it’s contagious. But how is it contagious? Some say it’s the sound of yawning that creates the trigger of contagiousness. Some say it’s visually seeing it.
But we often yawn when we don’t hear or see the other person prior to our yawn. Whoops…there go our current explanations!
There’s an easy solution to the question though –
Do deaf and/or blind people experience yawning contagiousness?
If yes, we’re missing something big in human biology. Maybe it’s ESP!?Probably not…
