Why Do We Yawn And Why Is It So Contagious? (The Science Will Surprise You)
You've tried to stop it. You can't. The moment someone near you yawns, your jaw drops, whether you like it or not. But why? And what does it say about your brain?
In this episode of The Doculethes Vault, we go deep into the science of yawning — from the surprising brain-cooling theory, to the mirror neuron system that makes yawning one of the most contagious social behaviours known to science.
What you'll discover:
Why was the "low oxygen" theory of yawning debunked?
How does your brain use yawning as a built-in cooling system?
Why empathy determines how susceptible you are to contagious yawning?
Why do dogs yawn when their owners yawn?
If you yawn during this video, that's actually a good sign.
