Yawns are a mirror neuron reaction. I can't tell you exactly why but when you see someone yawn you have to also.
Also, yawns are a symptom of fatigue, antidepressants, and some kidney medicines.

yeah, because whe someomeone else yawns, it send the message to your brain to do the same. technically they aren't contagious, they just (usually) are a case of monkey see, monkey do in an unstoppable way.

CALLING ALL CURIOUS PEOPLE: THE REASON WHY WE YAWN, AND WHY IT IS CONTAGEOUS.

IT IS DUE TO HUMAN INSTICT. IT IS THE MOTION OF OPENING YOUR MOUTH WIDE. WE DON'T REALISE WHY WE DO IT, BUT IT'S NATURAL.ITS A MIRROR NEURON REACTION. ITS THE UNCONSIOUS PART OF OUR BRAIN KICKING IN. THE REASON WHY PEOPLE YAWN IS BECAUSE SOMETIMES WITHOUT YOU KNOWING, YOUR LUNGS GET LAZY AND DONT TAKE IN ENOUGH AIR, PARTICULARLY WHEN YOUR TIRED. SO, THE YAWN TOPS YOU BACK UP AGAIN. WHEN YOU'RE BORED YOU DONT TAKE IN AS MUCH AIR AS YOU SHOULD, SO YOUR BREATHING SLOWS DOWN THEN, TOO. THAT IS WHY PEOPLE YAWN, AND WHAT IT MEANS.

I just think that its when we see someone do it,our brain automatically reacts and thinks that it has to make us do it too.^^

When they yawn, they take your oxygen, and then you yawn to get revenge and take their oxygen!

When you yawn, it means the brain needs mais oxygen. When you see someone else yawn, your brain responds that it needs mais oxygen as well and you yawn... >.>

it depends on if you have an emotional connection with the person who previously yawned. if you do, something in your brain sorta triggers and you yawn, almost like youre answering their call or something like that.

FreeAwesomeness said:
Yawns are caused por too much carbon dioxide in the lungs. Seeing someone yawn, or thinking about yawning (I'm yawning right now) I think makes you remember that you're breathing. Once you realise that, it can sometimes become harder to breath.
...To be honest, I have no idea what I'm composição literária here, I'm just putting up some aleatório stuff that sounds vaguely scientific.
