Why is it that when I yawn, without a doubt, the people around me yawn too?
It's a tough question because the reason why we yawn in the first place is a bit of a mystery. Not much research has been put into answering this question because yawning isn't really considered a problem.
There are many theories though. You yawn because you're tired, or when you're bored. And many people think you yawn because you need oxygen. But in 1987, Dr. Provine tested this theory and the results showed that yawning has nothing to do with needing more air.
Contagious yawning is a visual response. But not everyone catches the yawn bug. People who are more self-aware and empathetic tend to be more likely to catch yawns. You see them yawn, and subconsciously want to let them know you understand how they're feeling.
Another theory is that yawning is a way to stretch our lungs. Stretching and yawning often go hand-in-hand, and together help to flex our muscles and joints, increase our heart rate, and make us feel more awake.
Yawning is not a learned behavior - babies in the womb spontaneously yawn too. Want to see the video? read more
This is a 3-D ultrasound of a baby yawning in the womb.

watching that video made me yawn! I had heard that it was because your brain needed more oxygen and so it caused you to yawn.
1I heard that too, and it sounds like it makes complete sense. But Dr. Provine proved that to be a myth.
2Yeah, just reading this post and watching the video made me yawn like times.
3That kitty is adorable!
4I thought I was going to yawn but i did not...normally they are contagious
5So far I've yawned everytime I've seen a comment on this in Rush.
6In a college psychology class the professor read a 5 page passage with the word "yawn" in it about 50+ times (the story was not about yawning or falling asleep). By the time he was done, everyone had yawned multiple times and continued to do so for the rest of the 3 hour lecture...all from hearing the word.
7I yawned while I was reading this post too....
That's very interesting Tra!
8Oh God yes.. every time one of the cats yawn I yawn.. they're contagious as he11!

It's hilarious and so true.
12When I work out or am awalking home in the cold..when i get to the top of the hill I tend to do a large yawn and actually breath in and out two or three times before the "yawn" has ended. in this instance i ugess it is streching me? One time in highschool we were all on stage rehearsing a scene from a play..about 10 people. apprently one person yawned and without us knowing it, we each yawned all the way across in a line..the director feel out of his chair laughing so hard
I'm all in.
13That You Tube video was hysterical. Thanks for making me laugh Fit.
14hahaah. yawning is seriously the weirdest thing ever.
15Does anyone know what kind of kittens those are? Seriously, because they are so adorable and I'm thinking about getting a cat soon...thanks!
16I read that when you're tired, you make less effort to take deep breaths. So you take less air in. When you yawn, you inhale a lot more air than usual. So it's not exactly the brain needing more oxygen. It's more of your body. That's why you only yawn when you're tired.

I must say, adolescence is one hell of a ride!
And I also read that yawns are contagious. When you see someone yawn, you are alerted to the fact that there may not be enough air. So your brain prompts you to yawn!
