What happens in your body when you yawn or swallow?
When you feel sleepy, you yawn. When you feel bored, you yawn. The kid next to you yawns. You yawn, too--even if you are wide awake and having a good time. So why are you yawning? Let's check it out. Your body needs oxygen. You get oxygen by breathing in air. Your body also needs to get rid of carbon dioxide. When you breathe out, this carbon dioxide is carried out of your body. Your brain makes sure you have the right amount of oxygen and carbon dioxide in your body. If you have too much carbon dioxide in your body, your brain tells your mouth to open. It tells your throat to tighten. And it tells your chest to take a deep breath. In other words, your brain makes you yawn. Oxygen rushes in. Carbon dioxide rushes out.
Why do other people yawn when you yawn?
Well, in my science class this old dude was experimenting that. Someone yawned on stage and 55% of the audience yawned too. When he noticed that he started experimenting. He thought it might be the way your mouth moves when you yawn, so he made a video clip of a persons mouth yawning and played the sound affect of a yawn, but then only 5% of the people yawned. So, no one actually knows why. This guy also experimented other things about yawing, but never found his answer.I read in a book it was a group thing for you to tell the group you're tired and everyone to have a rest. See the book why is snot green.
