What makes us yawn? Yawning is cause of boredom and other theorize it that we need to stretch our neck muscles. Many researcher belief and agree yawning is simply way of our body to compensate for less oxygen in our blood stream.

Every cell in our body needs continual supply of oxygen. When you breathe you take the air to supply into our lungs and pass through to the blood so that the oxygen can carry throughout our body. Normally when we exhale, we get rid the waste carbon dioxide. If you can recall when you are bored or just sitting around, you tend to breath slowly than normal because our body doesn’t get all the oxygen we needs. Sometimes we are not getting rid of the carbon dioxide in our body. Our brain senses this and extra breath is called yarn. We always open our mouth when we yarn because you can breath much more air through our mouth than through to our nose. The air isn’t clean because its not filtered through the nose. A yarn is design to take in a lot of air quick, clean or not. Also animals do yarn, for the same reason we do. If you want to avoid yawning you should take a deep breath whenever you feel to yarn. If you like the oxygen you take can easily flow through your body sit comfortably or chew a gum to stimulate your mouth muscles to prevent from yawning.
