Yawning is usually a sign that your brain is not getting enough oxygen. When this happens you will feel tired and start to yawn. It is believed that the yawning is an attempt to take in more oxygen.

Ok you yawn from lack of oxygen you tend to breath slower when your board or tired so you have to yawn to catch up but you can also yawn after running or anything that causes you to loose oxygen.

Yawning is a sign of lack of oxygen to your brain. By yawning, we force the air into our lungs and therefore into our brains.
