Why do people yawn?

It is not just people who yawn. Even cats and dogs do. Sometimes we yawn when we are feeling sleepy or bored. It is believed that yawning makes us more alert. During yawning, the facial muscles and neck muscles are stretched. This helps to improve blood circulation making us feel alert. Another theory holds that people yawn when their bodies need more oxygen. Yawning is very infectious.
