What's the reason for yawning all the time

First, the reason for yawning is physiologically thought to be caused by hypoxia. It is said that when the oxygen concentration in the lung is detected to be lower by the tissues around the lung, people will yawn to breathe in more air.

Second: it is also said that yawning is caused by boredom. If people are tired of something, they will yawn and express their indifference with body language. But the activity of the paraventricular nucleus of the hypothalamus, known as the brain's "yawning center", is often associated with the most interesting things.

Third, yawning is handed down from primitive ancestors to show teeth and warn others. The snake crouching in the grass and motionless often yawns before moving; the hippo in the water yawns first and then comes out of the water.
