We yawn when we are tired, bored, or in need of increased oxygen intake. Yawning may help to regulate brain temperature and improve alertness by increasing blood flow and oxygen levels. It's also a social behavior; seeing someone else yawn can trigger yawning in others as a form of empathy or connection.
