10 Intriguing Reasons Why Yawning Is So Contagious (Backed by Science)
2. Empathy and Mirror Neurons

Closely related to social bonding is the role of empathy in contagious yawning. Research indicates that individuals with higher levels of empathy are more susceptible to contagious yawning. This connection is believed to be mediated by mirror neurons, specialized brain cells that fire both when an individual performs an action and when they observe the same action performed by another. Mirror neurons facilitate the understanding of others' emotions and actions, making yawning a form of empathetic response. This neurological foundation underscores the idea that yawning is not just a physical act but a shared emotional experience.
