Why is yawning contagious?
Answer
Hearing or seeing yawning triggers the same brain regions
Yawning is contagious because seeing or hearing someone yawn activates the same neural pathways in the brain that produce yawning. This is linked to mirror neurons and empathetic responses, which is why it happens even when we're not tired.
💡 Did you know?
People with autism spectrum disorder are less likely to catch yawns, suggesting contagious yawning is tied to empathy circuits in the brain.
