Why Yawns Spread

A yawn is a reflex: a deep breath with the jaw stretched wide, followed by a quick exhale. People yawn when tired or bored, before sleep and after waking. Humans first yawn before birth, and many vertebrates, including fish and birds, yawn too.

Yawning is famously contagious. Seeing, hearing, reading about or even thinking about a yawn can trigger one, and people are more likely to catch yawns from close friends and family. Dogs can catch yawns from people, and researchers have studied links between contagious yawning and empathy.

Why we yawn is still debated. An old theory said yawning boosts oxygen, but tests did not support it. Another idea suggests yawning may help cool the brain by drawing in air and increasing blood flow, though research continues.
