While many people find yawning to be contagious, with some studies suggesting that around 40-60% of people will respond to a yawning trigger, a significant portion of the population remains immune. Uncovering why you can't catch a yawn is a fascinating journey into the complex interplay of our social wiring and biological makeup.

While yawning is a universal and evolutionary conserved behavior observed in nearly all vertebrates, starting as early as 11 weeks in human fetuses, it's also a reflex that many attempt to stifle. But what happens if you don't open your mouth when you yawn? Physically possible but often unsatisfying, the stifled yawn prevents the full physiological process and leaves you with an incomplete sensation.

Over five hundred years before Christ, Hippocrates suggested that yawning was a way to expel bad air from the lungs, a theory long since disproven.

While yawning is often described as an involuntary reflex, some people believe they can control it at will. So, how come I can yawn on command?

According to research, about half of adults will yawn contagiously after seeing or hearing someone else yawn, highlighting a deep, empathetic connection. So, how do you trigger a yawn and what are the surprising reasons behind this seemingly simple human reflex?

The average yawn lasts about six seconds, a natural and involuntary reflex that many people try to suppress in social situations.

Yawning is a complex and often misunderstood reflex, with research indicating that seeing, hearing, or even reading about yawning can trigger one.
