Is Yawning Contagious?

Updated on September 17, 2012

According to research performed at New York State University, between 40 and 60 percent of the population seems to find yawning contagious.

Researchers from the State University of New York in Albany tested people to find out why some are susceptible to contagious yawning and deduced that self-aware or empathetic people are more likely to catch yawns.

Also, Ronald Baenninger, a professor in the psychology department at Temple University in Pennsylvania, has conducted a study to see if the contagion works between species. He and his students went to the zoo to observe whether humans would yawn when the animals did. A few people yawned in response to a lion's yawn, but the lion never replicated the humans' behavior, Baenninger said. There is some evidence that when one ape yawns, others will too.

Dr. William Broughton, director of the Sleep Disorders Center at the University of South Alabama Knollwood Hospital, said the action of a mouth opening is not what compels others to yawn, Broughton said. Studies have demonstrated that showing someone a photo of a wide-open mouth does not induce a yawn. Also, holding a hand over the mouth while yawning doesn't prevent it from being contagious, Broughton said.

A scientific look at the issue is this: The Finnish government recently funded a brain scanning study that shows yawn contagion is largely unconscious. Wherever it might affect the brain, it does not affect the known brain circuitry for consciously analyzing and mimicking other people's actions; this circuitry is called the "mirror-neuron system."

The researchers found that yawning seems to activate at least one brain area, which is called the superior temporal sulcus. Even more relevant was the apparent deactivation of another brain area, the left periamygdalar region. The more strongly a participant reported wanting to yawn in response to another person's yawn, the stronger was this deactivation.

Studies on physical brain activity related to yawn contagious seems to be inconclusive.

Some scientists believe yawning came to be a method to communicate levels of alertness to each other and coordinate sleeping times.

It's also been suggested contagious yawning could be a result of an unconscious herding behaviour, a way to communicate to those around us, similar to when flocks of birds take flight at the same time.

      That was really interesting. I love yawning. It's comforting, and cosy.

      I know that there is on the market a book of photo's of lot's of children yawning.. it's marketed for bedtime stories to get the children sleepy.

      I thought that was a great idea.

      I think the Author came from a sleepy town, but woke up rich over night. And good on that writer, or would that be photographer, which ever. brilliant mind.

      Another great Hub.

      Yawning is undisputably contagios, I have never seen any even vaguely convincing arguments explaining why, I do however have my own theory( not based on any research as such but follows accordingly.)

      What is yawning? people have tried to explain it's immediate effects etc. but I think people should also think about what Yawning is most comparaable to, my answer is ........Vomiting. The action a person makes when yawning is immensly like that of a person vomiting, essentialy wretching, (yawn too much repeatadly and you will even feel slightly sick.) Now suppose it's a feature of our brains means we vomit when other things around us are seen to vomit, this is a useful behavioral feature because animals living in groups might well share the same immediate food source (same deer or meat etc.) If the meat is tainted and one of them detects this and vomits, it might be beneficial to the others if they vomit and not risk any contamination themselves.

      This is just my own theory, I don't neccesarily believe it, it's just an Idea I had that made some sense and appeared to be better than many possible solutions

      My doctor informed that yawning is contagious. It appears to be an accepted medical fact.

      Interesting information. I had also heard that the "contagious" part of yawning comes from empathy. Whenever I "catch" someone else's yawns, I think about how empathetic I am. Ha.
