Yawning: The Contagious Phenomenon Unveiled
Why does yawning spread among people?
Ever felt an uncontrollable urge to yawn after seeing someone else doing it? You're not alone. Contagious yawning, a peculiar behavior shared by humans and several other species, is a fascinating subject that's been catching the attention of researchers worldwide.
"Contagious yawning is as common as laughter, and it's highly infectious," says Christine Blume, a psychologist and sleep researcher at the University of Basel, in her conversation with ntv.de. Yet, the reasons behind this phenomenon remain a mystery.
Understanding Yawning: More Than Just a Reflex
Yawning, a reflexive behavior characterized by a deep breath, wide mouth opening, and exhalation, is still a topic of research for scientists. Various theories suggest that yawning improves oxygen supply to the brain or cools it down. However, these theories struggle to explain why yawning is less frequent during physical activities when brain oxygen consumption is higher.
Distinguishing between spontaneous yawning and contagious yawning is crucial. Spontaneous yawning, which even newborns exhibit, is thought to have a biological function. Contagious yawning, on the other hand, seems to develop alongside social abilities and isn't considered essential for survival.
The Social Connection: Contagious Yawning Explained
Research demonstrates that there's a social component to contagious yawning. Studies show that participants who watch videos of people yawning yawn significantly more than those who watch videos of people smiling. This social connection could be linked to empathy, with more empathetic individuals being more susceptible to contagious yawning.
Mirror Neurons and Yawning: A Complex Relationship
Mirror neurons, brain cells that activate when an individual performs an action and observes someone else do the same, play a significant role in contagious yawning. When we see someone yawn, our mirror neurons simulate the action internally, potentially leading to actual yawning.
However, the exact role of mirror neurons in contagious yawning remains unclear. Some research suggests that they facilitate empathy, allowing us to mimic others' behaviors, including yawning. But it's essential to remember that other factors, such as alertness and non-verbal communication, might also contribute to contagious yawning.
The Search for Answers: Continuing the Quest
As Blume points out, the quest to understand why yawning is contagious is still ongoing. Research is driven by hypotheses, and scientists are gradually unveiling the intricate web of neurological mechanisms that underlie this peculiar behavior. Whether it's empathy, social connection, or something else entirely, the answer could change our understanding of human behavior and social cognition.
In conclusion, contagious yawning is a fascinating subject, and research continues to uncover its mysteries. The activation of mirror neurons plays a pivotal role, but the exact reason behind contagious yawning remains elusive, opening up new avenues for exploration in the fields of psychology and neuroscience.

- Most animals and many other vertebrates yawn as well, including dogs, monkeys, and fish. Dogs can also be infected by human yawning, especially by their owners. Even fish yawn, but only spontaneously to draw water into the throat.
- Recent studies have shown that not only biology but also inanimate agents, such as androids, can induce contagious yawning in animals like chimpanzees. This indicates that the visual cue of yawning can be enough to trigger this behavior, even if the source isn't biological.```
