Yawning is mysteriously contagious, but scientists believe it’s linked to empathy and social bonding.
When you see someone yawn, your brain mirrors their behavior, a response controlled by the same part of the brain that processes emotions.
Studies show that people are more likely to “catch” a yawn from family or close friends than from strangers. Even some animals, like dogs and chimpanzees, yawn when they see humans do it.
