Why Do We Yawn When We See Someone Else Yawning?

Have you ever seen someone yawn and suddenly felt your own mouth open wide? This is called contagious yawning, and it happens because our brains are like tiny mirrors. When we see another person yawn, a special part of our brain lights up as if we were the ones doing it. Scientists think this helps us connect with each other. It is not just about being bored or tired. Even babies who have never seen anyone else yawn might catch it from their parents later on. This ability shows that we care about what others are feeling. It is a secret handshake between our minds, helping us feel closer to the people around us.
