A smile is free, and everyone understands it. People smile in every country in the world. But a smile does more than you think!
Babies Smile Early
Babies start to smile at the people around them when they are about six weeks old. Nobody teaches them. They just do it. Even children who cannot see smile.
We Smile Back
When someone smiles at you, it is hard not to smile back. Try it! Smile at a friend and watch their face. Scientists say that our brain copies the faces we see.
Smiling and Stress
Some studies show that smiling can help a little when you feel stressed. In one study, people who smiled during a hard task had a calmer heart after the task.
People Like Smiling Faces
People think that a smiling person is friendly and kind. A smile can help you make new friends, and it can help at work and at school, too.
So smile at your family, at your friends, and even at yourself in the mirror. It is free!
