Contagious smiling (and frowning and scowling and so on) is the basis of reading others' emotions and registering how you should, in turn, feel.

When you're smiling, the whole world smiles with you

We tend to mimic the smiles or frowns of others because it helps us better understand what other people are feeling, allowing us to respond appropriately.

Evidence shows that an instinct for facial mimicry allows us to empathize with and even experience other people's feelings.

“Facial mimicry certainly plays some role, and perhaps a key role, in understanding other people’s emotional states,” Dr. Kevin Ochsner

A person's ability to recognize and "share" others' emotions can be inhibited when they can't mimic faces, even from something as simple as long-term pacifier use.

When you smile,you are creating a symbiotic relationship that allows both of you to release feel-good chemicals in your brain, activate reward centers, make you both more attractive, and increase the chances of you both living longer, healthier lives.

First stage: You see an expressive face You need to know what the expression means so you can react effectively.

Second stage: You simulate the facial expression Simulation uses the same areas of your brain that cause your facial expressions- it may therefore cause you to mimic the expression.

Third stage: The simulation tells you how it feels to make that expression The context or your knowledge about the expresser may have an influence.

This quick, automatic, and unconscious process allows you to connect the subtle emotion signals of others to your own emotion experiences.

Smiling makes us happier Smiling triggers a reduction in stress-enhancing hormones and increases the production of mood-enhancing hormones.

Even forcing a “fake” smile when you’re not truly feeling it has been shown to reduce stress and result in more positive feelings.

Genuine smiles might help people see eye-to-eye during interactions. People who often make genuine smiles may have an easier time convincing others to adopt their goals.
