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

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

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

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.
