Live Longer And 9 Other Benefits of Smiling

What happens when you encounter a good friend on the street? Your first reaction is probably to smile. But what is the science behind that smile?

When you see your friend, neuronal signals travel from the cortex of your brain to the brain-stem. From there, the cranial muscle carries the signal further towards the smiling muscles in your face. Once the smiling muscles in your face contract, there is a positive feedback loop that now goes back to the brain and reinforces your feeling of joy.

Very simply, smiling makes you feel good. More than just contracting the muscles in your face, it helps to generate positive emotions within you. Smiling also reduces the stress that your body and mind feel, almost similar to getting a good night’s sleep.
