A genuine smile is not just a simple facial expression, it is a powerful emotion that can be felt even from a distance.

In fact, a recent study conducted by the University of Grenoble in France found that real smiles are visible from far away and can be easily distinguished from fake ones.

What is a real smile?

A real smile, also known as a Duchenne smile, is a genuine expression of happiness and joy. It occurs when the zygomatic major muscle, which is located in the cheeks, is contracted, causing the corners of the mouth to turn up and the eyes to crease.

A real smile is a sign of inner happiness and can lift the mood of those around you.

The difference between real and fake smiles

People often fake smiles to be polite or to hide their emotions. However, fake smiles can be easily detected as they do not involve the contraction of the eye muscles.

A fake smile, also known as a non-Duchenne smile, only involves the mouth and can appear forced and unconvincing.

The study conducted by the University of Grenoble found that people can easily identify a genuine smile from a distance of up to 30 metres.

This is because real smiles involve the contraction of the eye muscles, which creates a distinctive crease around the eyes. The study involved participants viewing a series of photographs of people displaying either real or fake smiles. The results showed that people were able to detect real smiles with an accuracy rate of 86%.

The benefits of a real smile

A genuine smile can have a positive impact on your physical and mental health. When you smile, your brain releases feel-good neurotransmitters like dopamine and serotonin, which can boost your mood and reduce stress levels.

Smiling also triggers the release of endorphins, which are natural painkillers and can reduce feelings of anxiety and depression.

Smiling can also have social benefits, as it can help to build relationships and create a positive first impression. People are naturally drawn to those who smile, as it signals confidence, happiness and approachability.
