History of World Smile Day

We are all familiar with the smiley face symbol. It has become an essential part of how we communicate with others. 

It was Harvey Ball, an artist, and designer from Massachusetts, who created the smiley face in 1963. The symbol quickly grew in popularity, and everyone was using it to communicate, in ad campaigns, and on television. The smiley face was everywhere. It wasn't long until the image spread throughout the world, and there wasn't one person who didn't recognize it.

This rise in popularity concerned Harvey Ball, who didn't want his creation to be too commercialized. That took away from his original intention when he created the smiley face: to have an image that symbolized cheerfulness and kindness.

To stop that from happening, Ball came up with the idea for World Smile Day in 1999. He wanted people to dedicate at least one day out of the year to being kind to each other and exchanging smiles with everyone, regardless of politics, religion, or differing opinions. After his death in 2001, the Harvey Ball World Smile Foundation took over the organization of this day. 

Science-backed Benefits of Smiling

  • There is scientific evidence that just taking a moment to stop and smile can instantly make you feel better.
  • Smiling releases endorphins, which are neurotransmitters that make you feel pleasure. This can happen even when you smile for no reason, as the same messages get sent to the brain triggering a feeling of happiness, which then triggers you to smile even more!
  • Did you know that smiling helps to improve your cardiovascular health? This is because when you smile, your facial muscles contract which increases blood flow to the brain.
  • Smiling and laughing often can significantly improve longevity by reducing stress, enhancing social relationships, and promoting overall happiness. Studies show that a strong sense of humor is linked to a lower risk of heart disease, infections, and other age-related health issues.

A bonus fact is that making other people smile has the same effect since helping others makes you feel happier. So share a few smiles today!

"We shall never know all the good that a simple smile can do"

-Mother Teresa

Smiling is often described as contagious, and this is true. People naturally imitate the faces of those around them, it is the same instinct that allows us to empathize and experience what others are feeling. So if you smile, you will find that other people around you, either consciously or subconsciously, will also start smiling. 

How to Celebrate World Smile Day

Today is all about doing things that will make you feel good but are also kind to others. You can do this by trying to make other people smile, whether it is your friends and family or a complete stranger, by telling them a joke or doing a random act of kindness for them.

If you live near Worcester, Massachusetts, the home of the smiley face, you can attend one of the events that the World Smile Foundation organizes.
