World Smile Day 2022: All you need to know

World Smile Day is marked on October 7 every year.

It was first created by Harvey Ball, developer of the smiley face, in 1963.

After his death in 2021, his foundation created the slogan "improving the world, one smile at a time".

At the time of his death, Ball's net worth was estimated to be between $1 million to $2.5 million.

World Smile Day is aimed at encouraging smiles and acts of kindness around the world.

The theme of World Smile Day for 2022 is ‘Do an act of kindness. Help one person smile!’.

Smiling helps in releasing tiny molecules called neuropeptides from the brain to help fight stress.

Smiling also helps in boosting immune systems and release natural painkillers and serotonin.
