What is National Smile Day?
National Smile Day on May 31 was established in 2018 by dentists Dr. Tim Stirneman and Jim Wojdyla to celebrate the power of a smile. Science backs it up: smiling releases endorphins, reduces stress, and can even lower blood pressure. Today, share your smile with the world.
How to celebrate
Mark the day with a poster made in Dayfeed — pick your favourite photo as the background, share it to your story or group chat, and set a reminder so you never miss it next year.
