Smiling is a universal sign of happiness that crosses all borders. It's also free, makes you feel good, and is contagious and easy to share. Here are even more reasons you should turn that frown upside down.


Smiling helps your heart and mood

Smiling can help reduce your heart rate and lower stress when compared to those who maintain a straight-face, discovered researchers from the University of Kansas. Apparently, the facial muscles that are used for smiling trigger your brain for happiness and calm—even if you’re faking it. “It’s not just that our brains are happy,” explained lead researcher Sarah Pressman, PhD, an assistant professor at the University of Kansas, “If you’re happy, you perceive stress differently and feel less threatened.” Here are more reasons to smile every day.

Smiling makes you more trustworthy

In a University of Pittsburgh study from 2012, researchers wanted to see if there was a connection between a person’s perceived level of trustworthiness based on the intensity of their grin.

Smile because there’s a World Smile Day

Worcester, Massachusetts-based commercial artist Harvey Ross Ball created “World Smile Day” in 1999. The annual day would land on the first Friday in October. Believe it or not, Harvey Ball created the “Smiley Face,” also known as the “Happy Face” or “Smiling Face,” in 1963. He created it to boost morale at the State Mutual Life Assurance Company in Worcester, where he was employed. (Check out the strange story behind his creation.) Ball created the annual event as a reminder for everyone to stop taking themselves so seriously all the time and be happy every once in a while. The Harvey Ball Foundation—a non-profit charitable trust, which was created after his death in 2001 at age 79—continues to celebrate every year to “make as many people as possible aware of World Smile Day by using the web, social media, and your help to encourage smiles and acts of kindness around the world.” Here are more unknown and wacky days to make you smile.


Smiling can help you see the “big picture”

Smiling can help you gain perspective on making better decisions in your life and work, according to a 2008 study in the Journal of Consumer Research. “We argue that by signaling that a situation is benign, a positive mood allows people to distance themselves psychologically from the situation,” reports the study’s co-authors Aparna Labroo of the University of Chicago and Vanessa Patrick of the University of Georgia. “Psychological distancing results in taking a broader perspective, or seeing the big picture,” leading to “higher level thinking.” Here are more strategies on how to make a good decision.


Smiling can reduce pain

When you use your facial muscles to smile, it sends a signal to your brain to release serotonin and endorphins, which are the chemicals associated with feeling good and happy. These chemicals can also reduce the perception of pain.
