Smiling is something almost all of us could do a bit more often. Past science shows that smiling – especially the kind of smile that involves the muscles around the eyes – creates a specific type of brain activation that’s connected to being in a happy mood. More recent research shows that even adopting this kind of smile, known as a “Duchenne smile” leads to lower heart rate levels and quicker recovery from stressful activities. Resilience and positive brain activity are maybe good reasons to grin a bit more in our lives, but there’s even a better reason.

The following video will show you exactly what that is.

Do this with your local grocery clerk, your neighbors, friends or the person walking by you on the street. Feel free to laugh in public, it turns out it’s an altruistic act. In fact, there’s an entire movement of Laughing Yoga that backs up this understanding
