So, smile in private if you must, it will still boost YOUR mood. In particular, if one person observes another person smile, mirror neurons in that person's brain will light up as if he were smiling himself. As the WSJ's Sumatha Reddy reminds us, UCLA scientist Marco Iacoboni notes that our brains are wired for sociability. Thats because its an involuntary muscle thats controlled by the limbic system, or the emotional center of the brain. That's almost certainly a more potent mood changer.Īnd, there's another benefit to that Duchenne smile: if you do it in public, those around you will be lifted as well. When people fake a smile, the orbicularis oculi doesnt activate. And while the research details vary, I'd recommend going with a full, true smile that involves your eyes as well as your mouth. Falsified or fake smiles In a smile, the absence of movement in the outer part of the muscle that orbits the eye (orbicularis oculi pars lateralis, in Latin or AU 6 in FACS terms) distinguishes a fabricated smile from the genuine thing. Even though he was surrounded by his family members and celebrities from across the world Prince Harry looked lonely, bearing a fake smile to hide his discomfort. (Frowns have been shown to have the opposite effect.) The smile doesn't have to be based on real emotion - faking it works. But, a variety of research shows a measurable effect on one's emotional experience.ĭecades of research bear out the basic truth: your mood is elevated and your stress is reduced if you plaster a big smile on your face, even for a short period of time. This effect doesn't appear to be enormous - Botox won't turn people into walking automatons. Scientists report both a reduction in depression symptoms as well as weaker reactions to "happy" video clips.

That makes the face look smoother, but it also smooths out emotions to a small extent. These injections paralyze small, wrinkle-causing muscles around the eyes. As further evidence of the reverse linkage between facial muscles and emotions, Botox injections have been shown to dampen emotional responses.
