Sometimes your joy is the source of your smile, but sometimes your smile can be the source of your joy. — Thich Nhat Hanh
An interesting research report, by Tara Kraft and Sarah Pressman, will soon be published in Psychological Science. Their research speaks directly to well-being, psychological and physical, and the link between these two spheres. The researchers wondered about the effects of smiling on physiological recovery from stress.
The innovation of their research was that they deliberately manipulated whether participants were smiling or not — making this a true experiment — and further took steps to avoid “demanding” hypothesized responses from these participants*. via Psychology Today
