Mindfulness has been practiced for 2,500 years—but only recently has science tried to measure it. In this episode, Esther Adams translates cutting-edge research into plain English: What exactly is mindfulness? Can a questionnaire capture it? Is it different from attention? Does it actually predict better emotion regulation and health? And how does mindfulness develop—with or without formal meditation? Clear, practical, and a little playful, this episode helps you use the science without getting lost in the weeds.
