Being mindful means being acutely aware of what is happening now—rather than drifting into the past or musing about the future—without emotionally reacting to these ongoing events. Maintaining a focus on the present is associated with a variety of improvements to physical and mental health. Practicing mindfulness can also enhance key aspects of intellect—in particular, the ability to pay attention. In this video, mindfulness experts at the University of Miami lead you through a short mindfulness exercise that can help you to assume this mental state more often—and reap its rewards.
