Mindfulness training is a technique that shows great promise as a tool for the development of healthy and constructive management of negative emotions. Mindfulness can reduce anxiety, depression, and stress. It has been used with success in populations as diverse as cardiac patients, prison inmates, police officers, and children. It incorporates deep breathing, heightened attention to one’s internal state, and the acceptance of internal discomfort. One can observe one’s own thoughts without identifying with them and acting on them.
