I've heard about HeartMath for a long time but only recently decided to delve into it a bit more. It is a well researched approach to health and wellbeing (physical, emotional, spiritual, lifestyle...) I know a GP who recommends it to her patients and someone highly qualified in education who has trained to present its application to schools - children and teachers.
If you are interested in exploring the many free resources here's a link to one page: http://www.heartmath.org/free-services/solutions-for-stress/index-of-all-solutions.html From there you can see other free downloads in the side bar or go to the home page.
