The planned and organized process of investing in education to achieve improvement in health of a population.
It involves consciously constructed opportunities for learning intended to facilitate changes in behavior towards a predetermined health goal.
Health education is one aspect of health promotion. It is to be found in schools, in work places, in health care premises and as part of community health services. It involves the use of mass media and may include the use of educational methods to change the knowledge and influence the attitudes of professionals and policy-makers. As much learning takes place in informal settings, people working in health education may be found working with youth groups, with community organizations, and with television, radio and press journalists. Techniques may include written educational materials or participatory approaches that include theatre, song and dance.
Nowadays health education and the broader field of health promotion are a standard and important part of any system of health services and are increasingly subject to assessments of their investment value.
