"Health" is defined by the World Health Organization (WHO) as: A state of complete physical social and mental well being, and not merely the absence of diseases or infirmity.
"Health Promotion" is defined by the WHO as: The process of enabling people to increase control over and improve their health.
In practice, this process involves: Any combination of health education (methods for health behavior changes), + environmental change (creating an environment that is conducive to health), + change in health policy (by any policy makers and not only health services), + empowerment (and participation) of the community in improving it's health.
