Health promotion — is the combination of educational and environmental supports for actions and conditions of living conducive to health. The purpose of health promotion is to enable people to gain greater control over the determinants of their own health. 
Health promotion represents a comprehensive social and political process, it not only embraces actions directed at strengthening the skills and capabilities of individuals, but also action directed towards changing social, environmental and economic conditions so as to alleviate their impact on public and individual health. Health promotion, and the associated efforts put into education, community development, policy, legislation and regulation, are equally valid for prevention of communicable diseases, injury and violence, and mental problems, as they are for prevention of non-communicable diseases.
