Health involves both individual responsibility as well as community and state efforts. It is defined as activities individuals undertake to promote and maintain their own health, such as diet, exercise, medical checkups, and preventative measures. The community can support health through facilities, programs, and by actively participating in health planning, management, and evaluations. Both individual and community responsibilities are complementary. The state also has a role in directing health policy, making healthcare accessible, improving living standards and public health. International organizations foster cooperation between countries on health issues.
