But why we forget that the psychological aspect of every human being is also a part of a normal human being. So when the person is physically fit but has mental disorders, can we call him healthy? According to world health organization, health includes the physical, mental and social well being.

So to be healthy a person must have all the three of these factors at one and the same time. Physical, social and mental health are sometimes inter related. A person who is socially unwell may become mentally upset as well as may catch physical health problems due to unhygienic social conditions. There are numerous examples revealing the interrelated nature of the three.

To remain healthy one must be fit in all respects. Health can be maintained by a healthy diet and regular exercise. Exercising and diet helps keep a person protected against diseases and infections. Many state and non government organizations are working to improve and take care of the health of masses in modern era.

Every country is trying to provide its citizens with some kind of health facilities. Hospitals and health centers are contributing in this regard at national, community and town level. Developing countries are far behind in this regard. But to ensure the efficiency and effectiveness, the quality and quantity of health facilities must be improved in developing countries. Addressing the health triangle (physical fitness, mental health and social situation) could make the society better.

In developed countries health education is efficiently working to promote the methods by which health of people in a society could be ensured. But the developing countries are lacking in this sector.

Health education involves education regarding the maintenance and promotion of physical, mental, spiritual and social health of people. It equips individuals, communities and societies to take planned and effective health decisions for the promotion and well being of people in general.

It is the health educator who prepares plans regarding improvement and promotion of health facilities in the society.

The awareness campaigns are also designed by health educators for the masses so the people can enjoy better health using scientific and natural measures. Health education also helps counsel people regarding illness prevention and remedies.

Educational skills along with health expertise enable the health educators to enhance the health of others. The health educator decides his plans about health education strategies only after analyzing the need and knowledge level of a community regarding health. The communities which are developed but do not have water and those that suffer from environmental pollution will be educated differently in comparison to the people of less developed community that have many hygiene problems.

They may also do a research and evaluate after educating people about health to know the effectiveness of the efforts. In case of severe virus infecting masses in a society, like swine flu and bird flu, people can get useful information regarding prevention from health educators. The health educators motivate people for practicing what they learn through health education.
