Definition of Health

health as a noun which refers to the general condition of the body or mind. Health is associated with the state of functionality of the body of an organism, especially the human body. There is no general agreement about any definition of health since health itself cannot be measured.

(1953) The United States President's Commission on Health Needs of the Nation states "Health is not a condition; it is an adjustment. It is not a state but a process. The process adapts the individual not only to our physical but also our social environments".
(1951) Talcott Parsons also conceptualized health as an ability to maintain normal roles. Parsons is an American sociologist and creator of the concept "sick role".
Over the decades, many health professionals and health theorists have provided their own definitions of health. Thus, health becomes an individual perception which can only be achieved through an on-going process of the person's aspect of the human body, mind, and feelings.
Maintaining Health
Effective strategies are needed in order to achieve and maintain good health. This includes stress management, health care, wellness programs, social activity, hygiene, and observations of daily living.
This can be attained by being able to effectively manage stress through thorough observations of daly living as well as utilizing health care and wellness programs that the government and independent sectors offers. Having a good social relationship with other people also helps promote and maintain health.
Though in some developing countries, people cannot easily maintain good health practices due to lack of government support in terms of health care programs and the lack of financial capacity to avail medical and health insurances.
Public Health
Dr. C.E. Winslow (1920) defines Public Health as "the science and art of preventing disease, prolonging life and promoting health through the organised efforts and informed choices of society, organizations, public and private, communities and individuals."
In relation to developing countries, The Public Health Care System attempts to improve and promote the health and welfare of citizens.
