Health

Health is the level of functional and metabolic efficiency of a living organism. The World Health Organization (WHO) defined human health in its broader sense in its 1948 constitution as “a state of complete physical, mental, and social well-being and not merely the absence of disease or infirmity.”[1][2] This definition has been subject to controversy, in particular as lacking operational value, the ambiguity in developing cohesive health strategies, and because of the problem created by use of the word “complete”, which makes it practically impossible to achieve.[3][4][5] Other definitions have been proposed, among which a recent definition that correlates health and personal satisfaction.

An alternative approach focuses on avoiding definitions, which demand precise descriptions of the term. Instead, following a three-year global conversation, convened by Alex Jadad[8][9], “health” has been conceptualized as the ability to adapt and self manage when individuals and communities face physical, mental or social challenges.

The definition of health has evolved over time. In keeping with the biomedical perspective, early definitions of health focused on the theme of the body’s ability to function; health was seen as a state of normal function that could be disrupted from time to time by disease. An example of such a definition of health is: “a state characterized by anatomic, physiologic, and psychological integrity; ability to perform personally valued family, work, and community roles; ability to deal with physical, biological, psychological, and social stress”.

Then, in 1948, in a radical departure from previous definitions, the World Health Organization (WHO) proposed a definition that aimed higher: linking health to well-being, in terms of “physical, mental, and social well-being, and not merely the absence of disease and infirmity”.[12] Although this definition was welcomed by some as being innovative, it was also criticized as being vague, excessively broad, and was not construed as measurable. For a long time, it was set aside as an impractical ideal and most discussions of health returned to the practicality of the biomedical model.
