1. The state of the organism when it functions optimally without evidence of disease or abnormality. 2. A state of dynamic balance in which an individual's or a group's capacity to cope with all the circumstances of living is at an optimum level. 3. A state characterized by anatomical, physiological, and psychological integrity, ability to perform personally valued family, work, and community roles; ability to deal with physical, biological, psychological and social stress; a feeling of well-being; and freedom from the risk of disease and untimely death. [A.S. haelth] From the Old English hal, meaning whole, the term has been variously defined among health specialists. In 1948, the World Health Organization described health as "a state of complete physical, mental, and social well-being and not merely the absence of disease." This definition was, in turn, criticized as unquantifiable. In 1984, WHO advanced a revised statement that any measure of health must take into account "the extent to which an individual or a group is able to realize aspirations and satisfy needs, and to change or cope with the environment." Health in this sense is seen as a "resource for everyday life." Health also involves an ability to perform within society, and to accommodate stresses, whether physical or mental. From an ecological viewpoint, the relative health of a group is evaluated according to whether that group might sustain its existence over time without major disruption to its own way of life or to the environment within which it functions.
