The definition of health has changed over time. Early definitions focused on the body’s ability to function, as part of the biomedical perspective. “Health” was defined as “a state of normal functioning that may be affected by disease at any time.” An example of a health definition is “a state characterised by anatomically, physiologically, and psychologically integrity; the capacity to perform personally important roles in family, work and community; the capacity to cope with physical stress, biological stress, psychological stress and social stress.”
