The meaning of health has evolved over time. From a biomedical perspective, early definitions of health focus on the body's ability to function. Health was seen as a normal working condition that could be affected by illness from time to time. An example of such a definition of health is: "A state characterized by physical, physical, and psychological integrity. The ability to play a personally valuable family, work, and social role. Physical, physical, biological, psychological, and social Ability to deal with stress ". Then, in 1948, in stark contrast to previous definitions, the World Health Organization proposed a more broad definition: linking health to physical, mental, and social well-being, and not just disease. And the absence of weakness. "Although some people welcomed the definition as inventive, it was also criticized for being ambiguous, overly broad, and not measurable. For a long time, it was set aside as an impractical ideal, and most health discussions returned to the practicality of the biomedical model.
