Information:  - Health is the level of functional and metabolic efficiency of a living organism. In humans it is the ability of individuals or communities to adapt and self-manage when facing physical, mental or social changes. The World Health Organization (WHO) defined 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." 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". Other definitions have been proposed, among which a recent definition that correlates health and personal satisfaction.  - Aaron Antonovsky (19 December 1923  7 July 1994) was an Israeli American sociologist and academician whose work concerned the relationship between stress, health and well-being (salutogenesis).  - The World Health Organization (WHO) is a specialized agency of the United Nations that is concerned with international public health. It was established on 7 April 1948, headquartered in Geneva, Switzerland. The WHO is a member of the United Nations Development Group.

Antonovsky was born in the United States but emigrated to Israel in 1960 after completing his PhD at Yale University . For a time he held positions in Jerusalem at the Israeli Institute for Applied Social Research and in the Department of Medical Sociology at the Hebrew University of Jerusalem / Hadassah . During this period his early work emphasized social class differences in morbidity and mortality . In 1972 he helped establish the medical school at Ben - Gurion University of the Negev , and held the Kunin - Lunenfeld Chair in Medical Sociology . During his twenty years in that Department , Antonovsky developed his theory of health and illness , which he termed Salutogenesis . This model was described in his 1979 book , Health , Stress and Coping , followed by his 1987 work , Unraveling the Mystery of Health . The books were acclaimed among health scholars as an important contribution to understanding the relationship between health and illness . A key concept in Antonovsky 's theory concerns how specific personal dispositions serve to make individuals more resilient to the stressors they encounter in daily life . Antonovsky identified these characteristics , which he claimed helped a person better cope ( and remain healthy ) by providing that person a `` sense of coherence '' about life and its challenges ; Helen Antonovski developed a scale ( Orientation to Life Questionnaire ) in 1987 to measure it . Recent research in psychoneuroimmunology has supported the relationship between emotions and health contained in Antonovsky 's theory . Antonovsky died in 1994 , but research using his theory continues by social scientists .  - Salutogenesis is a term coined by Aaron Antonovsky, a professor of medical sociology. The term describes an approach focusing on factors that support human health and well-being, rather than on factors that cause disease (pathogenesis). More specifically, the "salutogenic model" is concerned with the relationship between health, stress, and coping.
