The World Health Organization (WHO) defines health as "a state of complete physical, mental and social well-being, and  not merely the absence of disease or infirmity".   Immunizations from various diseases have improved health worldwide.

What it means to be healthy can vary from culture to culture and is often connected with advances in technology. In some cultures, larger body sizes are seen as a sign of healthiness as it indicates an individual has a preponderance of food. In other cultures, largess is more closely associated with unhealthy lifestyles (e.g., lack of exercise, poor eating habits, etc.). Advances in technology have also expanded the idea of what it means to be healthy. What are understood today to be healthy practices were not emphasized prior to clear understandings of disease and the contributions of lifestyles to health.

Health care (or healthcare) is an industry associated with the prevention, treatment, and management of illness along with the promotion of mental and physical well-being through the services offered by the medical and allied health professions. The sociology of health and medicine is concerned with the distribution of healthcare services globally, in particular inequalities in healthcare, and how conceptions of health have changed over time.

                       Hans Selye. Stamp-Canada2000      - Congress on Stress. Stamp-Hungary, 1997


HANS Selye (1907-1982) - Father of the stress-concept


Hans Hugo Bruno Selye was a Canadian endocrinologist of Austro-Hungarian origin. He graduated from the German University, in Prague (1929). Some commentators consider him as father of the stress-concept, and the first to demonstrate the existence of a separate stress syndrome or General Adaptation Syndrome (GAS). However, Walter Canon had described it earlier, in his article, fights or flight syndrome (1914), and had coined the term ‘homeostasis to external environment”.


For Selye, initial inspiration came from experiments in which he injected mice with various organ extracts and believed that he had discovered a new hormone. He was proved wrong, when every irritating substance that he injected, produced the same manifestations: - adrenal enlargement, gastrointestinal ulcerations and thymico-lymphatic involution (atrophy of spleen and thymus). He considered that ‘noxious stimuli” produced this pathological triad, and developed the theory of stress, that attained wide popularity It also incited controversy that persists till day. He described it as nonspecific response of the body to any demand. The hypothalamus-pituitary-adrenal axis system was first described by Selye, whereby body copes with stress. He outlined three distinct phases in the evolution of GAS: - alarm reaction (fight or flight), stage of resistance (adaptation), and stage of exhaustion.


The knowledge of GAS and HPA axis system made it possible, to begin gauging the role of stress in our lives. Multitude of researchers, continue to toil in the wake of his ideas, even twenty five years after his death  . Stressors elicit both pituitary-adrenocortical and sympatho-adrenomedullary response. Karel Pacak et al (1998), measured arterial ACTH. norepinephrine. and epinephrine, in conscious rats after hemorrhage, injection of I V. insulin or S.C. formaldehyde, cold, and immobilization. Results were inconsistent with Serve’s doctrine of non specificity and unitary stress syndrome, and consistent with the concept that each stressor had its own central neurochemical and peripheral neuro endocrinological “’signature” Immobilization elicited the largest increase in levels of all three compounds. Most researchers now believe that psychosocial stressors result in suppression of immune system and were and tear of several systems Selye worked as Professor Director of the Institute of Experimental Medicine and Surgery at the University de Montreal Nominated for the Nobel Prize, he was also made Companion of the Order of Canada.
