His initial inspiration for GAS came from an endocrinological experiment in which he injected mice with extracts of various organs. He at first believed he had discovered a new hormone but was proved wrong when every irritating substance he injected produced the same symptoms (swelling of the adrenal cortex, atrophy of the thymus, gastric and duodenal ulcers). This, paired with his observation that people with different diseases exhibit similar symptoms, led to his description of the effects of "noxious agents" as he at first called it. He later coined the term "stress", which has been accepted into the lexicon of various other languages.
Selye in the preface to Stress, acknowledges Claude Bernard (who developed the idea of 'milieu intérieur') and Walter Cannon's 'homeostasis'. Selye conceptualized the physiology of stress as having two components: a set of responses he called the general adaptation syndrome, and the development of a pathological state from ongoing, unrelieved stress.
Selye discovered and documented that stress differs from other physical responses in that stress is stressful whether the one receives good or bad news, whether the impulse is positive or negative. He called negative stress distress and positive stress eustress. The system whereby the body copes with stress, the hypothalamus-pituitary-adrenal system, was also first described by Selye. He also pointed to an alarm state, a resistance state, and an exhaustion state, largely referring to glandular states. Later he developed the idea of two 'reservoirs' of stress resistance or alternatively stress energy.
He wrote Stress without Distress (1974), The Stress of Life (1956), and From dream to discovery; on being a scientist (1964). He worked as a professor and director of the Institute of Experimental Medicine and Surgery at the Université de Montréal.
In 1968 he was made a Companion of the Order of Canada.
