Hans Selye (1907- 1982) was a Hungarian endocrinologist, first to give a scientific explanation for biological stress. Hans Selye explained his stress model based on physiology and psychobiology as General Adaptation Syndrome (GAS).His model states that an event that threatens an organismâs well-being (a stressor) leads to a three-stage bodily response: Stage 1: Alarm.onclusion. Hans Selye's theory profoundly influenced the scientific study of stress. Stress is a state produced by a change in the environment and the nature of the stressor is variable.
This response can cause damage to the body, however, it is a survival mechanism that can save the person's life. This explains why prolonged stress causes such a wide variety of physical symptoms.
