According to Hans Selye, the wear and tear exerted by life on the body is referred to as "stress." Selye is well-known for his work in the field of stress research, particularly his development of the General Adaptation Syndrome (GAS), which describes the physiological changes the body goes through when adapting to stressors. He argued that stress is a natural response to demands placed on the body and that it can have both positive and negative effects on health, depending on how it is managed. In his model, he outlined three stages: alarm, resistance, and exhaustion, highlighting how prolonged exposure to stress can lead to significant health issues.
