The adaptation syndrome model, proposed by Hans Selye in the 1930s, describes the body's physiological response to stress in three stages: alarm, resistance, and exhaustion. In the alarm phase, the body detects a stressor and initiates a fight-or-flight response. During the resistance phase, the body attempts to adapt to the stressor, maintaining a state of heightened alertness. If the stress persists and the body cannot adapt, it enters the exhaustion phase, leading to decreased function and potential health issues.

How many stages?
The alarm stage of the general adaptation syndrome (GAS) model is called the "alarm reaction." It is the initial response to a stressor, where the body recognizes a threat and activates the fight-or-flight response. This stage triggers the release of stress hormones, such as adrenaline and cortisol, leading to physiological changes like increased heart rate and heightened alertness. This reaction prepares the body to confront or escape the stressor.
General adaptation syndrome is used to describe how someone's body short and long term reaction to stress. This is to see how someone is able to handle their stress.
Hans Selye is the psychologist credited with proposing the general adaptation syndrome. This theory describes the body's response to stress as progressing through three stages: alarm, resistance, and exhaustion. It has had a significant impact on understanding the physiological effects of stress.

Dr. Hans Selye was the psychologist who discovered the General Adaptation Syndrome.
General adaptation syndrome, or GAS, is a term used to describe the body's short-term and long-term reactions to stress. There are three stages the alarm reaction, the stage of resistance, and the stage of exhaustion.
