Which model is primarily associated with the stages of stress response?

The General Adaptation Syndrome (GAS) is the model primarily associated with the stages of stress response because it outlines a clear sequence that the body undergoes when faced with stress. Developed by Hans Selye, this model describes three stages: the alarm reaction, the stage of resistance, and the stage of exhaustion.

In the alarm reaction stage, the body recognizes a stressor and initiates a fight-or-flight response, which includes physiological changes like increased heart rate and adrenaline release. During the stage of resistance, the body attempts to adapt to the ongoing stress, using resources to cope and maintain stability. If the stress continues for an extended period, the body enters the stage of exhaustion, where its ability to cope diminishes, leading to potential negative health consequences such as fatigue, burnout, or illness.

This model provides a comprehensive framework for understanding how prolonged exposure to stress can affect physical and mental health, distinguishing it from the other models that focus on different aspects of stress or psychological responses.
