How does general adaptation syndrome relate to stress?

The correct answer highlights that general adaptation syndrome (GAS) describes a three-phase response to stress, which is foundational to understanding how humans physiologically and psychologically react to stressors.

GAS was developed by Hans Selye and consists of three distinct stages: the alarm reaction, the resistance stage, and the exhaustion stage. In the alarm reaction, the body recognizes a stressor and initiates a fight-or-flight response, activating the sympathetic nervous system. The resistance stage follows, where the body attempts to adapt to the ongoing stressor, balancing stress responses with recovery. If the stress continues beyond the body’s capacity to cope, it enters the exhaustion stage, which can lead to burnout or adverse health effects due to prolonged stress.

This model illustrates the biological and psychological responses to stress, emphasizing that stress is not just a single reaction but rather a process that can evolve over time. Understanding these phases can help professionals in mental health identify the impacts of stress on individuals and guide interventions accordingly.
