General Adaptation Syndrome is the three-stage process that depicts the physiological changes the body experiences when under pressure. The first stage is the alarm stage, which gives a burst of vitality. In the second stage, known as the resistance stage, the body endeavors to oppose or adjust to the stressor. The last stage is known as the exhaustion stage in light of the fact that vitality is exhausted.
According to Hans Seyle's <span>general adaptation syndrome (GAS) model, when faced with and responding to stressors, individuals and animals go through three stages: Alarm, Resistance and Exhaustion. During the Alarm stage, individuals have their sympathetic nervous system (or fight-or-flight response) activated. This means that they aroused with a burst of energy to either fight the threat or flee from it. In Nancy's example, when she encountered the rattlesnake, she experienced the alarm stage of the GAS model, where she was prepared to flee from the rattlesnake. </span>
