--According to Selye, excess stress results in breakdowns. The human body has a sensitive physiology that deals with stressful situations by igniting us into “high gear.” The responding pattern to stress is known as the GAS. All extended stressors go through three adaptive stages, including alarm, resistance, and exhaustion.
--1st Stage: Alarm reaction—excites the autonomic nervous system, the release of adrenaline (stress hormone), and physical anxiety.
--2nd Stage: Resistance—the adaptation and coping of stress due to activation of the “thinking brain” (cerebral cortex), which leads to the examination of the unfolding of events, evaluation of alternative solutions, and investigation of attempted coping strategies.
--3rd Stage: Exhaustion—results from a lack of coping and limited personal resources that leads to resistance breaking down and high levels of activation can no longer be sustained. This can lead to organ system damage, immune system breakdown, depression, or PTSD.
