The document describes the three stages of stress: 1) Alarm stage - the initial reaction stage where the body releases hormones like adrenaline to prepare for fight or flight. 2) Resistance stage - the body has responded to the stressor and the person continuously experiences stress. This is also called the gate toward burnout. 3) Exhaustion stage - the final stage where the person slowly loses energy to manage stress and may experience health problems if stress is not addressed.
