Answer to Question 1
1 .Alarm stage. When a stressor occurs, the body responds with the fight-or-flight response. Homeostasis has been disrupted. Several body systems are activated, especially the nervous and endocrine systems, to prepare the body for action. If the stressor subsides, the body returns to homeostasis.
2 . Stage of resistance. If the stressor continues, the body mobilizes its internal resources in an effort to return to a state of homeostasis, but because the perception of a threat still exists, the body does not achieve complete homeostasis. The stress response stays activated, usually at less intensity than during the alarm stage, but still at a level to cause hyperarousal.
3 . Stage of exhaustion. If the stress continues long enough, the body can no longer function normally. When chronic stress persists, organ systems may fail and the body breaks down in a variety of ways. Continuous stress that causes the body to constantly adapt can negatively impact your health.
Answer to Question 2
Today we face traffic jams and deadlines, loneliness and lack of money, arguments and examsdifferent types of challenges from our ancestors' and none of which demand that we run or fight. However, our bodies are unable to distinguish between life-threatening dangers and the more mundane problems of modern life. According to one doctor, we end up pumping high-energy chemicals for low-energy needs. The price is high: over the long haul you turn the energy inward and burn out..
