Question 2

According to the text, The nature of the autonomic nervous system is important to our understanding of stress. The sympathetic division was designed to deal with emergencies that could be resolved relatively quickly. Our ancestors either escaped that lion or they did not. Worrying about far distant dangers is a luxury that human beings did not have until quite recently. Do you agree or disagree with this statement? Explain your reasoning. What are the physical consequences of worrying about far distant dangers?

What will be an ideal response?

Answer to Question 2

ANSWER:
Students could agree with the text, which states as follows: Unfortunately, we now have the opportunity to worry about upcoming exams, next months rent payment, what to do following graduation, and if we have sufficient funds for retirement.... Because most modern stress is unavoidable, it is essential that you practice good stress management, such as maintaining excellent dietary and sleep habits, exercising regularly, and maintaining strong social networks.

Alternatively, students might disagree and view the lives of our ancestors as containing significant, ongoing stressors, such as the stress of producing enough food by hunting or agriculture, malnourishment, starvation, dangers presented by animals, accidents, natural disasters, infections, illnesses, unexplained epidemics, death in childbirth, keeping children safe, infant and child mortality due to illness or injury, the lack of health care, interpersonal and tribal strife, etc. Most people likely had a shorter life span than people of the present day, which may have limited the impact of chronic stress or may have been related in part to chronic stress.

Whenever a person identifies something as a significant threat, the sympathetic division goes into action. Sustained sympathetic activation depletes the body of resources at the same time that the parasympathetic division is unable to store new resources. If left unchecked, sympathetic division activity can lead to fatigue and wear and tear on internal organs.
