Document Summary
Ch. 4 october 8: how stress affects health. Diathesis stress model: the view that people"s vulnerability to a physical or psychological disorder depends on the interplay of their predisposition to the disorder (the diathesis) and the amount of stress they experience. What is it about stress that leads to illness: a direct route, resulting from changes stress produces in the body"s physiology or an indirect route, affecting health through the person"s behaviour: stress, behaviour, and illness. People who experience high levels of stress tend to behave in ways that increase their changes of becoming ill or injured. Stress impairs sleep and the resulting inattention and carelessness: psychoneuroimmunology. This field focuses on the relationships between psychosocial processes and the activities of the nervous, endocrine, and immune systems. People"s emotions, both positive and negative, play a critical role in the balance of immune functions. Positive emotions can also affect immune function, giving it a boost.
