Health psychology provides psychology"s contribution to behavioural medicine. Stressful event = appraisal (threat or challenge) = response (stress or aroused/focused) Those who are stressed but not depressed report being energized and satisfied with their lives opposite of the lethargy of those depressed but not stressed. Physical and emotional responses were a stress reaction. Stressors things that push our buttons: catastrophes. Prolonged stress takes a toll on our cardiovascular system. Medical interest in stress dates back to hippocrates; 1920s walter cannon confirmed that stress response is part of a unified mind-body system. All this prepares the body for the wonderfully adaptive response that cannon called fight or flight. On orders from the cerebral cortex (via the hypothalamus and pituitary gland), the outer part of the adrenal glands secretes glucocorticoid stress hormones such as cortisol.
