Document Summary

Chapter 9 physical disorders and health psychology. Leading causes of death early 20th century: influenza, pneumonia, diphtheria, tuberculosis, gastrointestinal infections. Describing a psychosomatic disorder with an obvious physical component gives the impression mood/anxiety disorders are not a component. Stress due to economic uncertainty considered a cause of plummeting life expectancy. Shift in focus from infectious disease to psychological factors called second revolution in public health. Two related new fields: behavioural medicine. Knowledge derived from behavioural science is applied to prevention, diagnosis and treatment of medical problems. Interdisciplinary field, work closely together: health psychology. Study psychological factors important to promotion/maintenance of health. Stress originally an engineering term (strain on a bridge when heavy truck drives across) We focus on it as the physiological response of the individual stressor. Neurohormones act like neurotransmitters, carrying brain"s messages throughout body. Corticotrophin releasing factor (crf) is secreted by hypothalamus, stimulates the pituitary gland which activates adrenal gland which secretes the hormone cortisol.
