Ch 15-Stress, Coping and Health Flashcards
stressors
specific events/chronic pressures that place demands on a person or threaten their well-being
stress
the physical and psych response to internal or external stressor
health psychology
subfield concerned w the ways psych factors influence causes and treatment of physical illness and maintenance of health
chronic stressors
sources of stress that occur continuously/repeatedly
- effects can accumulate/be long-lasting
- linked to environments
fight-or-flight response
emotional and physiological reaction to an emergency; increases readiness for action
-brought about by the HPA axis
HPA axis
(hypothalamus, pituitary and adrenal)
-H activates P (which is important in releasing hormones) which activates A (just above the kidneys) to release catecholamines (which increase the sympathetic nervous system (increase heart rate and breathing, primes muscles to react and act)) and cortisol (which makes more glucose available in the bloodstream to make more energy)
general adaptation syndrome (GAS)
- 3 stage physiological response to stress that appears regardless of the stressor encountered
1. alarm phase mobilizes resources
2. resistance phase uses resources to combat and cope with stress
3. exhaustion phase in which reserves are depleted and the immune system may begin to weaken
immune system
complex response system that protects the body from bacteria, viruses, other foreign substances; can’t respond as well when high levels of stress are experienced
lymphocytes
white blood cells that produce antibodies that fight infection
psychoneuroimmunology
study of how the immune system responds to psychological variables (stressors)
glucocorticoids
hormones that flood the brain and wear down the immune system’ caused by stressors
Type A behaviour pattern
tendency toward easily aroused hostility, impatience, sense of time urgency, and competitive achievement
-indvs tend to have more cardiovascular health problems, possibly bc of their high bodily response
Primary appraisal
determining whether is stimuli is or isn’t stressful
secondary appraisal
determining whether you have control over or can handle the stressor, which affects how well you cope
PTSD
disorder characterized by chronic physical arousal, recurrent unwanted thoughts/images of the trauma, avoidance of things that call the traumatic event to mind
-smaller hippocampus may predispose indv to PTSD
