Stress Coping and Health Flashcards
Stress
negative emotional experience with predictable responses and directed towards altering or accommodations
mind and body relationship with personal contextual factors
environmental balance and maintaining/not maintaining homeostasis
Stress Response
stressor knocks the body out of homeostasis, then the body tries to maintain homeostasis
Walter Cannon
1932 dude determined fight or flight where sympathetic and endocrine system prep for survival
stress in health
Hans Selye
1930s where stress is scientific with one definition and defined General Adaptation Syndrome to explain those physical conditions and changes
found that with his biochemist buddy
General Adaptation Syndrome GAS
alarm phase is reacting to the stressor
resistance phase is where the body is coping and fighting the stressors
exhaustion phase is the optional avoiding that one where the body is depleted of those resources
GAS Problems and Critiques
limited psychosocial factors
reducing importance of appraisals
assumes stress has the same response all around
Pituitary Gland Purpose
secrete corticosteroids increase protein and fat metabolism increase energy access inhibit antibodies formation and inflammation regulate sodium retention
Adrenal Medulla Purpose
increase HR and RR decrease digestion dilate pupils increase blood flow to muscles vasodilation
Homeostasis
optimal levels, number and amount for any measure in the body that is achieved through systematic and local regulatory mechanisms
Allostasis
physiological system fluctuates in response to stress that is context dependent and has multiple methods
coordinating body wide changes and regulation in anticipation of and following stress
Chronic Stress
causes decreased immune functioning, inhibit growth, at increased risk for illness, and impact reproductive systems
Allostasis Load
build up of stress response over time due to repeated exposure to stress and causes premature aging
Primary Appraisals
how fucked are we?
Secondary Appraisals
can we deal?
Physiological Effects of Stress
increased lipids
