chapter 2 Flashcards
stress
general physical and emotional state that accompanies a stress response
stressor
mental states or events
stress response
physical and psychological reaction
physical response to stress is a
protection mechanism to a perceived threat
autonomic NS
acute
sympathetic, parasympathetic
sympathetic
fight, flight, freeze
parasympathetic
rest and digest
endocrine system and stress
acute and chronic
hormonal chemical messages
fight, flight, freeze activate the
adrenal glands
adrenal glands secrete
cortisol, epinephrine
physiological response to fight, flight, freeze
- HR, BP, respiration increase
- hearing, vision become more acute
- Liver releases more sugar into bloodstream (glycogenolysis)
- Increased perspiration
- Digestion & peristalsis cease
return to homeostasis
perceived threat is diminished
sympathetic response is withdrawn
sympathetic response is withdrawn
physiologic changes revert to baseline
cognitive response to stress
appraisal or perception of situation
reduce the magnitude of response
how does cognitive response reduce magnitude of response
successful prediction, perception of control
psychological response to stress
emotion related
anxiety, depression, fear
psychological responses are impacted by
personality, education, cultural background, gender, lived experience
4 stress level types
underload, optimal, overload, burnout
optimal level of stress
moderate level
stress underload
not challenged enough to improve
inactive, laid back
overload stress
exhaustion, fatigue, challenges become stressors that impair physical and emotional health
burnout
anger, anxiety, panic, breakdown
universal and predictable response pattern to all stressors
general adaptive syndrome
eustress
initiated by pleasant stressor
distress
initiated by unpleasant stressor
stages of GAS
alarm, resistance, exhaustion
alarm stage (GAS)
fight, flight, freeze
makes body vulnerable to disease or injury by mobilizing it to cope with a crisis
resistance stage (GAS)
with continued stress the body develops a new level of homeostasis to cope with the added stress, increasing resistance to illness
exhaustion stage (GAS)
results in the depletion of resources that leave the body vulnerable to disease
allostatic load
wear and tear on the body that results from the long-term exposure to repeated or chronic stress
