Module 39 Flashcards
stress
process of perceiving and responding to certain events that we appraise as threatening or challenging; arouses and motivates us to conquer problems
momentary/minimal stress
can have positive effects - mobilizes immune system for fending off infections and healing wounds; increase spirituality, self-esteem, and purpose; build resilience
chronic stress
can have negative effects - burnout, risky decisions and behaviors, decline in health; triggers blood vessel inflammation, potentially causing heart disease and depression; people who experience social threats are more prone to inflammation
catastrophe
unpredictable, large-scale events (including relocating to another country); can cause paralyzation by fear
acculturative stress
mental and emotional challenge of adapting to a new culture (due to culture shock); decreases over time due to increased meaningful social interactions
stressors
events that we appraise as threatening and challenging
significant life changes
life transitions; many happen during young adulthood; can heighten when trying to take on too many things at once
daily hassles and social stress
some can shrug off, some can’t; can increase when facing prejudice (stress > in marginalized groups)
fight-or-flight response to stress
Cannon; epinephrine and norepinephrine are released due to arousing events (emotion, cold, lack of O2), triggering the sympathetic nervous system and the fight-or-flight response; “executes plan”
glucocorticoid stress hormones
cortisol; released by adrenal glands in response to cerebral cortex urges to stress; combat inflammation and mobilize glucose to use for energy, leading to exhaustion
increased levels of glucocorticoids effects
permanent damage to hippocampus neurons, smaller hippocampi, fatty acid build up on walls of blood vessels (reduced blood flow and increased risk for heart attack), and decreased enzyme production and bloodflow to stomach and intestines (increased vulnerability to bacterial infections)
general adaption system (GAS)
Seyle; body’s adaptive response to stress; alarm reaction, resistance, exhaustion
phase 1 of GAS
alarm reaction; sympathetic nervous system is activated; increase of heart rate, blood goes to skeletal muscles, faintness of shock
phase 2 of GAS
resistance; increase of temperature, blood pressure, and respiration; adrenal glands pump hormones into bloodstream; w/o relief from stress, body’s reserves decrease over time
phase 3 of GAS
exhaustion; become more vulnerable to illness
