Chapter 12 Flashcards
Stress, Health, and Coping
stress
physiological and psychological experience of significant life events, trauma, and chronic strain
PTSD
a medical syndrome that includes symptoms of anxiety, sleeplessness, etc. frequently experienced by victims or witnesses of violence, abuse, natural disasters, war
Hans Selye
studied stress with rats, developing general adaptation syndrome
general adaptation syndrome
refers to the three distinct phases of physiological change that occur in response to long-term stress (alarm, resistance, and exhaustion)
alarm
body releases stress hormones
resistance
after a period of chronic stress, the body adapts to ongoing threat and tries to return to normalcy, while glucose and blood pressure continues to increase
exhaustion
body runs out of energy reserves and immunity, blood sugar levels decrease, leading to decreased stress tolerance, progressive exhaustion, illness, and collapse, organs begin to fail
HPA axis
a physiological response to stress involving interactions among the hypothalamus, pituitary, and adrenal glands
HPA response
begins when H secretes releasing hormones that direct the P gland to release ACTH, which directs the adrenal glands to secrete more hormones (like norepinephrine, epinephrine, and cortisol)
cardiac output
more blood being pumped
Holmes and Rahe stress scale
a measure of some everyday life events that might lead to stress
Social Readjustment Scale
measures whether stressful events might cause illnesses
daily hassles
our everyday interactions with the env that are essentially negative that also create stress
Meyer Friedman and R. H. Rosenman
among the first to study the link between stress and heart disease, finding that men are more likely to respond to stressors with negative emotions and hostility
tend-and-befriend response
a behavioural reaction to stress that involves activities designed to create social networks that provide protection from threats
Daniel Wegner
found that ppl can’t suppress simple thoughts
James Pennebaker
found that simply talking or writing about our emotions or reactions to negative events provides substantial health benefits
emotion regulation
ability to successfully control our emotions and can be trained
Walter Mischel
conducted an experiment with marshmallows, finding that effective self-regulation is important to positive characteristics and life success
stress’s effects on health outcomes
- personal (stressors’ damage on health are substantial)
- socioeconomic (differential exposure to stress can produce gender, racial, ethnic, and social class inequalities in health)
- sociopolitical (stressors proliferate over life and across generations, widening health gaps between privileged and non-privileged groups)
adrenaline
hormone that increases heart rate, blood pressure, and energy supplies
