WK 6 - STRESS, COPING & HEALTH Flashcards
Stress
A physical, cognitive, emotional and behavioural reaction of an individual to any circumstance (real or perceived) that threatens, challenges or exceeds the individual’s coping resources
Stressors in modern society
Catastrophes (war, earthquake, famine), significant life changes (leaving home, getting married), daily hassles (road works, assignments, work)
Functions of stress (+)
When short-lived or perceived as a challenge, stressors can have positive effects (fight or flight) > arousal motivates us to solve problems
Functions of stress (-)
Extreme/prolonged stress can also be maladaptive > prolonged (chronic stress) or excessively severe stress increases our risk of illness and health problems
Stress response
Stress response (fast) is a fight or flight response marked by the outpouring of adrenaline and noradrenaline from the inner adrenal glands, increasing heart rate and respiration rates, mobilising sugar/fat and dulling pain
Theories of stress
1) General adaptation syndrome (Hans Selye) > response based view of stress and concentrates more on the biological aspects of the stress response
2) Lazarus’ view (Lazarus and Folkman) > interactionist approach
General adaptation syndrome (Selye)
Response is the same regardless of the stimuli, whether it is physical or emotional, viewed as positive or negative
Lazarus’ view (primary appraisal)
Remember stress refers to any circumstance (real or perceived) that threatens a person’s well-being > e.g. a new job could be exciting (opportunity) or scary (potential failure) according to your primary appraisal
Lazarus’ view (secondary appraisal)
How well do you expect to cope > availability of resources is weighed up vs demands (what is the likelihood that I will overcome this?)
Developmental influences
Perception/reports of stress typically decrease with advancing age
Symptoms of stress
1) Physical > muscular aches, pains, nervous tic, breathing changes, butterflies, sweating, constipation, itchy, grinding teeth, frigidity
2) Psychological > fear, anxiety, panic, worry, depression, guilt, anger, low confidence, memory lapses
3) Behavioural > drug use, alcohol use, over/under-eating, aggression, stuttering, crying, nagging, reduced work performance
Stress and illness
1) Psychoneuroimmunology > how our thoughts and feelings impact the brain, and in turn influence hormones and immune system functioning
2) Psychophysiological illness > a stress related illness, differs from ‘psychosomatic’ which implies that the physical symptoms are not real
3) Stress trigger immune suppression > fewer disease-fighting lymphocytes (WBC), stress linked to infection, asthma, chronic fatigue, headaches, insomnia, heart disease
Stress and colds
Development of colds > 47% in stressed and 27% low stress
Stress and healing
Stress can impact healing > wounds heal 40% more slowly in stressed students before exams than on vacation. Stress and negative emotions can accelerate the progression of HIV to AIDS and the speed of decline > reducing stress had positive effects. Stress does not create cancer cells, but can weaken our ability to fight cancer
Stress and heart disease
Coronary heart disease is the leading cause of death in Australia > significant influence of psychological states including stress, anger, pessimism and depression. May also occur via maladaptive coping behaviours
Occupational stress
Demands are associated with high levels of strain > demands can be offset by perception that one has control over aspects of the work of commensurate rewards
Managing stress
Relaxation programs were used to help Type A heart attack survivors reduce their risk of future heart attacks > lifestyle change to slow down, relax pace, smile, laugh, admit mistakes, find enjoyment (repeat heart attack was halved). First we appraise threat or challenge , then what we do is dependent on a number of factors
Personality: traits and types
1) Neuroticism and negative affectivity > linked to attention to internal states and increased somatic complaints
2) Type A > competitive, drive, inpatient, verbally aggressive and anger-prone people
3) Type B > refers to easy-going and relaxed people
Personality: pessimism vs optimism
1) Pessimist > tend to interpret stressors as uncontrollable, long-lasting and generalised to many life domains
2) Optimist > tend to report stressors as temporary, controllable and specific to one’s situation (optimism associated with less fatigue, fewer colds and even longer lifespan)
