Q

Why does insulin resistance increase fuel availability?

A

Because it increases blood sugar, so more fuel available for responses

Q

What happens in General Adaptation Syndrome?

A
  • Alarm induces fight or fight
    • Can’t maintain this state
      • Over days/weeks/months of stress, body is still performing at increased homeostatis levels, but body adapts, leading to resistance
  • Resistance can’t be maintained, leads to exhaustion
  • Exhaustion is a state of physiological/psychological exhaustion
    • Can get initial stress symptoms again
    • Chance of physiological damage and death

Q

What is the provlem with the stress response?

A

Stress response is adapted for survival advantage, as hunter-gatherers are more likely to be exposed to acute stressores, however modern life has a change in sorts of stressors

25
How can individual differences and context affect stress?
An individual may have different things that make something more or less stressful
26
Who proposed the transitional model of stress?
Lazarus and Folkman, 1984
27
How does the transitional model of stress define stress?
As the perception of interaction with individual person and what's going on around them
28
What does a person do in the transitonal model of stress?
* Demands * Resources * Constantly appraises this
29
What can demands be?
* Life events * Daily hassles * Chronic stressors
30
Give two examples of life events that could cause stress
* Illness * Bereavement
31
Give two examples of daily hassles that could cause stress?
* Losing keys * Missing bus
32
What resources may a person have?
* Personality * Social support * Coping skills
33
How may a person have developed coping skills?
They may have experienced stressor before, and so know strategies
34
According to the transitional model of stress, when does a person experience a stress response?
If percieved demands \> resources
35
What is meant by appraisal?
The way we think about things
36
What are the stages of appraisal?
* Primary appraisal * Secondary appraisal * Reappraisal
37
What questions may be asked in primary appraisal?
* Is the event a threat? * How bad could it be?
38
What questions are asked in secondary appraisal?
Do I have resources or skills to cope?
39
What happens in reappraisal?
Reconsider the situation once have tried to cope with it
40
What is the result of reappraisal?
May decide it's more or less stressful than before, moderating the stress response
41
What factors influence stress on individuals?
* Control over situation * Social support
42
How does control of the situation affect the stress response?
Often stressful things feel out of control
43
What study showed the effect of control over the situation on stress?
Whitehall 2 studies
44
What did the Whitehall 2 study find?
Looked at people in the Civil Service, found that males in jobs with low control were 50% more likely to develop stress related illnesses than those not
45
What effect does social support have on stress?
* Buffer against stress * Protects against experiencing * Helps cope when do experience
46
What showed the effects of social support on stress?
A systemic review, *which showed that lack of social support had the same effects as obesity and alcohol*
47
What effects does stress have on health?
* Physical damage, primarily to cardiovascular system * Affects immune function * Implication of stress in cancer, AIDS, herpes * Linked to unhealthy behaviours * Can lead to mental issues
48
What affect does acute stress have on the CVS?
Increases the risk of CVS events, particularly heart attacks
49
Why does acute stress increase the risk of heart attacks?
Because of the increases in mechanical stress on the heart
50
What % of sudden cardiac deaths are due to acute stressors?
20-40%
51
Other than CVS conditions, what is stress implicated in?
* Type 2 diabetes * Immune response implicated
52
Why is stress implicated in type 2 diabetes?
Due to the liberation of glucose
53
Give an example of a result of the immune response being implicated in stress?
Increases in common cold incidence
54
What effect do short/medium term stressors have on the immune system?
Cause an increase in the immune system functioning
55
Why do short/medium term stressors lead to an increase in immune system functioning?
Body gets ready to repair damage and resist infection
56
How does the body get ready to resist infection in short/medium term stress?
* Increase in cell mediated immunity with increases in lymphocyte numbers * Gets ready to fight off pathogens with antibodies and B cells
57
What effect do long term stressors have on immune function?
They decrease immune function
58
Why do long term stressors decrease immune function?
Causes inflammation and cortisol
59
What unhealthy behaviours is stress linked too?
* Alcohol * Junk food * Smoking
60
Why is stress related to unhealthy behaviours?
People develop maladaptive coping strategies, which makes the situation worse
61
Why can stress lead to mental health issues?
* Thinking more rigid and extreme under stress * Prone to cognitive distortions
62
What is meant by cognitive distortions?
Bad thinking habits
63
Who studied the effect of stress on mental health?
Beck, 1976

73
What is the problem with stress management?
It is a complex process, that requires complex and diverse management
74
What are the types of stress management?
* Cognitive strategies * Behavioural strategies * Emotional strategies * Physical strategies * Non-cognitive strategies
75
What are the cognitive strategies of stress management?
Trying to think about things differently
76
What techniques are used to try and think about things differently?
* Cognitive restructuring * Hypothesis testing
77
How is cognitive restructuring achieved?
CBT
78
Give a behavioural strategy of stess management
Skills training
79
When is skills training used?
For work related stress
80
What skills can be taught to deal with work related stress?
* Assertiveness * Time management
81
What are the emotional strategies of stress management?
