Stress: Some Basic Concepts
Stress is defined as the process by which
we perceive and respond to certain events
called stressors that we appraise as
threatening or challenging.
4
Stress Appraisal
• Stress arises less from the event itself
than from how we appraise it. (Lazarus,
1998)
5
Three Main Types of Stressors
• Catastrophes
– Unpredictable large-scale events
• Significant life changes
– Leaving home, getting married, changing jobs, death
of a loved one, etc.
– One is more disease-prone following such changes
• Daily hassles
– More significant hassles include low wages, poor
health, neighborhood problems
– Can lead to high blood pressure and other health
problems
6
Stress Reactions
• Stress response involves mind and body.
• Walter Cannon (1929) found extreme cold, lack
of oxygen, and emotion arousal all trigger
release of stress hormones from adrenal glands.
• Sympathetic nervous system engages fight-orflight response, which mobilizes energy and
activity for attacking or escaping a threat.
7
8
Stress Reactions
• Hans Selye (1936) studied
animals’ reactions to stressors.
• Discovered that the body has a
common pattern of responding to
a variety of stressors, which he
called the General Adaptation
Syndrome (GAS):
1. Alarm
2. Resistance
3. Exhaustion
9
General Adaptation Syndrome
10
Other Ways of Dealing with Stress
• Withdraw, pull back, and conserve energy
• Some may become paralyzed with fear in the
face of disaster.
• Tend-and-befriend – under stress, some
people (especially women) often both provide
support to and seek support from others
– Men are more likely to withdraw, self-medicate, or
become aggressive.
11
Stress Effects and Health
• Psychoneuroimmunology – a field that studies
how psychological, neural, and endocrine
processes affect our immune system and health
• Immune response includes two types of
lymphocytes (white blood cells)
• macrophages, and natural killer (NK) cells.
12
The Immune Response
13
Immune System Errors
• Responding too strongly: the immune
system may attack the body’s own tissues
– Arthritis, allergies
• Underreaction: May allow dormant virus to
erupt or cancer cells to multiply
• Women have stronger immune systems.
– This makes them less likely to get infections,
but more susceptible to diseases like lupus
and MS.
14
Stress Effects and Health
• The immune system
becomes less active
when the body is flooded
with stress hormones.
– Wounds heal more slowly
– More vulnerable to colds
15
Stress and AIDS
• People with AIDS already have a
damaged immune system.
• Stress and negative emotions speed the
transition from HIV to AIDS.
• Stress leads to a faster decline in those
with AIDS.
• Reducing stress can help control AIDS.
16
Stress and Cancer
• Stress does not create cancer cells, but:
– Stress may weaken a person’s ability to fight
off cancer.
17
Stress and Heart Disease
• Stress is closely linked with coronary heart
disease – the clogging of the vessels that
nourish the heart.
– Coronary heart disease is the leading cause of death
in North America.
• Study of tax accountants – risk of heart disease
peaks right before April 15.
18
Stress and Health: The Role of
Personality
• Nine-year study of 3000+ men,
aged 35-39. At start, they were
interviewed and categorized:
– Type A: competitive, hard-driving,
impatient, verbally aggressive, angerprone, combat-ready
– Type B: easygoing and relaxed
• At end of study, 257 heart attacks
– 69% were Type A
19
Is Stress All Bad?
Stress motivates us, invigorates our lives,
makes our life challenging and productive.
But stress makes us less resistant to
disease.
20
Stress and Health:
The Stress Effect
21
Depression: More on Mental Health
Affecting the Heart
• Study: Depression increases risk of
worsening heart problems by 400%
• Study: Depression increases risk of death
as much as smoking does.
22
Human Flourishing
• Coping With Stress
Study: the single trait shared by 169 people
over 100 was the ability to manage stress well
23
Coping With Stress
• Problem-focused coping
• Emotion-focused coping
24
Personal Control
• Personal control is our sense of seeing
ourselves in control of our environment.
• Psychologists study this in two ways:
– They correlate peoples fellings of control with
behaviors and achievements.
– They experiment, by raising or lowering
people’s sense of control and noting the
effects.
25
Control, Morale, and Health
• Seligman (1975) strapped dogs in a
harness and gave them electric shocks
• When later placed in another situation
where they could escape the punishment
by simply leaping over a hurdle, the dogs
cowered and did not move
• Other dogs that were able to escape the
first shocks did not act this way
26
Control, Morale, and Health
• Learned helplessness is the term for the
hopelessness and passive resignation an animal
or human learns when unable to avoid repeated
aversive events.
• Perceived loss of control predicts health
problems.
• Ability to control one’s environment leads to
greater happiness and productivity.
27
Who’s at the Controls?
• Is your life out of your control? Is the world run
by a few powerful people?
• Do you control your own fate? Is being a
success a matter of hard work?
• External locus of control: the perception that
chance or outside forces beyond personal
control determine our fate
• Internal locus of control: the perception that
we control our own fate
28
“Internals” and “Externals”
• Internals assume an internal locus of
control.
– believe they control their own destiny
– achieve more in school and work, enjoy
better health, and feel less depressed than
there counterparts:
• Externals assume an external locus of
control.
– view that chance or outside forces control
their fate
29
Self Control
Self Control: The ability to control
impulses and delay gratification
• Self-control is like a muscle:
– it grows stronger with exercise
• Self-discipline in one area may strengthen
self-control in general and lead to a less
stressed life
30
Is the Glass Half Full?
•
Optimism is the anticipation of positive
outcomes
• Pessimism is the anticipation of negative
outcomes
1. Optimists tend to have better health, and may
live longer
2. Success requires optimism but enough
pessimism to us alert
31
Social Support
• Feeling liked and encouraged by friends and
family promotes both happiness and health.
• Social support can calm the cardiovascular
system and foster stronger immune functioning.
• Both good and bad habits can quickly migrate
to ones friends.
32
Finding Meaning
•
•
Doing a Google search of ‘the meaning
of life’ resulted 6,720,000 hits
Those with a strong sense of meaning
1. See a purpose for their lives and have strong
values, and a sense of self-worth.
2. Those who find meaning in a tragic event have
fewer adverse health effects and lower rates of
depression.
33
Managing Stress Effects
• Sometimes we cannot avoid experiencing
stress.
• What can we do to manage it?
– Aerobic exercise
– Relaxation
– Meditation
– Spirituality
34
Aerobic Exercise
• Aerobic exercise,
sustained activity that
increases heart and
lung fitness, may
reduce stress,
depression and anxiety
• Study: mildly depressed
women improved more
with exercise than with
relaxation exercises
35
Relaxation: Lifestyle Modification
• Study with Type A heart attack survivors: a control group was
given advice about medications, diet, and exercise.
• A second group was given this advice PLUS guidance in
modifying their lifestyle–
Walking, laughing, eating slowly
36
Can we tell which part of the intervention made the difference?
Relaxation: Meditation
• Relaxation procedures can provide relief from
headaches, high blood pressure, anxiety, and
insomnia.
• The relaxation response:
– Sit quietly in a comfortable position. Close your eyes.
Relax your musicles, starting with your feet and
moving slowly upward. Breathe slowly, and on the
exhale focus on a word, phrase or prayer. Repeat for
10-20 minutes.
37
Spirituality
• The faith factor: Religiously active people
tend to live longer
38
Possible explanations for the
Faith Factor?
• Religiously active people tend to have healthier lifestyles.
– less alcohol, dietary fat, and smoking
• Belonging to a faith community is to have access to a
support network.
– Religion encourages marriage, another predictor of health
and longevity
• Religion promotes positive emotion, optimism, a stable
world-view, and relaxed meditation.
39
