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.
Stress Appraisal
• Stress arises less from the event itself
than from how we appraise it. (Lazarus,
1998)
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
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.
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
General Adaptation Syndrome
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
– May be partly due to oxytocin
• Men are more likely to withdraw, self-medicate,
or become aggressive.
Stress Effects and Health
• Everything that is psychological is also
biological.
• Psychoneuroimmunology – a relatively new
field that studies how psychological, neural, and
endocrine processes combine to affect our
immune system and health
• Immune response includes two types of
lymphocytes (white blood cells),
macrophages, and natural killer (NK) cells.
• Age, nutrition, genetics, body temperature, and
stress all influence your immune response.
The Immune Response
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 self-attacking
diseases like lupus and MS.
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
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.
Stress and Cancer
• Stress does not create cancer cells, but:
• Stress may weaken a person’s ability to
fight off cancer.
– Studies are inconclusive
– There is danger in hyping reports on attitudes
and cancer
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.
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
– Zero were “pure” Type Bs
– Major problem for type A is negative
emotions, especially anger
Is Stress All Bad?
Stress motivates us, invigorates our lives,
makes our life challenging and productive.
The stress effect on our disease
resistance is the price we pay for the
benefits of stress.
Stress and Health:
The Stress Effect
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.
• How does this work? Possibilities:
– biological effects on arteries
– unhealthy depressive lifestyle choices.
Human Flourishing
• Coping With Stress
• Personal Control
Study: the single trait
shared by 169 people
over 100 was the ability to
manage stress well
Coping With Stress
• Problem-focused coping – addressing stress
directly by changing the stressor or the ways we
interact with it
– E.g., talk it out with the person we are fighting with
• Emotion-focused coping – attempting to
reduce stress by avoiding or ignoring a stressor
and attending to emotional needs related to our
stress reaction
– can be healthy we feel we cannot change the stressor
– can be maladaptive when we distract ourselves from
addressing a problem that could be solved.
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.
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
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.
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
“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
Self Control
Self Control: The ability to control
impulses and delay gratification
• Self-control is like a muscle:
Temporarily weakens after use, regains energy with
rest, and grows stronger with exercise
• Self-discipline in one area may strengthen
self-control in general and lead to a less
stressed life
Is the Glass Half Full?
• Optimism is the anticipation
of positive outcomes
• Pessimism is the anticipation
of negative outcomes
• Optimists tend to have better
health, and may live longer
• Success requires enough
optimism to provide hope, and
enough pessimism to keep us
on our toes
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
travel quickly among networks of
friends.
Finding Meaning
• Those with a strong sense of meaning for
a purpose for which to live, strong values,
and a sense of self-worth.
• Those who find meaning in a tragic event
have fewer adverse health effects and
lower rates of depression.
Managing Stress Effects
• Sometimes we cannot avoid experiencing
stress.
• What can we do to manage it?
– Aerobic exercise
– Relaxation
– Meditation
– Spirituality
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
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
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.
• Meditation enhances activity in the left frontal
lobe, associated with positive emotions. It also
improves immune functioning.
Spirituality
• The faith factor: Religiously active people
tend to live longer
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.
• These factors correlate with participation in religious
activities, not necessarily with strength of belief.
What Accounts for the Faith Factor?
