Huffman: PSYCHOLOGY IN ACTION, 6E
Health Psychology
• Health psychology examines the relationship
between psychological behavior and physical
health/illness
• Focus of health psychology is on
– Wellness
– Prevention of illness
• Many major causes of death are related to
behavior and lifestyle rather than to infections
– Smoking, drinking, risky sex are causes of death that
can be prevented

Smoking
• Cigarette smoking is the single most
preventable cause of death and disease in the
United States
• Smoking is a major risk factor for
–

–
–
Coronary heart disease
Cancer
Low birth weight, prenatal death
Fire deaths
• Secondhand smoke exposure is also a
significant health risk

Smoking Prevention
• Different factors may initiate and maintain
smoking
– Teens may start smoking as a means of rebellion or
because of peer pressure
– People may continue to smoke because nicotine is
addictive
• Nicotine releases transmitters such as acetylcholine,
dopamine, and norepinephrine
• These transmitters increase alertness and are rewarding
• Smoking relieves withdrawal symptoms
• Most smoking prevention programs focus on
psychosocial factors
– Minimize peer pressure to smoke

Binge Drinking
• Binge drinking refers to the consumption of
some number of alcoholic drinks in a single
session
– Male: 5 or more drinks
– Female: 4 or more drinks
• Approximately 5.1 million Americans could be
labeled as binge drinkers
• Binge drinking is a major problem on college
campuses
– 43% of college students are binge drinkers
– 20% of college students binge frequently

Binge Drinking in Colleges
• Student binge drinkers believe their drinking
levels are normal, when in fact their consumption
is above the norm
• Many students believe that binge drinking is
harmless
• Some students infer that binge drinking is fine
because the college does not tell them otherwise
• Binge drinking is often a key aspect of the Greek
experience of college life
• Alumni who binge drink give the impression that
such behavior is expected of students

Cross-Cultural Binge Drinking
• Mexico: binge drinking is an issue at fiestas
and can contribute to aggression
• Spain/South America: young binge drinking
males are more likely to exhibit aggression
• Denmark: wine drinkers are more likely to
show binging than are beer drinkers
• Russia: 44% of males qualify as bingers
• Japan: binge drinking is reduced in persons
who are unable to metabolize alcohol

Chronic Pain
• Pain is the most common symptom reported by
patients in visits to physicians
• Chronic pain involves continuous or recurrent pain
over a 6 month or longer period
• Chronic pain produces irritation, depression,
anxiety, and dependence on others
• Treatment of chronic pain can involve
– Exercise programs promote release of endorphins which
reduce pain perception
– Operant conditioning techniques reward “well behaviors”
– Biofeedback (electromyograph) can reduce muscle
tension
– Relaxation training reduces impact of pain

Stress
• Stress is a nonspecific response of the body to
any demand made on it
– Eustress: pleasant, desirable stress as in the stress
associated with exercise
– Distress: is unpleasant stress as in illness
• Stressors are stimuli that cause stress
– Stressors can be major (loss of a parent) or can be
minor (parking your car)
• Body eventually fails when subjected to chronic
stress

Life Changes as Stressors
• Life events can function as stressors
• When many life events occur in a short
period of time, enough stress can be
induced to alter health
• Holmes and Rahe developed the Social
Readjustment Rating scale (SRRS)
– Assesses the number of life changes in a
period of time and predicts the likelihood of
developing illness

Daily Stress
• Some stressors are chronic:
– Job-related (shift work, co-workers)
– Environmental stressors (aircraft noise)
• Hassles are small problems that accumulate to
induce major stress
– Time pressures to get things done
– Financial concerns
– Problems with family and coworkers
• Frustration is a negative emotional state
associated with a blocked goal
• Conflicts arise when choosing between 2
incompatible alternatives

Effects of Stress
• The sympathetic portion of the autonomic
nervous system is activated during stress
– Increased heart rate and blood pressure
– Release of adrenaline and cortisol
– These physiological changes use up energy
and can be sustained for only a period of time
– Prolonged stressor exposure leads to
exhaustion and death:

Stress and the Immune System
• Immune system functioning is impaired by
exposure to stress
– This immune response leaves a person susceptible
to disease
• Psychological events such as caring for a loved
one who has Alzheimer’s disease activates the
sympathetic system and impairs immune
response
– Hormone release during stress suppresses the
immune system and this increases the likelihood of
becoming ill

Huffman: PSYCHOLOGY IN ACTION, 6E
Stress and Serious Illness
• Cancer is affected by psychological factors
– Exposure to chemicals that cause cancer can be
modified by behavior
– Sleep deprivation can reduce immune function
– Personality traits can alter stress response
• Heart disease is associated with the buildup of
fats in blood vessels, stress increases this effect
– Type A personalities (ambitious, time urgent) are more
likely to suffer heart disease
– Reducing stress alters blood cholesterol so as to
reduce chance of blood vessel blockage

Huffman: PSYCHOLOGY IN ACTION, 6E
Personality and Stress
• Type A personality traits include time pressure,
anger, and hostility
– Behavior modification is used to encourage Type A
persons to slow down, follow a diet, to exercise, and to
avoid cynical hostility
• Hardiness is a personality type that is resistant to
stress
• Hardiness involves
– Commitment to personal goals
– Personal view of being in control
– Viewing change as a welcome challenge

Coping with Stress
• Stressors are pervasive in our lives
• Reducing stress can be accomplished by
either avoiding stressors or by reducing
our response to stressors
• Coping: managing stress in some
effective way
– Emotion-focused forms of coping change
how we view a situation (our reaction)
– Problem-focused forms of coping deal
directly with the stressor to eliminate it

Resources to Manage Stress
• Health and energy are key aspects to minimize
the damage produced by stress
• Positive beliefs are important for reducing stress
impact
• Social skills lead to social support
• Social support (network of friends, family)
reduces stress impact
• Material resources can help to minimize the
sources and types of stress
• Personal control allows people to buffer the
negative reactions to stress

• Relaxation during stress exposure
minimizes the impact of the exposure
• Exercise leads to physical fitness and
good health
– Reduces likelihood of illness
– Reduces negative impact of stress
