Stress: Impact on Health and Coping Mechanisms
Hans Selye’s General Adaptation Syndrome (GAS)
Hans Selye studied stress in rats and developed the General Adaptation Syndrome (GAS), a three-part theory of stress:
- Alarm: A stressor is recognized, triggering a physical reaction.
- Resistance: The body adapts to the stressor.
- Exhaustion: Long-term stress depletes the body’s resources.
The Immune System and Stress
The immune system comprises:
- Lymphocytes (white blood cells)
- Natural killer cells (NK cells)
Immune function is measured by:
- Counting white blood cells in a blood sample.
- Measuring NK cell activity after introducing cancer cells.
Stress significantly impacts health, leading to unhealthy behaviors and increased release of immune-hindering hormones.
Key Studies on Stress and Immunity:
- Bartrop: Demonstrated decreased immune function in response to grief.
- Stone: Showed a connection between life events and antibody levels.
- Visintainer: Found that stress increases the speed of cancer progression.
- Kiecolt-Glaser: Studied the stress of caring for a loved one.
Personality Factors in Stress
- Type A Personality: Competitive, achievement-oriented, time-urgent, and prone to anger and hostility.
- Type B Personality: Low levels of competitiveness, time urgency, and hostility.
- Phony Type B Personality: Appears as Type B but is internally tense, hostile, and troubled.
- Type D Personality: Suppresses emotions to gain approval from others.
Environmental Factors in Stress
- Approach-Approach Conflict: Choosing between two desirable options.
- Avoidance-Avoidance Conflict: Choosing between two undesirable options.
- Approach-Avoidance Conflict: A choice with both positive and negative aspects.
Psychoneuroimmunology and Hardiness
Psychoneuroimmunology is a branch of health psychology focusing on mind-body interactions.
Hardiness is the ability to cope with stress. Hardy individuals view stress as:
- A commitment rather than alienation.
- Controllable rather than powerless.
- A challenge rather than a threat.
Control and Stress Studies:
- Brady: Conducted a study with monkeys and stress (though without random selection).
- Weiss: Found that lack of control over outcomes increases stress in rats.
- Langer and Rodin: Studied stress and control in nursing homes.
Social Support and Stress
Social support (involvement with others) is crucial for managing stress:
- Individuals with non-supportive partners have longer recovery times.
- Strong social connections correlate with longer lifespans.
- Kraut: Found a negative correlation between internet connections and real-world social interaction.
- Liu and Yu: Showed that social support on Facebook is not related to well-being.
- Kross: Found that Facebook use can decrease happiness.
- Loneliness is linked to lower heart bypass survival rates and poorer sleep quality.
Coping with Stress
- Primary Appraisal: Assessing whether a situation is important.
- Secondary Appraisal: Determining how to address the situation (only reached if the primary appraisal is “yes”).
- Problem-Focused Coping: Directly addressing the stressor by solving the problem.
- Emotion-Focused Coping: Managing emotions and calming down.
Coping Techniques:
- Thought suppression: Ineffective.
- Meditation: A beneficial strategy.
- Aerobic exercise: Effective with commitment.
- Thinking positively and optimistically: Generally beneficial and can be learned.
Additional Concepts
- Pessimists: View failure as internal, global, and stable; success as external, temporary, and specific.
- Catharsis: Releasing anger through action or fantasy.
- Anger Diversion Techniques: Waiting, finding healthy distractions or support, and distancing oneself.
- Adaptation-Level Phenomenon: Judging experiences relative to past ones.
- Relative Deprivation: Perceiving oneself as worse off than others.

- Sociocultural Approach: Disorders occur within the context of society.
Gender and Disorders:
- Anxiety and depression are twice as likely in women.
- Substance abuse is twice as likely in men.
- Social anxiety is higher in men; women are taught to show emotion.
Thomas Szasz: Argued that mental illness is a myth (“problems in living”), which is incorrect.
