Stress and Health Behavioral medicine: an interdisciplinary
field that integrates behavioral and medicinal knowledge and applies that knowledge to health and disease
Health psychology: a subfield of psychology that provides psychology's contribution to behavioral medicine

Stress and Stressors Stress: The process by which we perceive
and respond to certain events, called stressors, that we appraise as threatening or challenging.
Stress is how we cope with threats and challenges throughout life.
Stressors are the causes of stress, stress reactions are your physical and emotional responses to stress, and stress is the way you relate to your environment.

Pros of Stress Momentary stress can mobilize the
immune system for fending off infections and healing wounds
Arouses and motivates us to conquer issues
Conquering a stressful event leads to higher self esteem and a sense of purpose

Cons of Stress Severe stress can lead to a suppressed
immune system and progression of diseases
![Page 6: Chapter 14: Stress and Health](https://reader035.fdocuments.in/reader035/viewer/2022062520/568164da550346895dd72627/html5/thumbnails/6.jpg)
The Stress Response System
Walter Cannon Found that stress response is part of a unified mind-body system
Sympathetic nervous increases heart rate and respiration, diverts blood to the skeletal muscles, dulls pain, releases sugars and fat
Prepares for fight or flight
![Page 7: Chapter 14: Stress and Health](https://reader035.fdocuments.in/reader035/viewer/2022062520/568164da550346895dd72627/html5/thumbnails/7.jpg)
GAS General adaption syndrome: Selye’s
concept of the body’s adaptive response to stress in three stages
Stage one: Alarm reaction Stage two: Resistance to stress Stage three: Exhaustion – vulnerability to
disease
![Page 8: Chapter 14: Stress and Health](https://reader035.fdocuments.in/reader035/viewer/2022062520/568164da550346895dd72627/html5/thumbnails/8.jpg)
Stressful life events Catastrophes: unpredictable large scale
change, example: 9/11 Significant life changes: life transitions
and insecurities example: leaving home, death
of a loved one Daily hassles: everyday annoyances
example: school
![Page 9: Chapter 14: Stress and Health](https://reader035.fdocuments.in/reader035/viewer/2022062520/568164da550346895dd72627/html5/thumbnails/9.jpg)
Stress and the heart Large amounts of stress lead to elevated
blood pressure and increase the risk of coronary disease
Coronary disease: The clogging of the vessels that nourish the heart muscle; the leading cause of death in most developed countries
![Page 10: Chapter 14: Stress and Health](https://reader035.fdocuments.in/reader035/viewer/2022062520/568164da550346895dd72627/html5/thumbnails/10.jpg)
Personalities Type A: Friedman and Roseman’s term for
competitive, hard driving, impatient, verbally aggressive, and anger prone people. These people are more likely of heart diseaseexample: when your history IA is due in one day
Type B: Friedman and Roseman’s term for easygoing, relaxed peopleexample: when your history IA is due in two days

Stress and Susceptibility to Disease
Psycho Physiological Illnesses: “Mind-body” illnesses; any stress related physical illness
![Page 12: Chapter 14: Stress and Health](https://reader035.fdocuments.in/reader035/viewer/2022062520/568164da550346895dd72627/html5/thumbnails/12.jpg)
Stress and the Immune System The nervous and endocrine system have
an influence on the immune system
![Page 13: Chapter 14: Stress and Health](https://reader035.fdocuments.in/reader035/viewer/2022062520/568164da550346895dd72627/html5/thumbnails/13.jpg)
Lymphocytes Lymphocytes: The two types of white
blood cells that are part of the body’s immune system: B lymphocytes form in the bone marrow and release antibodies that fight bacterial infection; T lymphocytes form in the thymus and other lymphatic tissue and attack cancer cells, viruses and foreign substances.
B for bone, T for thymus
![Page 14: Chapter 14: Stress and Health](https://reader035.fdocuments.in/reader035/viewer/2022062520/568164da550346895dd72627/html5/thumbnails/14.jpg)
Immune System Errors Strong response: May attack the body’s
own tissue, causing arthritis or an allergic reaction
Weak response: May allow a dormant disease to erupt or multiply
![Page 15: Chapter 14: Stress and Health](https://reader035.fdocuments.in/reader035/viewer/2022062520/568164da550346895dd72627/html5/thumbnails/15.jpg)
Stress’s Affect on the Body Wounds heal slowly: Unstressed participants
wounds healed 40% faster More vulnerable to disease: Unstressed
participants were 20% more unlikely to catch a disease
Weakened immune system: Stressed participants showed a 15% below average immune antibody response and a 23% increase in stress hormones
Life shortening: A noticeable characteristic of people who have lived over 100 is their ability to handle stress
![Page 16: Chapter 14: Stress and Health](https://reader035.fdocuments.in/reader035/viewer/2022062520/568164da550346895dd72627/html5/thumbnails/16.jpg)
Stress and Aids Aids is the fourth largest cause of death Infected people with stressful life
circumstances exhibit greater disease suppression and a faster disease progression
![Page 17: Chapter 14: Stress and Health](https://reader035.fdocuments.in/reader035/viewer/2022062520/568164da550346895dd72627/html5/thumbnails/17.jpg)
Stress and Cancer Stress and negative emotion have been
linked to cancer’s rate of progression People with a history of stress were
reported 5.5 times more likely to get colon cancer
Stress doesn’t cause cancer but it weakens the body allowing it to progress
![Page 18: Chapter 14: Stress and Health](https://reader035.fdocuments.in/reader035/viewer/2022062520/568164da550346895dd72627/html5/thumbnails/18.jpg)
Conditioning the Immune System
Placebo effect on stress When you think something bad or
stressful will occur before it does you still exhibit the symptoms
![Page 19: Chapter 14: Stress and Health](https://reader035.fdocuments.in/reader035/viewer/2022062520/568164da550346895dd72627/html5/thumbnails/19.jpg)
Coping with stress Coping: alleviating stress using
emotional, cognitive, or behavioral methods
Problem focused coping: attempting to alleviate stress directly – by changing the stressor or the way we interact with that stressor
Emotion focused coping: attempting to alleviate stress by avoiding or ignoring a stressor and attending to emotional needs related to one’s stress reaction
![Page 20: Chapter 14: Stress and Health](https://reader035.fdocuments.in/reader035/viewer/2022062520/568164da550346895dd72627/html5/thumbnails/20.jpg)
Coping with stress (cont.) Stress correlates with heart disease,
lowered immunity and other bodily ailments
We as individuals need to learn to cope with stress by finding ways to alleviate it
![Page 21: Chapter 14: Stress and Health](https://reader035.fdocuments.in/reader035/viewer/2022062520/568164da550346895dd72627/html5/thumbnails/21.jpg)
Perceived control When we perceive a loss of control, we
become more likely to get ill health Perceiving a lack of control can lead to
cardiovascular disease and a shorter life span because of an outpouring level of stress hormones
![Page 22: Chapter 14: Stress and Health](https://reader035.fdocuments.in/reader035/viewer/2022062520/568164da550346895dd72627/html5/thumbnails/22.jpg)
Explanatory style An influence on coping with stress is
whether we are more optimistic or pessimistic
Optimist are more likely to be able to deal with stress because they feel they have more control
Pessimist are statistically more likely to be stress and are more often sick than optimist
![Page 23: Chapter 14: Stress and Health](https://reader035.fdocuments.in/reader035/viewer/2022062520/568164da550346895dd72627/html5/thumbnails/23.jpg)
Social support Social support is a large factor in stress Feeling liked, affirmed, and encouraged
by friends or family greatly reduces stress People with larger amounts of social
support have lower blood pressure
![Page 24: Chapter 14: Stress and Health](https://reader035.fdocuments.in/reader035/viewer/2022062520/568164da550346895dd72627/html5/thumbnails/24.jpg)

Biofeedback Biofeedback: system for electronically
recording, amplifying, and feeding back information regarding a subtle physiological state, such as blood pressure or muscle tension
![Page 26: Chapter 14: Stress and Health](https://reader035.fdocuments.in/reader035/viewer/2022062520/568164da550346895dd72627/html5/thumbnails/26.jpg)
Relaxation Can help alleviate headaches,
hypertension, anxiety, and insomnia

Meditattion Cardiologist Herbert Benson became
interested with meditative relaxation when he experienced that people that meditate could decrease their blood pressure, heart rate, and oxygen consumption

Obesity and weight control Our bodies store fat because it’s a fuel
reserve to help to continue when food is scarce
However in most of the world food is no longer scarce which has raised the obesity rate
