Review Stress Response • Life- stressor • Perceive as a threat • ALARM—Hippocampus (leads to an emotion) • SEAT OF EMOTIONS- Limbic System (…physical response) • RETICULAR ACTIVATING SYSTEM– (mind-body link) • SUPERVISOR- Hypothalamus (endocrine and autonomic) • Endocrine—Hormones (cortisol and vasopressin) • Autonomic- Sympathetic =ON, Parasympathetic =OFF
Hot Reactors • People who react to stress with an all-out physiological reaction. • This type of person tends to: • Become angry easily • Be anxious or depressed • Urinate frequently • Nausea and vomiting • Experience gastrointestinal problems
Psychosomatic Disease • Not “all in the mind” involves both mind and the body. • Psychosomatic disease may be: • Psychogenic • Somatogenic • At least 75%, if not more, of doctor visits are believed to have a stress component
Psychogenic-A physical disease caused by emotional stress without a microorganism involved. • The mind changes the body’s physiology so that body part breaks down. • Ulcers • Asthma • Somatogenic-A disease that results from the mind increasing the body’s susceptibility to: • Disease causing organisms (germs) • Natural degenerative processes • Cancer • Arthritis
Stress and Immunology • Stress can decrease your white blood cell count which will lead to poor health. • Immunological system includes the following white blood cell groups which identify and destroy foreign substances: • Phagocytes-destroyers • Lymphocytes • T cells • B cells
Stress and Serum Cholesterol • Significantly increases during stress. • Accumulates on the walls of your blood vessels blocking the flow of oxygenated blood to the heart and brain. • Studies show that one’s perception of a stressful situation can increase serum cholesterol levels. • Final Exams • Tax Accountants (April 15th)
Hypertension (High Blood Pressure) • Excessive pressure of blood against the walls of arteries • Ruptured arteries to the heart can result in a Myocardial Infarction (Heart Attack) • Ruptured arteries to the brain can cause a cerebral hemorrhage (Stroke) • 41% of Americans age 20-74 are Hypertensive • 16% of Americans age 20-24 are Hypertensive • Most don’t know it because it occurs without S/S.
Hypertension: High blood pressure • 20% of America has hypertension • Systolic-force against the arterial walls when the heart contracts and blood is pumped out. • Diastolic-force against the arterial walls when the heart is relaxed. • Normal: 120/80 • High: 140/90
Hypertension: Causes 90% Speculation- essential hypertension 10% Known • High sodium intake • Kidney disease • Cushing's syndrome • Oral contraceptives • Narrow heart/blood vessels • Smoking • Sedentariness • Obesity • Stress • Personality traits
Hypertension: Personality Traits • Upset by criticism • Upset by imperfection • Pent up anger, bitterness • Low self-confidence
Migraine Headaches • Constriction and dilation of the carotid arteries on one side of the head. • Prodrome- “preattack” or constriction phase of a migraine headache.
Coronary Heart Disease • Heart attacks kill more Americans than any other single cause of death. (Myocardial Infarction) • Major risk factors associated with CHD: • High serum cholesterol • Hypertension • Smoking • Obesity • Stress and a Type A behavior linked to CHD • Aggressive • Competitive • Time urgent • Multitasking
Coronary Heart Disease • Other Risks • Genetics • Sedentariness • High fat intake • Personality traits: • anger / hostile / resentful / bitter • Occupation: • the more stressful the job, the more prevalent is heart disease • Day of the week • Monday vs. Friday
Prevention of CHD • Reduce Fat Intake • Move Daily • Stop Smoking • Life style (Stress Management) • “Heart Transplant” • Forgive others • Forgive yourself • “Mend fences” in relationships
Life may begin at forty, but heart disease can begin at four.

If four jumbo jets crashed every day of the year in America, how anxious would you be to get on a plane?
That’s how many people die of cancer every day in America…it’s the second leading cause of death, behind heart disease. (1500 people)
Cancer • Definition: Unbridled multiplication of cells that leads to tumors, organ damage, and eventual death. • Metastisis: 4-part cycle of malignant tumor • Shed • Spread • Colonize • Grow
Cancer • The marvel of your immune system is its ability to distinguish between what’s ‘you’ and belongs from what’s ‘new’ and doesn’t belong. • Antigen • Any ‘new’ substance that triggers your immune response • Cancer Fighters • Interpheron, Interlucken2, Lymphotoxin, T-Lymphocytes
Cancer Chronic stress may disable the immune system in some people with some types of tumors (Not stating stress causes cancer!)
Seven Danger Signs of Cancer • Sores that don’t heal • Lump or thickening • Unusual bleeding / discharge • Persistent cough / hoarseness • Persistent indigestion • Change in wart or mole • Change in normal bowel / bladder habits
Characteristics of people prone to cancer • Inability to forgive • Use of self-pity • Difficulty developing / maintaining personal relationships • Poor self-image
