The Nature of Stress Flashcards
“Lifestyle diseases, or diseases caused by stress
heart disease, cancer, lung ailments, accidents, cirrhosis, and suicide
Definition of lifestyle diseases
For the most part, LD are preventable or correctable by altering the habits and behaviors that contribute to their etiology
Most notorious lifestyle disease
Coronary heart disease (CHD)
Holistic medicine
A healing approach that honors the integration, balance, and harmony of mind, body, spirit, and emotions to promote inner peace. Every technique used in stress management is considered to support the concept of holistic medicine.
Walter Cannon
20th century Harvard physiologist who coined the term “fight or flight”
Fight or flight response
A term coined by Walter Cannon; the instinctive physiological responses preparing the body, when confronted with a threat, to either fight or flee; an evolutionary survival dynamic
Stress reaction
The body’s initial (central nervous system) reaction to a perceived threat
Freeze response
Part of the stress response, where the individual neither fights nor flees but freezes like a deer caught in the headlights, paralyzed as if the person has forgotten to run.
Fight response
Triggered by anger or aggression; usually employed to defend territorial boundaries or attack aggressors equal to or smaller in size; requires physiological preparations that recruit power and strength for a short duration
Flight response
Induced by fear; designed to fuel the body to endure prolonged movement such as running away from lions and bears; includes not only fleeing, but also hiding or withdrawal
Homeostasis
A physiological state of complete calmness or rest; markers include resting heart rate, blood pressure, and ventilation
Stress response
The release of epinephrine and norepinephrine to prepare various organs and tissues for fight or flight
Physiological mechanisms to the fight-or-flight response
- Increased heart rate to pump oxygenated blood to working muscles, 2. Increased blood pressure to deliver blood to working muscles, 3. Increased ventilation to supply working muscles with oxygen for energy metabolism, 4. Vasodilation of arteries to the body’s periphery (arms & legs) with the greatest muscle mass, 5. Increased serum glucose for metabolic processes during muscle contractions, 6. Increased free fatty acid mobilization as an energy source for prolonged activity, 7. Increased blood coagulation and decreased clotting time in the event of bleeding, 8. Increased muscular strength, 9. Decreased gastric movement and abdominal blood flow to allow blood to go to working muscles, 10. Increased perspiration to cool body-core temperature
Tend & Befriend
A theory presented by Shelley Taylor that states that women who experience stress don’t necessarily run or fight, but rather turn to friends to cope with unpleasant events and circumstances
Co-rumination
Stress-based conversation between women as a means of coping by finding support among friends
Eustress
Good stress; any stressor that motivates an individual toward an optimal level of performance or health
Neustress
Any kind of information or sensory stimulus that is perceived as unimportant or inconsequential
Distress
The unfavorable or negative interpretation of an event (real or imagined) to be threatening that promotes continued feelings of fear or anger; more commonly known simply as stress
Acute stress
Stress that is intense in nature but short in duration
Chronic stress
Stress that is not as intense as acute stress but that lingers for a prolonger period of time (e.g. financial problems)
Yerkes-Dodson principle
The theory that some stress (eustress) is necessary for health and performance but that beyond an optimal amount both will deteriorate as stress increases
Stressor
Any real or imagined situation, circumstance, or stimulus that is perceived to be a threat
