Stress, Lifestyle, Health Flashcards
Stress
•A process whereby an individual perceives and responds to events that he appraises as overwhelming or threatening to his well-being
Primary Appraisal
•Involves judgement about the degree of potential harm or threat to well-being that a stressor might entail
Secondary Appraisal
•Judgement of the options available to cope with stressor, as well as perceptions of how effective such options will be
Benefits of Stress
•Motivate us to do things in our best interests and perform to the best of our ability at work
Eustress
- Refers to a good kind of stress associated with positive feelings, optimal health, and performance
- Moderate amount of stress can be beneficial in challenging situations
Distress
- Refers to when stress exceeds the optimal level
* Individuals feel burned out; fatigued, exhausted, and their performance begins to decline
Health Psychology
•A subfield of psychology devoted to understanding the importance of psychological influences on health, illness, and how people respond when they become ill
Various Responses due to Stress
- Physiological (e.g., accelerated heart rate, headaches, or gastrointestinal problems)
- Cognitive (e.g., difficulty concentrating or making decisions)
- Behavioral (e.g, drinking alcohol, smoking, or taking actions directed at eliminating the cause of the stress)
Cannon and the Fight-or-Flight Response
- According to Cannon, this response is a built-in mechanism that assists in maintaining homeostasis
- Occurs when a person experience a very strong emotions, especially those associated with a perceived threat
- The body is rapidly aroused by activation of both sympathetic nervous system and the endocrine system – prepares the person to either fight or flee from a perceived threat
Body Response of Fight-or-Flight
- Pupils dilate
- Heart rate increases
- Muscles tense and may tremble
- Respiration quickens; bronchial tubes dilate
- Perspiration begins
Selye and the General Adaption Syndrome
•Selye engaged in research involving sex hormones in rats
•Although he was unable to find an answer for what he was initially
researching, he incidentally discovered that when exposed to prolonged negative stimulation (stressors) – the rats
showed signs of adrenal enlargement, thymus and lymph node shrinkage, and stomach ulceration
•General Adaption Syndrome – the body’s non-specific physiological response to stress
Three Stages of General Adaption Syndrome
- Alarm Reaction – describes the body’s immediate reaction upon facing a threatening situation or emergency; body alarms you with a cascade of physiological reactions that provide you with the energy to manage the situation
- Stage of Resistance – initial shock of alarm reaction has worn off and the body has adapted to the stressor; body remains on alert and is prepared to respond, but with less intensity
- Stage of Exhaustion – no longer able to adapt to the stressor: body’s ability to resist becomes depleted as physical wear takes its toll on the body’s tissues and organs
Hypothalamic-pituitary-adrenal (HPA) axis
•Set of structures found in both the limbic system (hypothalamus) and the endocrine system (pituitary gland and adrenal glands) that regulate many of the
body’s physiological reactions to stress through the release of hormones
Adrenocorticotropic Hormone (ACTH)
- Regulate levels of the steroid hormone cortisol, which released from the adrenal gland
- Produced in the anterior, or front, pituitary gland in the brain
Cortisol
- Commonly known as stress hormone
* Helps provide a boost of energy when we first encounter a stressor, preparing us to run away or fight
What happens if Cortisol Levels remains High?
- Weakens immune system
- Contributes to the development of psychological disorders
- Contributes to the development and progression of a variety of physical illnesses, and diseases
Post-traumatic Stress Disorder (PTSD)
•A chronic stress reaction characterized by experiences and behaviors that may include intrusive and painful memories of the stressor event, jumpiness, persistent negative emotional states, detachment from others, angry outbursts, and avoidance of reminders of the event
Social Re-adjustment Rating Scale (SRRS)
- Popular scale designed to measure stress
- Consists of 43 potentially stressful events, each of which has a numerical value quantifying how much re-adjustment is associated with the event
Daily Hassles
•Refers to the minor irritations and annoyances that are part of our everyday lives – can build on one another and leave us just as stressed as life change events
Job Strain
•Refers to a work situation that combines excessive job demands and workload with little discretion in the decision making or job control (e.g., inability to decide when to take a break)
Job Burnout
•A general sense of emotional exhaustion and cynicism in relation to one’s job
Three Dimensions of Job Burnout
•Exhaustion – a sense that one’s emotional resources are drained or that one is at the end of her rope and has
nothing more to give at a psychological level
•Depersonalization – a sense of emotional detachment between the worker and the recipients of his services, often resulting
in callous, cynical, or indifferent attitudes toward these individuals
•Diminished personal accomplishment – tendency to evaluate one’s work negatively
Psychophysiological Disorders
•Refers to physical disorders or diseases whose symptoms are brought about or worsened by stress and emotional factors
Types of Psychophysiological Disorders
- Cardiovascular – hypertension, coronary heart disease
- Gastrointestinal – irritable bowel syndrome
- Respiratory – asthma, allergy
- Musculoskeletal – low back pain, tension headaches
- Skin – acne, eczema, psoriasis
