WEEK 6- Health Stress and Coping Flashcards
Health Psychology
Is a field that centres on the promotion and maintenance of health, ways of preventing illness, and understanding of the individual to the entire healthcare system. The work of health psychologists is part of the broader field of behavioral medicine, in which psychologists persue their health-related goals in cooperation with physicians, nurses, public health workers and other biomedical specialties.
Eustress
The “good “ form of stress that is associated withpositive feelings, optimal health and performance. Stress level must be low to moderate, at optimal level, performance has reached its peak.
Distress
Is when stress exceeds the optimal level, and it is no longer a positive force. It becomes excessive and debilitating. People who reach this level of stress feel burned out; they are fatigued, exhausted, and their performance and health begins to decline. Its the “bad” form of stress.
How chronic stress affect the brain?
By reducing his size, structure and functions.
Stress begins with a process called:
Hypothalamus Pituitary Adrenal Axis
Hypothalamus Pituitary Adrenal Axis
Is a series of interaction between the endocrine glands in the brain and kidney which controlls the body reaction to stress. When the brain detects a stress situation, the HPA activates realising a hormone called cortisol which primes your body for instanct action.
High levels levels of cortisol for a long period of time is bad for the brain, why?
Cortisol can cause the brain to shrink its size, too much of it involves in the loss of synaptic connection between neurons, and the shrinking of the prefrontal cortex which involves behavior like concentration, judgement and decision making and social interaction. It also leads to fewer new brain cells being made in the hippocampus.
Chronic stress involves
In not remebering things and not learning and can lead to depression and alzheimer.
Epigenetics
Is the study of heritable changes in gene expression (active versus inactive genes) that do not involve changes to the underlying DNA sequence.
Poor Health consists of:
Behavioral factors such as lack of exercise, inadequate diet, smoking, abuse of alcohols, and drugs.
Good Health consists in
Being optimistic, experiencing positive emotions, and behaviours such as adequate exercise and following medical advice.
_________ diseases affects more a person psychologically.
Chronic diseases like cancer and heart.
Life expectancy on average Australian is ____ on females and ____ males.
84; 79.
In Australia, the top cause of death is _________ on both males and women. And in New Zealand is___________ in females and _______________ in males.
Coronary heart disease.
Lung cancer; Ischemic heart disease.
Stress
Are internal processes that occur as people try to adjust to events and situations that they perceive as threatening or overwhelming, especially. Stress is an internal state. Another definition: (Selye) the nonspecific response of the body to any demand.
Stressors
Are the events and situations that stress creates and people must adjust.
What do stressors have in common?
They all disrupt or threaten to disrupt daily functioning and cause people to make adjustments. Stressors can be mild and temporary or severe and lasting.
External stimulis triggers ________.
Stress
Stress reactions
Are physical, psychological, emotional, cognitive and behavioral responses that occur in the face of stressors. In other words, stress involves transaction between people and their physical and psychological environments. When stress reactions are confronted by stressor, people may respond physically (with nausea and fatigue for example) and psychologically (with anxiety, lack of concentration or changes in eating habits).
Stress mediators
The transactions between people and their environments can be influenced by stress mediators. These mediators include such variables as the extent to which people can predict and control their stressors, how they interpret the threat involved, the amount of social support they perceive as available from family and friends, and their stress-coping skills. Stress mediators, however, can minimize or magnify a stressor’s impact and include factors such as perceptions of control or threat, social support and coping skills.
To deal with consequences of trauma, health psychologists do ______________ and _______________.
On spot counselling and follow up sessions.
The most adverse psychological stressors are
Events and situations that are perceived as unpleasant and threatening.
Psychological stressors involve:
Catastrophic events, life changes and strains, chronic problems and daily hassles.
Catastrophic events
Are sudden, unexpected, potentially life-threatening experiences or traumas, such as physical or sexual assault, military combat, natural disasters, terrorist attacks and accidents.
Life changes and strains include
Divorce, illness in the family, difficulties at work and other circumstances that create demands to which people must adjust.
Chronic problems
Those that continue over a long period of time. It comprises circumstances such as living in a high-crime neighborhood or under the threat of terrorism, having a serious illness, being unable to earn a decent living, being the victim of discrimination, and even enduring years of academic pressure.
Ways that chronic stress can sabotage the life of a person:
Are with acne, hair loss, sexual dysfunction, headaches, muscle tension, irritability and lack of concentration.
Daily hassles
Are irritations, pressures and annoyances that may not be significant stressors by themselves but whose cumulative effects can be significant.
How stressors are measured?
With Life change units (LCUs), Social Readjustment Rating Scale, SRRS and - Life Experiences Survey or LES.
Life change units (LCUs)
It measures by asking questions the amount of change and demand for adjustment associated with events such as divorcing, being fired, retiring, losing a loved one or becoming pregnant.
Social Readjustment Rating Scale, SRRS
People taking the SRRS receive a stress score equal to the sum of the LCUs for the events they have recently experienced.
Life Experiences Survey or LES.
Go beyond the SRRS to measure not just life events but also peoples perceptions, or cognitive appraisals, of how positive or negative the events were, how controllable they were, and how well they were able to cope. The LES also gives respondents the opportunity to write in and rate any stressors they have experienced that are not on the printed list. This personalized approach is particularly valuable for capturing the differing impact and meaning that experiences may have for men compared with woman and for individuals from various cultural or subcultural groups.
Physical stress responses.
Include rapid breathing, increased heartbeat, sweating and shakiness, decreases in digestive activity, release of glucose from the liver for energy. These reactions are part of a general pattern known as fight-flight reaction or syndrome.
General adaptation syndrome, GAS
Is a 3-stage pattern of responses triggered by the effort to adapt to any stressor found by Hans Selye/ He stated that physical reactions to stressors include an initial alarm reaction, followed by resistance and then exhaustion.
Initial Alarm reaction
Involves some version of the fight-or-flight syndrome. In the face of a mild stressor such as an overheated room, the reaction may simply involve changes in heart rate, respiration and perspiration that help the body regulate its temperature. Environmental demands (stressors) trigger a process in the brain in which the hypothalamus activates the sympathetic branch of the ANS, which stimulates the medulla (inner part) of the adrenal gland. The adrenal gland, in turn, secretes catecholamines (which mobilizes the body for action). The results are increased blood pressure, enhanced muscle tension, increased blood sugar, strokes, cholesterol in arteries, vessel obstruction, and hearburn (acid) and other physical changes that provide the energy needed to cope with acute stressos.
How does stressors activate the pituitary-adrenocortical system (HPA) how?
Through the HPA, the hypothalamus causes the pituitary gland in the brain to trigger the release of endorphins, the body’s natural painkillers. The HPA which involves the adrenocorticotropic hormone (ACTH) also stimulates the release of corticosteroids (hormones), which help resist stress but also tend to suppress the immune system . The overall effect of these stress systems is to generate emergency energy.
Catecholamines
Is secreted by the adrenal gland which mobilizes the body for action, especially cortisol, adrenaline and noradrenaline which circulate in the bloodstream, activating various organs, including the liver, kidneys, heart and lungs.
Resistance Stage
If stressors persist, the resistance stage of the GAS begins. Here, obvious signs of the initial alarm reaction fade as the body settles in to resist the stressor on a long-term basis. The drain on adaptive energy is slower during the resistance stage than it was during the alarm reaction, but the body is still working hard, physiologically, to cope.
Exhaustion Stage
It slowly but surely uses up the body’s reserves of adaptive energy. The organ systems involved in prolonged resistance to stressors eventually breaks down. In extreme cases, such as prolonged exposure to freezing temperatures, the result is death. More commonly, the exhaustion stage brings signs of physical wear and tear, especially in organ systems that were weak to begin with or that were heavily involved in the resistance process.
Diseases of adaptation
Illnesses that are caused or worsened by stressors (we see this on the exhaustion stage).
Psychological responses to stress.
Include emotional, behavioral and cognitive changes.
