Stress Affecting the Immune System Essay Example

Just Relax and be Healthy

Worrying over a test is normal for any student. However, tests are not the only things students have to worry over. Family matters, money problems, boyfriends or girlfriends, and even the death of a loved one can add stress to an individual. As things keep adding up and the stress level keeps rising, some students may find themselves getting sick. Before the 1970’s there was no reason to believe that stress and the immune system had anything to do with each other. This relationship which was thought to be “non-existent” would soon be found to be real and affecting millions of people. The subject became so real in the scientific world it was given its own name psychoneuroimmunology. This obnoxiously large word is just a way of stating there are connections between psychological process, the nervous system, and the body’s immune system (507). The field of psychoneuroimmunology put power behind every college student’s excuse of “getting sick from stress of classes”, however this excuse did not generate any less homework. It was not until a psychologist Robert Ader decided to work with an immunologist named Nicholas Cohen that the stress-sickness relationship became more than a notion. It was thought that immune system was completely separate from any other bodily systems, however “The central nervous system and the immune system are directly linked via sympathetic nervous system fibers, which influence the production of lymphocytes” (507). Plainly, the immune system is affected by the central nervous system which directly deals with stress. The central nervous system (CNS) deals with stress directly because the brain is located within the CNS. Lymphocytes are the white blood cells in the body that fight pathogens and anything that may harm the individual. If the regulation of white blood cells is not normal, then sickness may occur. Also, studies were conducted where individuals were

    Kiecolt and Glaser conducted an experiment to see the effects of stress on the immune system. This was achieved by taking blood samples of 75 medical students one month before and during their examination period. They then compared the two blood samples and found decreased leucocyte activity in the sample taken during high levels of stress (during their exams). This shows that stress reduces the activity of the immune system, making them more susceptible to becoming ill.…

    3 Who is Hans Selye? What is the General Adaptation Syndrome and what happens at each stage? What is the Hypothalamus-Pituitary-Adrenal (HPA) Axis? Hans Selye is a Canadian physician who ignited the field of modern-day stress research. His genius was to recognize a connection between the stress response of animals, including stomach ulcers and increases in the size of the adrenal gland, which produces stress hormones. General Adaptation Syndrome (GAS) stress response pattern proposed by Hans Selye that consists of 3 stages: alarm, resistance, and exhaustion. Alarm: excitation of the autonomic nervous system, the discharge of the stress hormone adrenaline, and physical symptoms of anxiety, Resistance: adapts to the stressor and finds ways to cope with it, Exhaustion: our resistance may ultimately break down, causing our levels of activation to bottom out. The results can range from damage to an organ system, to depression and anxiety, to a breakdown in the immune system. Hypothalamus-Pituitary-Adrenal (HPA): the hypothalamus (H) and the pituitary gland (P) orchestrate the adrenals glands (A) release of another stress hormone, cortisol, which floods a person’s energy, while their hippocampus retrieves terrifying images…

    During strenuous times, our body undergoes many physiological changes in order to aid our survival, and this is an inherited function (Canon’s ‘fight or flight’ theory). Stress in small doses, in fact is needed and useful to humans, however long term stress can take its toll on the body. The General Adaptation Syndrome (GAS) model was developed by Selye to explain the effects of exposure to stressor. The GAS model consists of these 3 stages; Alarm – when our HPAC and SAM pathways are activated, causing stress related hormones like adrenaline and cortisol to be releases into blood, which in turn, converts to glucose, giving the body a sudden surge of energy, allowing ‘fight or flight’ like behaviours, until the stressor is gone and the parasympathetic nervous pathway activates, allowing us to calm down. Resistance – When the stressor remains however the person appears unaffected on the outside, but internally the stress related effects are occurring, e.g. stress hormones still being released and a continued elevation in heart rate. The resistance stage can harm health, as the immune system is not as effective. However the body attempts to resist disease. Further stressors make this much harder. Exhaustion – stressor still persists (and would now be referred to as Chronic stress) and Selye claimed that the body’s defences can no longer cope with the demands that are made, resources are drained, causing a drastic fall in blood sugar levels, and our adrenal glands no longer function properly. However this is inaccurate, which is a criticism of the GAS model, as while the body is ‘exhausted’ in terms of full ability, it could still perform if immediate action and release of energy was needed. It is also believed that many of the long lasting effects of raised stress hormones is what causes stress related illnesses, rather than the body’s sources being depleted. The study lacks ecological…

    The immune system helps fight off attacks from ‘foreign invaders’, the immune system is a network of cells, tissues and organs that help fight off attacks from viruses, parasites and micro organisms that enter our bodies that can cause infections and other problems. The idea that all the cells in our bodies have codes ‘tattooed’ onto them that are unique to each of us help us understand what the immune system does clearer. Whenever micro organisms ect, enter our bodies and don’t have our individual codes on them the immune system seeks these out and destroys them our bodies remember these and will make the us immune to them if they ever enter our bodies again.…

    Also, immune responses were particularly weak in those who reported experiencing stressful life events, psychiatric symptoms such as depression or anxiety, and loneliness. It can be concluded that stressful experiences such as exams reduce the effectiveness of our immune system. Therefore it could be said that periods of stress mean that you are more likely to be ill.…

    The immune system is made up of many interdependent cell categories such as cells, proteins, tissues, and organs that work together to protect the body. Several of these cell categories partake in a particular function. “The cells of the immune system can engulf bacteria, kill parasites or tumor cells, or kill viral-infected cells (The Immune System and Primary Immunodeficiency, n.d.)”. The immune system is a great teamwork among cells and proteins that work together to deliver defend against infection. The cells and proteins are not just one organ like the liver and the heart. The immune system is spread throughout the body to deliver a quick reaction to infection in the body. Cells are in our bloodstream and that’s how they travel throughout the body. The immune system is made of many different organs to protect the body.…

    Researchers have historically approached the study of stress from two perspectives: 1) a physiological account of the stress response, which consists of tracking the stress hormone cortisol and its effects on metabolism, immune function, and neural processes; and 2) a psychological/cognitive focus on how the perception and experience of a stressor influences the stress response. These approaches align with the nature vs. nurture debate, pitting nature, represented by the biology of cortisol responses, against nurture, in the form of external experience influencing cognitive processing. Academic researchers typically study stress by adopting one of these…

    Slavich, who wrote an article about stress and health, tells us that in a discovery it has been found that “stress can upregulate components of the immune system involved in inflammation.” Through this discovery, the occurrences of people getting sick from stress is now more credible. There once was a time in high school that my teacher achieved the highest level of annoyance from other classmates and decided that it was enough. Fed up with the students, she decided to make life a living hell by giving homework that towered over the Himalayas! Being the student that I was, I tried to keep up with the work that she had given. However, stress and anxiety kicked in and I could not think about anything, feeling brain dead and later becoming terribly sick I had to take a break. However, “not everyone who experiences stress gets sick” (Slavich). Researchers went to work once again trying to find other reasons on to why people got sick coming upon the discovery that “stressors involving social evaluation and rejection, which can induce experiences of “social pain,” activate some of the same brain regions that are engaged by physical pain“ (Slavich). As a high schooler, I always wondered why my brother Abraham was an oddball because he managed to never get sick through all his stresses of high school and college. Slavich’s research went on to make the conclusion that “one emerging idea is that individuals who are more neurally sensitive to social stressors may mount greater inflammatory responses to social stress.” This conclusion cleared many ideas onto why my brother did not get sick. He was the golden child of the family, meanwhile, my siblings and I tried to live up to his deeds to please our…

    - Neurological System- hormones and neurotransmitters inhibit- short term memory, concentration, inhibition, and rational thoughts. Interferes with ability to handle difficult social or intellectual tasks and behaviors. Hormones and neurotransmitters inhibit long term memory of response to the stress experienced. - Cardiovascular system- heart rate and blood pressure increase, breathing becomes rapid. Blood flow increases. Adrenaline acts on B1 receptors on heart, combing to increase blood output. Alpha receptors found in the blood vessel walls combine with adrenaline to effectively stimulate the blood vessels- better distribution. - Respitory System- increased respitory rate. - Immune System- defense weakens, the cells such as WBC are positioned in places where body thinks there is going to be an infection. Cortisol suppresses the immune system resulting in increased suseptability of infections. - Muscular System- contraction of muscles - Skeletal System - Endocrine System- secretion of hormones - Nervous System- CNS PNS • Describe what happens to specific organs during the stress response.
