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.…
There is proven to be correlation between stress & illness. Stress can cause problems with the circulatory system, problems such as high blood pressure, coronary heart disease caused by atherosclerosis and stroke.…
Stress has been widely identified to be linked with illness, which has therefore attracted researchers to investigate the relationship between the immune system and stress. Cohen et al for instance conducted a study where 369 participants were asked to complete a questionnaire which measured their Psychological Stress Index, consisting of a scale measuring their own perception of their stress levels, stressful life events in the previous years and negative emotions. The P’s were then given a nasal spray containing a respiratory virus and placed in quarantine, in order to test whether they would develop a cold. The results found that 82% of P’s developed a cold, but more importantly that people with high stress levels in the PSI were more susceptible to developing the clinical cold. In effect what Cohen concluded from this data is that stressful experiences and emotions can cause immunosuppression.…
Stress has been found to suppress the immune system allowing people to contract disease far faster than a person with less or no stress within their lives.…
Frequent experiences with stress and its impact on physical health are not unique. In fact, in a study made by S. Cohen, D. Tyrell and A. Smith (1993) entitled, “Negative life events, perceived stress, negative affect, and susceptibility to the common cold”, they found a strong relationship between stressful life events (for…
Outline how stress affects the body Stress and many stressors can effect the mind and body as a total unit. When one area is effected, it becomes a strategic systematic response through all body systems. Stress usually affects the thought process and the ability to pay attention or complete daily tasks. When the stress continues, it becomes more deep rooted issue that can lead to depression, chronic fatigue, lack of sleep, creates eating disorders (usually bulemia or binge eating), and eventually can cause pain to body parts.…
According to a quote in an article entitled Health Disparities and Stress by Nevid & Rathus (2003), “Stress is the physiological demand placed on the body when one must adapt, cope, or adjust (Nevid & Rathus, 2003). Stress can be a good thing because it helps keep a person alert, however extreme or extended stress can overwhelm the physical body which is not good.…
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…
Situations deemed to be a stressful and continuing threat to provoke flight or fight reactions to impose chronic stress upon the body if a person does not get sufficient opportunities for recovery in a non-stressful environment. The research evidence shows that contributed stress weakens the resistance to disease and further disrupts the functioning of metabolic and hormonal systems (Braveman & Gottlieb, 2014). Physiological tensions derived from stress make people susceptible to diseases such as immune system and cardiovascular and adult onset…
Stress; can have a major affect upon your body. It can be detrimental to your health. An increase to your stress levels stress can cause neurons to die which leads to headaches, anxiety and depression. In the digestive system there can be mouth ulcers and cold sores. In the circulatory system the constant elevated blood pressure and heart rate increases risk of blood clots or heart attack. Your breathing also quickens increasing your chances of colds or respiratory infection, while it also depressed your immune system leaving you more likely to get an infection. This has shown me that if you are constantly stressed out you will be more likely to continually be sick which in turn can lead to you becoming more stress. It is therefore important to constantly manage your daily stress levels.…
Abstract Research has shown a connection between stress and physical illness. Furthermore, who becomes ill under pressure may be regulated by other factors such as personality type. Several studies conducted confirm that stress is positively correlated with incidences of physical illness (DeVito, 1994). It is also becoming common knowledge that many physical diseases are either related to or can be exacerbated by excessive stress. Stress reduction is becoming a part of treatment and prevention of many diseases. Even insurance companies are paying for programmes such as ones that reverse heart disease, which include learning stress reduction techniques. Many studies have tried to link and explain the role of the immune system in the human stress response. The issue has even been given its own term, psychoneuroimmunology, meaning the study of the “direct causal relationship between stress and illness” (DeVito, 1994). For example, a study looking at wound repair in caregivers vs. non-caregivers found that caregivers, who were under significantly more stress than non caregivers, took an average of nine days longer to heal than non caregivers (Keicolt-Glaser, Marucha, Malarkey, Mercado, and Glaser, 1995). This study cited differences in the chemical immunological responses between the two groups.…

Have you ever heard of the term “fight-or-flight” stress response? You will feel this when you have more to worry about and handle then you are used to, or simply, when you are stressed. When your body is going through the fight-or-flight stress response, your body will make more hormones that will speed up your heart rate, give you a burst of energy, and make you breathe faster than normal (Healthwise, 2009). There are times when a little bit of stress could be useful, such as if you need to react quickly or if you need to work harder on something. For example, If you are trying to win a race or finish any work that is important on time. When you have stress that lasts for a long time or if you have stress too often, then your body will most likely have a bad effect from stress. When you are overly stressed, you can experience headaches, back pain, sleeping issues, and an upset stomach. Furthermore, stress can lower your immune system which will make it harder for your body to fight off the disease. With people who have existing medical problems, stress can make your problem worse. Stress has been known to make a person moody, depressed, and tense. This has caused many people to not do as well with their school or job, as well as having their personal relationships suffer.…
Cohen et al investigated the role of life stress on a person’s vulnerability to the common cold. He gave his participants questionnaires to fill out on the number of stressful left events they had encountered in the previous year and asked them to rate their level of negative emotion and degrees of stress. From this he then created a “stress index”. The participants were exposed with the common cold and after 7 days the number of participants that had developed the common cold were recorded. It was found that 82% of participants became infected and the chance of developing a cold was significantly correlated with the stress index. This study shows that there is a relationship between stress and illness, and that life stress and negative emotions may affect our immune systems adversely.…
