Correlation Study Between Stressful Life Events And Illness.

Extracts from this document...


Correlation Study Between Stressful Life Events And Illness Introduction: The first article I am writing about is written by Simon Green, the title of the text is 'Under Pressure How To Combat Stress' the article featured in Psychology Review. This article is Text A. The second article I chose to write about was written by Sheila Hayward, the title is 'Stress, Health and Psychoneuroimmunology' this article also appeared in Psychology Review. I selected Text A as it tells you how to manage the stress you are suffering and also because it consists of both text and images. I chose Text B as it informs you how stress can make you ill if prolonged. It focuses on the endocrine and the nervous system. This article also uses useful images. I chose not to use a source called 'Lingering Anger' as it didn't involve much information on how ill health and stress are related and the images used weren't very informative. The theory behind linking stress and illness is that the immune system is at a lower level so the person is more prone to illness and infections. Text A states 'Stress can be a short-term or long lasting'. It goes on to say short-term effects include increased blood pressure, a raised heartbeat and the release of stress hormones (Text A, paragraph 1, line 8). ...read more.


When cells aren't replaces as fast as they die it is called immunosuppression. T-cells begin by 'helping' B-cells and eventually respond to infections. Text A, page 1, paragraph 2 says 'the suppression of the immune system may leave the person vulnerable to other illnesses and infections. The high levels of impact on the immune system means that the cells in the body can't function properly, the high level of white blood cells doesn't necessarily mean a healthy immune system as these cells may not producing a response to infections (Text B, page 4, column 2). In conclusion stress can be both physical and psychological, it also affects every one differently. It is also shown that the response to stressors is controlled by two systems , both of which affect the way the immune system functions. From research there is no definite cause and effect relationship between stress and illness but the variables that may be used in the research can't be generalised over the population e.g. the amount of Glucocorticoid in a persons blood sample will be different in each individual this may be due to inheritance and individual differences. Both of the sources were written to inform readers and both were formal pieces. The language used was not colloquial, as people who had not studied psychology would not understand such technical terminology. ...read more.


The results from this study agreed with the positive correlation that Rahe et al. found after doing the same type of correlation study another study that supports the findings is another Rahe study in which he found that there was an increase of illness in those who had a higher life events score. A result that supported Kobassas study was that there was male who had a high amount of stressful life event points but a low illness score this maybe because the person is hardy and because everyone is different it may just be because genetics made the person hardier than others. Evaluation: The first weakness of this study is that it was all conducted in one area thus making the research endocentric. Also the study didn't take into account the daily hassles that people may have and the events and illnesses that were rated were based on a group discussion and these events would affect each individual differently. The investigation could be improved by: asking more people to complete the questionnaire and giving the questionnaire to equal amounts of males and females. Also by using a random sample instead of an opportunity sample as a random sample would avoid most bias. The fact that cause and effect cannot be inferred is also a weakness, as it is not proved that a stressful life event causes illness. ...read more.

    Temperature: temperature affects reproduction in humans especially in men. The scrotum where sperm are produced is 2 degrees lower than core body temperature. Raising the temperature by a few degrees results in a decline in sperm count and motility. Men suffering from cryoptorchidism, where the testicles are located above the scrotum, closer to central body temperatures, frequently suffer from low sperm counts.
