Outline and Evaluate research (theories/ and studies) into the relationship between stress and physical illness. 18 marks Stress is an example of a behavior and experience explained in physiological and psychological terms. Recently awareness has been highlighted concerning harmful effects of stress on our lives and how it can be managed and prevented. Stress is often associated with anxiety, strain, tension, distress and fatigue. The effects of stress include biochemical physiological and psychological changes, most show with ill health or unusual behavior.

- Stage 2, Resistance - The body adpats to stressor but becomes more susceptible to damage from the stress responses. - Stage 3, Exhaustion - The body's systems can no longer maintain normal functioning, possibly resulting in damage to immune system or stress related illness. There is increasing evidence that stress can cause illness by interfering with the immune system. The immune system protects the body from harmful viruses. When the stress response is activated, the activity of the immune system is slowed down. One of the earliest studies into the effects of stress on the immune system was conducted by Riley 1981 using mice. He placed the mice on a rotating turntable to cause stress. Riley measured the mice's lymphocyte count over a five-hour period and found they decreased, indicating suppression of the immune system. ...read more.
They found within 9 years of starting the study, 70% of the number who died were type A individuals. Therefore personality type and stress are closely related and together are related to the risk of CHD. The criticisms of these studies are that in the Riley study it raised ethical issues about the use of animals in laboratory experiments. Also, we cannot generalize findings from an animal study to humans because our pressures are completely different to animals. In Kiecolt-Glaser study there are possibilities that the findings may be affected by individual differences and so there may be an indirect relationship between stress and illness e.g. individuals who are stressed may smoke or drink more this leads to an unhealthy individual. Finally, Friedman and Rosenman did not use a mixed sample gender, and were only taken from California, so again the results cannot be generalized because of differences between genders and cultural variations can occur. ...read more.
