Investigating Stress and Illness Lucas Gr�ger IB1 25-10-09 Psychology HL Being stressed is sometimes a good thing but it often has negative effects on the person that is under stress. For example if you are stressed you have an increased chance of becoming sick. In a study 394 healthy participants completed a questionnaire designed to measure their stress level. They listed the stressful events they had experienced over the last year, assessed their ability to cope with these events and noted how often they felt negative emotions such as hostility, anger and depression.
