    Why is it that many people who have suffered a major shock, such as divorce or death of a family member, seem to be weaker against a variety of major and minor illness? One common idea among psychologists has been that people could deal with suffering more effectively if they were able to understand and accept it. Indeed, many experts stress the value of expressing thoughts and feelings connected with upsetting events.

Recently, a team of medical researchers studied the links between describing psychologically painful events and long-term health. In one experiment healthy college students were asked to write about either personally disturbing experiences or ordinary topics over a period of four days. In the months afterwards, students who had chosen to show their inner thoughts and feelings in their writing visited the health center for illness much less often than those who had written about everyday topics.

In an experiment that followed, another group of healthy students were given the four-day writing exercises. Some chose to write about highly personal and upsetting experiences (including loneliness, problems with family and friends, and health). When questioned immediately afterwards, they said that they did not feel any better. However, their blood samples(样本) taken before and after the experiment showed evidence of an improved resistance to illness. The white cells that fight off bacteria and viruses had increased their reaction and sensitivity to these “invaders”. This trend continued over the following six weeks, when another blood sample was taken. Individuals who showed the best results were those who wrote about topics that they had actively kept from telling others about.

The researchers suggested that failure to face up to painful experience can be a form of stress itself, and can increase the possibility of illness. It follows, then, that actively dealing with a major shock makes possible its understanding and acceptance. The answer is not to suffer in silence. It may not always be possible to talk about personal problems, but writing them down will help the body to fight disease in the long run.
