Can Stress Make You Sick? 精神压力会使你得病吗？

1.Scientists are now studying a new field of research called psychoimmunology. It is based on the that people who are depressed or have a lot of stress are more likely to become sick. Researchers have recently found a connection between diseases and stressful situations. To test this theory, psychoimmunologists are trying to find a link between the brain and the immune system..

科学家们现在正在研究一个新的研究领域，称作精神免疫学。它基于这样一个观点：处于精神压抑状态或经受太多精神压力的人比较容易得病。研究者现在已经找到了疾病和精神压力环境之间的联系。

2.The immune system in our bodies fights the bacteria and viruses which cause disease. There ore, whether or not we are likely to get various diseases depends on how well our immune system works. Biologists used to think that the immune system was a separate, independent part of our bodies. Recently, however, they have found that our brain can affect our immune system. This discovery indicates that there may be a connection between emotional factors, such as stress or depression, and illness.

我们身体力的免疫系统与致病的细菌和病毒作斗争。因此，我们会不会得各种各样的疾病取决于我们的免疫系统工作得好不好。生理学曾认为免疫系统是我们身体的一个分开的独立的部分。然而，最近他们发现我们的大脑能够影响我们的免疫系统。这个发现表明了可能在压抑或精神压力等感情因素和疾病之间有联系。

3.Although many doctors in the past suspected a connection between emotional factors and disease, they had no proof. Scientists have only recently discovered how the brain and the immune system function, Before this, no one could see a link between them. As a result, medical science never seriously considered the idea that paychological factors could cause disease.

虽然过去也有许多医生猜测在感情因素和疾病之间有联系，但他们没有证据。科学家只是在最近才发现大脑和免疫系统的功能。在这之前，没有人找到它们之间的联系。据于此，药物学家从未认真地考虑过心理因素会致病这个观点。

4.Several recent studies showed a connection between stress and illness. For example, researchers went to an American military school to study the students. By studying the cadets, blood, they found that many were infected with a virus which causes mononucleosis, a common glandular disease. Of the infected students, only 5 percent achieve, but they were not very good students. Ina similar study, researchers studied a group of student nurses. They focused on cold sires, which are also caused by a common virus. Many student nurses carried the virus in their

blood, but few of these infected nurses actually developed cold sores. The nurses who did develop cold sores were the ones who described themselves as generally unhappy people.

最近的几个研究显示了精神压力与疾病之间的联系。譬如，研究者来到美国军事学校研究学生。通过化验学生的血液，他们有许多人携带着一种能引起单核白血球增多症的病毒，一种常见病。在被感染的学生中只有5%实际得病。这些得病的学生中大部分受到学业上的压力并想有所进取，但他们不是很好的学生。在类似的研究中，研究者观察了一群学生护士。他们的研究集中在唇疱症上，它也是有一种常见的病毒引起的。许多学生护士的血液中携带这种病毒，但没几个受感染的学生实际发展到得唇疱症。发展成唇疱症的护士都是些自诉是日常不快乐的人。

5.In addition to these results, which support their theory, researchers are also looking for proof that stress can damage the immune system. Researchers studies recently bereaved people, i.e., people whose loved ones have just died, because they are more likely to become ill or die. By examining the immune system of recently bereaved people, the researchers made an important discovery. They examined some white blood cells, called lymphocytes, which are an important part of the immune system. They were not functioning properly. The fact that they were bot working correctly indicates that severe paychological stress, such as a loved one?/FONT>s death, may damage an important part of our immune system, namely, the lymphocytes.

除了这些支持他们理论的结果，研究者也寻找精神压力破坏免疫系统的证据。研究者们研究了那些新丧亲人的人们，等等，这些人刚死去亲人，往往自己也容易得病或死亡。测试这些丧亲者的免疫系统，研究者得到了一个重要的发现。他们检测了一些这样的人的白血球，也叫淋巴细胞，是免疫系统的一个重要部分。它们不能正常的起作用。它们不能正常工作这一事实说明了如丧亲这样严重的心理压力可能破坏我们免疫系统的一个重要部分，即淋巴系统。

6.There is still no positive proof of a connection between the immune system and psychological factors. Researchers also say that the results of the studies on bereaved people could have a different explanation. For example bereaved people often sleep and eat less than normal, or may drink alcohol or take medication. These factors can also affect the immune system. More research is needed to clearly establish the connection between the immune system and psychological factors.

到此仍没有关于免疫系统和心理因素间存在联系的正面证据。研究者也说关于丧亲者的研究结果可有另外的解释。例如，丧亲者通常比正常人睡眠和进食少，或者可能喝酒或者服药。这些因素也可能影响免疫系统。需要更多的研究来清楚的建立起免疫系统和心理因素之间的联系。
