189 Benefits from Occasional Stress

189 从偶尔的压力中受益

“Humans should not try to avoid stress any more than they would shun food, love or exercise.” Said Dr. Hans Selye, the first physician to document the effects of stress on the body. While here’s on question that continuous stress is harmful, several studies suggest that challenging situations in which you’re able to rise to the occasion can be good for you.

汉斯·泽利厄博士是第一位证明压力对身体有影响的医生。他说:“人们不应该再逃避压力了。就像人们不逃避食物、爱情和锻炼一样。”尽管毫无疑问,持续的压力会对身体有害,但也有几项研究表明,那些你能够应付的具有挑战性的境遇对你的发展是有益的。

In a 2001 study of 158 hospital nurses, those who faced considerable work demands but coped with the challenge were more likely to say they were in good health than those who felt they stress that you can manage also boost immune function. In a study at the Academic Center for Dentistry in Amsterdam, researchers put volunteers through two stressful experiences. In the first, a timed task that required memorizing a list followed by a short test, subjects through a gory video on surgical procedures. Those who did well on the memory test had an increase in levels of immunoglobulin A, an antibody that’s the body’s first line of defense against germs. The video-watchers experienced a downturn in the antibody.

在2001年对158名医院护士所做的研究中发现,那些面临着巨大工作压力但又能很好地应对这些挑战的人比起那些不堪承受工作压力的人来说更有可能说自己很健康,而且这还使得他们可能提高自己的免疫功能。在阿姆斯特丹牙医学科研中心的项研究中,研究者让志愿省接受两次压力试验。首先是一个计时任务。要求记住一系列的条目,随后接受一个简短的测试,就是要求他们看完一个血淋淋的外科手术的实况录像。结果发现,那些在记忆测验中表现出色的个体,他们体内的免疫球蛋白A的含量有所增加免疫球蛋白A是人体内抵御细菌的第一道“防线”。录像观看者经历了抗体上的一个低迷时期。

Stress prompts the body to produce certain stress hormones. In short bursts these hormones have a positive effect, including improved . “They can help nerve cells handle information and put it into storage,” says Dr. Bruce McEwen of Rockefeller University in New York. But in the long run these hormones can have a harmful effect on the body and brain.

压力可以促使身体分泌某种压力荷尔蒙。在短时间内这些:荷尔蒙能产生积极的效果,其中包括增强记忆功能。纽约洛蔚大学的布鲁斯·麦凯文博士说:“这些荷尔蒙能帮助神经细胞处理信息并加以储存。”但是从长远看,这些荷尔蒙对身体和大脑都会产生有害的影响。

“Sustained stress is not good for you,” says Richard Morimoto, a researcher at Northwestern University in Illinois studying the effects of stress on longevity ,”It’s the occasional burst of stress or brief exposure to stress that could be protective.”

伊利诺伊州西北大学的一位研究压力对长寿的作用的研究者理查德·天本真—说:“持续的压力对人体有害,但是偶尔的压力或者短时间的压力却能对人体有保护作用。”
