  Psychosomatic medicine——Think yourself well

  身心医学:要相信,你的身体很棒

  You can. But it helps to think well of yourself in the first place

  你可以拥有很好的体魄。但首先,你要自我感觉好,这会有帮助的。

  THE link between mind and body is terrain into which many medical researchers, fearing ridicule, dare not tread.

  许多医学研究者都不敢探究躯体和心理的关系,因为他们害怕,踏进这一领域会受人嘲笑。

  But perhaps more should do so.

  但也许,研究这方面的人应该多一些才好。

  For centuries, doctors have recognised the placebo effect, in which the illusion of treatment, such as pills without an active ingredient, produces real medical benefits.

  几个世纪以来,医生已逐渐认可了安慰剂效应。因为患者会产生错觉,认为自己在接受治疗。比如,服用无活性成分的药片也能产生实际疗效。

  More recently, respectable research has demonstrated that those who frequently experience positive emotions live longer and healthier lives.

  根据最近的可靠的研究表明,平时积极乐观的人会活得更长久、更健康。

  They have fewer heart attacks, for example, and fewer colds too.

  比如,他们心脏病发作的次数更少,也很少感冒。

  Why this happens, though, is only slowly becoming understood.

  然而,人们才开始慢慢了解这种情况发生的原因。

  What is needed is an experiment that points out specific and measurable ways in which such emotions alter an individual's biology.

  人们需要的是做一场实验,明确这样的情绪是通过怎样具体的、可测量的方式来改变人的生理状况。

  And a study published in Psychological Science, by Barbara Fredrickson and Bethany Kok at the University of North Carolina at Chapel Hill, does precisely that.

  北卡罗来纳大学教堂山分校的芭芭拉·弗雷德里克松和贝瑟尼·可可就是按照这个思路做了一项研究,并在《心理科学》上发表了相关论文。

  Dr Fredrickson and Dr Kok concentrated their attentions on the vagus nerve. This nerve starts in the brain and runs, via numerous branches, to several thoracic and abdominal organs including the heart.

  弗雷德里克松博士和可可博士把注意力集中在迷走神经上。这对神经起于颅腔,通过无数分支与胸腔、腹腔的几个脏器相连。

  Among its jobs is to send signals telling that organ to slow down during moments of calm and safety.

  它的其中一项工作就是为器官发送信号,让它们在躯体平静、安宁的状态下放缓节奏。

  How effectively the vagus nerve is working can be tracked by monitoring someone's heart rate as he breathes in and out.

  他们通过监测一个人吸气、呼气时的心率,追踪记录迷走神经如何有效地工作。

  Healthy vagal function is reflected in a subtle increase in heart rate while breathing in and a subtle decrease while breathing out.

  如果吸气时心率略微增加,呼气时略微下降,则说明迷走神经工作正常。

  The difference yields an index of vagal tone, and the value of this index is known to be connected with health.

  两次心率之差构成迷走神经张力指数。人们都知道该指数与健康程度有关。

  Low values are, for example, linked to inflammation and heart attacks.

  例如,低指数就与炎症、心脏病发作几率有联系。

  What particularly interested Dr Fredrickson and Dr Kok was recent work that showed something else about the vagal-tone index: people with high tone are better than those with low at stopping bad feelings getting overblown.

  让弗雷德里克松博士和可可博士特别感兴趣的是最近的研究,因为它显示了迷走神经张力指数的另一个性质:与张力指数低的人相比,指数高的人能更好地防止不良情绪失控。

  They also show more positive emotions in general.

  研究也显示,指数高的人大体上情绪更乐观。

  This may provide the missing link between emotional well-being and physical health.

  这也许弥补了心理健康与生理健康之间缺失的环节。
