英伦广角 重金属摇滚乐的疯狂摇头被揭露存在罕见危险（在线收听）

Heavy metal music can be hazardous to your health—at least, in what appear to be rare circumstances.

重金属乐可以对你的健康造成危害，至少在极少数的情况下会出现危险。

A 50-year-old fan who recently rocked out at a Mot?rhead concert developed bleeding in the brain that required surgical repair. He had celebrated the band’s signature fast tempo music by headbanging—that is, violently pitching his noggin to and fro in time to the music.

最近在摩托头乐队的演唱会上，一位50多乐迷跟着摇滚乐疯狂摇头，导致脑部出血，需要外科手术修复。他当时在用疯狂的摇头来庆祝该乐队的标志性快节奏音乐，合着音乐来回的猛烈的摇动他的头。

A month after the concert, the man experienced an intense headache. Doctors found on the right side of his brain a chronic subdural hematoma: an injury where blood collects under the brain’s outer protective membrane. Surgeons fixed him up. The case study is in the journal The Lancet. [Ariyan Pirayesh Islamian, Manolis Polemikos and Joachim K. Krauss, Chronic subdural haematoma secondary to headbanging]

在演唱会后一个月，这个人感到头痛很严重。医生发现在他大脑的右侧有慢性硬膜下血肿：受伤的地方是在大脑外部的保护膜收集血液的地方。外科医生帮他进行了修复。这个病例研究被发表在《柳叶刀》医学杂志上。

Headbanging is usually considered relatively harmless, though it can cause whiplash or shorter-term head or neck pain. A follow-up scan of the Mot?rhead fan revealed that a benign cyst may have made him more vulnerable to brain injury than your standard heavy metal enthusiast.

尽管疯狂摇头可以引起颈部扭伤，短期头痛和颈痛，但是它通常被认为是相对来说没有伤害的。后续对该摩托头乐队的头部扫描表明，一个良性囊肿可能使他比一般的重金属乐爱好者更容易遭受脑损伤。

The study authors say devotees may maintain their headbanging habit, as such bleeds are so uncommon. Even more uncommon are brain injuries sustained at concerts featuring the music of Mozart, Mahler or even Rachmaninoff.

研究人员表示鉴于这样的脑部出血很少见，那些爱好者们可能会继续维持他们的疯狂摇头习惯。更罕见的是，头部损伤持续不断的在莫扎特，马勒，甚至拉赫玛尼诺夫等音乐会中出现。——Dina Fine Maron
