Watching a film that makes you laugh is good for your heart, according to a study. Researchers found watching a movie or programme that produces laughter has a positive effect on vascular function and is opposite to that observed after watching a war or horror film that causes mental stress. 电影暑期强档已经过去，告别了《哈利波特》迎来了《蓝精灵》，不管是不是喜剧片，《哈利波特》圆满的大结局以及《蓝精灵》制造的“低笑点”让这些片子成为老少皆宜的票房冠军。有研究显示，看一部能让您开心、乐呵呵的片子对身心都有好处，特别是心血管健康方面。据悉，一部能使人发笑的电影可以对人体的血管起到优化作用，这是相对看了战争片以及惊悚片后的比较而言的。 In the study volunteers watched segments of a funny film - such as There's Something About Mary starring Cameron Diaz - on one day and on another day watched the opening segment of the stressful war film Saving Private Ryan. 在实验中，研究员让志愿者看了喜剧片演的《关于玛丽的一切 》以及战争片《拯救大兵瑞恩》，在观察志愿者观看影片后的反映进行分析对比。 Lead investigator Dr Michael Miller from the University of Maryland School of Medicine in the U.S. said that when the volunteers watched the stressful film, their blood vessel lining developed a potentially unhealthy response called vasoconstriction, reducing blood flow. He said this finding confirms previous studies, which suggested there was a link between mental stress and the narrowing of blood vessels. |
