研究:多看喜劇片有益身心健康

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.

電影暑期強檔已經過去，告別了《哈利波特》迎來了《藍精靈》，不管是不是喜劇片，《哈利波特》圓滿的大結局以及《藍精靈》製造的“低笑點”讓這些片子成爲老少皆宜的票房冠軍。有研究顯示，看一部能讓您開心、樂呵呵的片子對身心都有好處，特別是心血管健康方面。據悉，一部能使人發笑的電影可以對人體的血管起到優化作用，這是相對看了戰爭片以及驚悚片後的比較而言的。

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.

在實驗中，研究員讓志願者看了喜劇片演的《關於瑪麗的一切 》以及戰爭片《拯救大兵瑞恩》，在觀察志願者觀看影片後的反映進行分析對比。

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.

領銜實驗的研究員Dr Michael Miller 說：“在實驗中，當志願者觀看驚悚片時，他們的血管收縮呈現不健康的反映，比如--減小血管直徑使供給某區域的血流減少，換句話來說就是血流量減少速度過快。這證明了先前實驗的結論--精神壓力大與血管收縮之間有直接的聯繫。”

However, after watching the funny movie, the blood vessel lining expanded. Overall, more than 300 measurements were made with a 30 to 50 per cent difference in blood vessel diameter between the laughter and mental stress phases. Dr Miller said: 'The take-home message here is that laughter is great for your heart.

與之相反，在觀看完喜劇片之後，志願者的“血管直徑”與觀看驚悚片後相比，呈現30%到50%的差異，結論證明，樂觀的心態、經常大笑有益心血管健康。
