Laughter is good for the heart because it prolongs life while depression increases the risk of an early death, according to two new studies.


  A good bout 1 of laughter every day provides similar cardiovascular benefits asexercise because it stimulates 3 the blood flow, said Michael Miller 4, who headed one research team at the University of Maryland.


  On the other hand, depression -- or the lack of laughter -- is often linked to unhealthy habits such as smoking and drug addiction 5 and increases the risk of death by 44 percent, said Wein Jiang, who led a study of 1,000 heart patients for the University of North Carolina.


  Miller said laughter produced a "magnitude of change ... in the endothelium ... similar to the benefit we might see with aerobic 6 activity, but without the aches, pains and muscle tension associated with exercise"


  While laughter should not replace exercise, he said, "we do recommend that you try to laugh on a regular basis. Thirty minutes of exercise three times a week, and 15 minutes of laughter on a daily basis is probably good for the vascular 2 system."
 
 
 
 
每天笑15分钟可以使你的心脏更健康
  美国科学家的两项最新研究结果显示,笑能使人精神愉悦,同时还对心脏大有好处;相反,心情沮丧则不利于身体健康,甚至会增加早死的危险。


  据法新社3月8日报道,其中一项研究的负责人、美国马里兰大学的迈克尔·米勒表示,笑给心血管带来的好处就像锻炼可以给心血管带来好处一样,因为笑可以促使血液流通。而北卡罗莱纳大学的另一项研究则表明,心情沮丧或缺少笑容却常常与诸如抽烟、吸毒等不健康的生活习惯联系在一起,同时还能将死亡的危险增加44%。


  在调查过程中,米勒选择了20部让人发笑的喜剧片或是会使人紧张不安的悲剧片,并让20名平均年龄为33岁的,不吸烟、身体健康的志愿者观看这些影片。当志愿者观看影片时,研究人员检测他们血管内发生的变化。研究显示,观看悲剧片时,20名志愿者中有14人胳膊上的动脉血流量减少;相反,在观看喜剧影片时,20人中有19人的血流量增加。研究人员得到的结论是,在笑的时候,血流量会平均增加22%;而当人们有了精神压力时,血流量则会减少35%。


  对此,米勒表示,笑和做有氧运动时差不多,但笑可以使我们远离由运动带来的伤痛和肌肉紧张等不良影响。但是,他也同时表示,笑也不可能取代体育锻炼,两者应该有规律地同时进行。他说:“我们建议人们一周进行3次体育锻炼,每次30分钟;另外,每天要笑15分钟,这样会对人们的身体健康有好处。”
