俗话说，笑一笑十年少，笑是人类所有表达中最美的行为。有研究表明，经常笑有利于健康，笑更可以促进血液循环和腹肌收缩。有专家指出，100次的捧腹大笑中所吸收的氧气相当于做10分钟滑船器运动的吸氧量。所以大家要保持心情愉悦，经常笑就对啦。下面来看看具体的阅读材料吧！
Laughter is good for the heart because it prolongs life while depression increases the risk of an early death, according to two new studies.
据两份最新研究表明，大笑有益心脏健康，能延年益寿;；相反，忧郁增加早死的危险。
A good bout of laughter every day provides similar cardiovascular benefits as exercise because it stimulates the blood flow, said Michael Miller, who headed one research team at the University of Maryland.
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，坚持每天开怀大笑，能促进血液流动，像锻炼身体一样，提高心血管健康。
On the other hand, depression -- or the lack of laughter -- is often linked to unhealthy habits such as smoking and drug addiction 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.
另一方面，北卡罗莱纳大学的Wein Jiang负责的另一项研究，研究了1000个心脏病患者则表明，沮丧或者少笑常常与不健康习惯联系在一起。比如，吸烟，吸毒等。同时，死亡的危险增加44%。
Miller said laughter produced a "magnitude of change ... in the endothelium ... similar to the benefit we might see with aerobic activity, but without the aches, pains and muscle tension associated with exercise"
Miller称笑会在心内膜内引起很大的变化，其功效类似于我们进行的有氧运动，而且避免了因为锻炼而疼痛或肌肉紧张等不良影响。
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 system."
他还表示，笑并不能代替锻炼。我们强烈建议每天都笑笑。一周坚持三次半小时以上的运动，每天笑15分钟，这样会对人们的脉管体统大有裨益。
