托福閱讀材料之經(jīng)常笑有利于健康

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

　　據(jù)兩份最新研究表明，大笑有益心臟健康，能延年益壽; 相反，憂郁增加早死的危險。

　　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.

　　其中一項研究的負責(zé)人、美國馬里蘭大學(xué)的邁克爾?米勒表示，堅持每天開懷大笑，能促進血液流動，像鍛煉身體一樣，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，北卡羅萊納大學(xué)的Wein Jiang負責(zé)的另一項研究，研究了1000個心臟病患者則表明，沮喪或者少笑常常與不健康習(xí)慣聯(lián)系在一起。比如，吸煙，吸毒等。同時，死亡的危險增加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稱笑會在心內(nèi)膜內(nèi)引起很大的變化，其功效類似于我們進行的有氧運動，而且避免了因為鍛煉而疼痛或肌肉緊張等不良影響。

　　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."

　　他還表示，笑并不能代替鍛煉。我們強烈建議每天都笑笑。一周堅持三次半小時以上的運動，每天笑15分鐘，這樣會對人們的脈管體統(tǒng)大有裨益。”
