笑--每個(gè)人都會(huì)的一個(gè)簡(jiǎn)單的動(dòng)作。笑充滿了我們的生活。它不僅表達(dá)了我們內(nèi)心的愉悅，更有利于我們的健康。尤其是對(duì)心臟有好處，那到底好在哪里呢，讓我們一起來(lái)看個(gè)究竟。
 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 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.
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.
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."
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."
