Laughter is Good for the Heart
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."

其中一項研究的負責人、美國馬里蘭大學(xué)的邁克爾·米勒表示，笑給心血管帶來的好處就像鍛煉可以給心血管帶來好處一樣，因為笑可以促使血液流通。而北卡羅萊納大學(xué)的另一項研究則表明，心情沮喪或缺少笑容卻常常與諸如抽煙、吸毒等不健康的生活習(xí)慣聯(lián)系在一起，同時還會將死亡的危險增加44％。
對此，米勒表示，笑會在心內(nèi)膜內(nèi)引起某種變化，其效果和做有氧運動時差不多，但笑可以使我們遠離由運動帶來的傷痛和肌肉緊張等不良影響。
但他同時也表示，笑也不可能取代體育鍛煉，兩者應(yīng)該有規(guī)律地同時進行。他說：“我們建議人們一周進行3次體育鍛煉，每次30分鐘；另外，每天要笑15分鐘，這樣會對人們的脈管體統(tǒng)大有裨益。”
