Smile - it could save your life
微笑有助于身体和心理健康
It is said that happiness is contagious. The supporting evidence is everywhere: from the streets of Rio during Carnival to more obscure celebrations elsewhere in the world. But long-term happiness may also be healthy. New York researcher Dr.Karina Davidson certainly thinks so. Dr. Davidson is a lead researcher in a 10-year study of more than 1,700 healthy men and women. The study revealed that people who are happy and content with their lives are 22% less likely than unhappy people to have a heart attack or suffer from symptoms of heart disease.
有人说，笑是可以传染的，到处都有证据支持这一点：从里约嘉年华的街头到世界各地其他庆祝活动。但是长期的快乐或许也对健康有益。纽约研究人员Karina Davidson博士非常确信这一点。Davidson博士领导研究人员对1700多名健康男女进行了为期十年的调查。调查披露，快乐和对生活满足的人比不快乐的人患心脏病的几率低22%。
We know that there is a direct physiological impact on the body of experiencing happiness or satisfaction or enjoyment. So, when you sit and watch a movie, say, or read a book that you really enjoy, your stress hormones go down and something cultural barrier reflex system is actually up regulated. We know an animal study said those things across time actually protect the heart.
我们知道，经历快乐，满足或欢愉时会对身体产生直接的生理影响。所以，当你坐着看电影，或者看自己喜欢的书的时候，你的压力荷尔蒙水平下降，而文化障碍反射系统会进行调节。我们知道，一项动物研究表示，长期来看，这些事情可以保护心脏健康。
The observational study is the first to show an independent relationship between positive emotions and coronary heart disease. But Dr. Davidson stresses that more work and clinical trials are needed before any treatment recommendations can be made. She says, though, that the study is the first step in providing doctors better insight and how to interact with their patients.
这是首个表明积极情绪与冠状心脏病之间存在独立联系的观察性研究。但是Davidson博士强调，在提出任何治疗建议之前还需要更多工作和临床试验。然而，她表示，该研究是为医生提供更好的视角，与病人进行更好的互动的第一步。
I think this may eventually shift healthcare providers to thinking about how we can help patients make sure that the things that make them happy stay in their routine. Because that is protective of your mental health for sure and this is one of the first studies to show it may also protect your physical health.
我认为，这项研究最终会让医保提供者思考我们如何帮助病人保持让他们高兴的事情成为习惯。因为这有益于精神健康，也是表明微笑有利于身体健康的首项研究。
Heart disease is the leading killer of men and women in most industrialized countries. Dr. Davidson says she hopes her report will shine a light on a new approach for prevention.
在大部分工业化国家，心脏病导致男女死亡的主要杀手。Davidson医生表示，她希望她的报道能够为新的预防方法打开思路。
