【背景】

美国一项研究显示，微笑“充分”的人寿命更长。

　　这项研究由密歇根州州立韦恩大学研究人员完成，研究论文刊登在最新一期《心理学》期刊上。

　　法新社24日援引研究论文报道，研究人员收集230幅上世纪50年代前参加美国棒球联赛的运动员照片，根据照片上人物微笑时嘴部、眼部和脸颊肌肉动作幅度，把他们的微笑分为“不笑”、“部分笑”和“充分笑”等类别。

　　根据出生年月、身体质量指数、婚姻状况、运动生涯长短等个人信息，研究人员确定身体状况等因素对这些运动员寿命的影响。

　　研究发现，“不笑”的研究对象平均寿命72.9岁；“部分笑”、即微笑时仅咧嘴的研究对象平均寿命75岁；“充分笑”、即微笑时带动脸部各相关肌肉的研究对象平均寿命79.9岁。

　　研究论文写道：“这一研究成果与其他一些研究成果类似，证明情绪与心理、生理健康和寿命有明显关联。”

　　论文作者说，尽管不清楚研究对象在镜头前是否自发微笑，但研究人员认为，即使这些运动员应摄影师要求微笑，他们微笑程度也能够“从总体上”反映各自潜在情绪状况。

英文原文

【英文原文】

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.

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

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.

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.

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. Ben Gruber, Reuters.
