笑一笑，十年少：保持微笑的五大好处

When Mother Teresa said "Everytime you smile at someone, it is... a gift to that person, a beautiful thing" she was right. One study conducted by Hewlett Packard found that seeing another's smile stimulated the heart and brain more so than eating chocolate, having sex, or receiving money. This was particularly true when viewing the smile of a child. Additionally, research has demonstrated smiling may actually be contagious. Research published in the Scandinavian Journal of Psychology examined mimicry, the tendency to mimic the emotional expressions of those around us, and found that it is actually hard to frown when someone else is smiling.
特蕾莎修女曾经说过：“你每次对别人笑都是礼物，是美好的东西。”她是对的。惠普公司进行了一项研究，发现看见别人的微笑对心脏和大脑的刺激胜过吃巧克力、做爱或是收到钱。看到小孩的笑容的时候尤其是这样。另外，研究还发现微笑是会有传染性的。《斯堪的纳维亚心理期刊》上发表了一项研究，检测了人倾向于模仿周围人情感表达的这一特性，发现别人在笑的时候是很难皱起眉头的。

4) Your Relationships Will Be Stronger
4. 微笑能增进感情

People who smile more may have longer and more successful marriages. A 2001 study by Keltner and Harker evaluated women's smiles in yearbook photos and found that those who had more prominent smiles were more satisfied with their marriages at age 52. A similar study published in 2009 found a correlation between smiles in photographs and divorce rates. The larger the smile, the less likely divorce was later in life. Conversely, those with the smallest smiles or no smiles, were five times more likely to be divorced. So what does the smile have to do with marriage? People who smile more tend to be more optimistic, joyful and emotionally stable which lends itself to healthier relationships.
爱笑的人的婚姻通常更长久，更成功。2001年，凯尔特纳和哈克在一项研究中评估了年鉴照片中女性的笑容，他们发现笑容比较灿烂的妇女在52岁时对婚姻更满意。2009年有一项类似研究发现照片中的笑容和离婚率有相关性。笑得越是灿烂，日后离婚的可能性就越小，相反，那些笑意浅淡或是根本不笑的，离婚的可能性有五倍那么高。所以微笑和婚姻有什么关系呢？爱笑的人更乐观，快乐，有着稳定的有利于健康的积极情绪。

5) Give a Boost to How Others Perceive You

People who smile more are generally perceived to be more trustworthy, sincere, sociable and competent than their frowning peers. Additionally, a study by Orbit Complete found that 70 percent of people find women more attractive when they are smiling than when they are wearing makeup.
人们通常觉得爱笑的人比爱皱眉头的同事更可靠，真诚，善交际且有竞争力。另外，“Orbit Complete”做过一项研究，发现70%的人觉得女性笑起来的时候比化了妆更有魅力。
