Laughter is said to be older than language. Even animals laugh. It is one of the most natural and beneficial things you can do for your body and mind. Whether you snort, chortle, cackle, exude a huge belly laugh, or have a weird little giggle that's ever so characteristic of you, laughter is the best medicine. It's a preventative medicine for almost every ailment! Science agrees and urges us all to lighten up and squeeze out more laughs every day. Researchers says that people who love to laugh are healthier and happier. Here's a list of ten reasons why.
笑一笑，十年少。对动物来说也是。关于修养身心你能做的最自然最有利的事就是笑了。不管你是扑哧一笑，哈哈大笑，呵呵笑，捧腹大笑还是带有你特征的奇怪的咯咯笑，笑都是最好的药。笑是几乎所有疾病的预防药。科学家对此表示同意并敦促我们放轻松，每天多挤出笑容。研究人员也表示爱笑的人一般更健康快乐。下面是爱笑的10个好处：

10.They have reduced stress.
10.减轻压力
In a recent study at the Indiana State University, researchers found that laughter can not only reduce stress, but also improve the chances to survive cancer and HIV. The simple act of chortling can soothe tension throughout the body and also lower the body's stress hormones.
最近在印第安纳州立大学有一项研究，研究员发现笑声不但能减轻压力，还能提高癌症和艾滋病的治愈率。哈哈大笑这样一个简单的行为就能舒缓紧张的身体，减少应激激素，何乐而不为？

9.They have decreased feelings of anxiety and fear.
9.舒缓焦虑感和恐惧感
Since feelings of anxiety and fear can be detrimental to your emotional health, people who love to laugh have a huge advantage over those who are grumpy and never laugh at all. That's because laughter releases the feel-good hormones dopamine, serotonin and endorphins. These little guys work to improve your mood, enhance your experiences and ease feelings of fear and anxiety.
因为焦虑感和恐惧感会不利于情绪健康，所以爱笑的人比脾气暴躁的人和从来不笑的人更有优势。这是因为笑会释放感觉良好的激素，如多巴胺，羟色胺和内啡肽。而这些小家伙们又会努力改善你的情绪，增加你的经验，减轻你的焦虑感和恐惧感。

8.They have improved respiratory health.
8.改善呼吸健康
Laughter flushes the lungs with fresh air and helps you breathe more deeply. People who love to laugh inadvertently stretch their lungs, increase their heart rate and reinvigorate their entire body when laughing. This is equal to a splash of cool, fresh, rejuvenating water for the respiratory system.
笑有利于肺部吸入新鲜的氧气，有利于我们进行深呼吸。当爱笑的人在笑的时候，他们的肺部扩张，心率增加，全身恢复精力。这就相当于给我们的呼吸系统来了一瓶干净酷爽的回春水。

7.They have lower chances of heart disease.
7.远离心脏病
A study conducted at The University of Maryland found that there is a link between laughter and cardiovascular health. Laughter causes the tissue that composes the lining of blood vessels to expand, allowing for better blood flow. In other words, people who love to laugh improve the function of their blood vessels and increase blood flow. This helps protect their heart from diseases.
马里兰大学的一项研究发现笑和心血管健康之间存在着联系。笑会导致血管内壁组织扩大，有利于血液充分流动。换句话说，爱笑的人可以改善血管的功能，增加血流量。这有助于他们远离心脏病。

6.They have an endless supply of natural pain reliever.
6.用之不尽的天然止痛药
People who laugh freely don't need morphine and other pain killers quite as much. That's because the feel-good hormones released into the system when you laugh not only help ease fear and anger, but also help to relieve pain. No wonder more and more people are turning to laughter yoga to ease their troubled minds and bodies. They want to tap into this and other benefits of laughter.
爱笑的人不需要吗啡和其他止痛药。那是因为当你笑的时候，身体里会释放感觉良好的激素，不仅有助于缓解恐惧和愤怒，也有助于缓解疼痛。难怪越来越多的人正在转向大笑瑜伽，放松他们的身心。他们想挖掘笑这样或那样的好处。

5.They have reduced aggression tendencies.
5.攻击性更弱
People who love to laugh tend to be significantly less violent and aggressive in society. That's because laughter offers a healthy outlet for pent up negative emotions of anger and aggression. A simple chuckle; for example, can help defuse a conflict. Even better, laughing has a relaxing effect on the whole body that lasts for up to 45 minutes. This provides important psychological benefits for jolly people.
爱笑的人大大减少了社会暴力和侵略性。这是因为笑为压抑已久的愤怒和侵略的负面情绪提供了一个健康的发泄方式。例如，一个简单的笑就可以化解冲突；更好的是，笑能让全身有一个长达45分钟的持久放松效果。这对快乐的人们提供了重要的心理帮助。

4.They have an enhanced immune system.
4.免疫系统增强
Another health benefit that people who love to laugh enjoy as a result of decreased stress hormones is improved oxygen intake and circulation. Laughter is also a healthy outlet for negative emotions. All of these things come together and boost immunological responses, ensuring laughers stay healthy. The number of T-cells in the body also increases when you laugh, giving the immune system a boost.
爱笑的人另一个好处是，笑在减少了应激激素后，能改变含氧量，改善氧气流通。笑也是发泄负面情绪的健康方法。所有的这些东西加在一起，能提高免疫应答，确保爱笑的人保持健康。当你笑的时候，你体内T细胞的数量也增加，也就增强了免疫系统。

3.They get a good, regular mini-workout.
3.得到规律有效的小型锻炼。
According to research conducted at the University of Maryland School of Medicine in Baltimore, laughter may give the same positive effect as exercise. This finding comes as no surprise considering that people who love to laugh get their shoulders moving and contract their abdominal muscles during an episode of laughter, thereby getting a welcomed mini-workout.
根据巴尔的摩的马兰大学医学院的研究，笑能带来和锻炼同样好的效果。但我们对这一结果感到并不惊讶，因为爱笑的人在笑的时候肩膀在运动，腹部肌肉也相应收缩，因此爱笑的人获得了规律的小型锻炼。

2.They have a radiant, youthful glow.
2.更青春，更活力
People who love to laugh have a radiant glow about them that not only makes them look youthful and beautiful, but also attracts others to them. That's right, laughing can actually make you more attractive to others. According to research, men prefer women who laugh at their wit, while women tend to prefer a man who can make them laugh. A beaming smile is the most becoming accessory for your face.
爱笑的人往往自带光环，不仅让他们看起来更年轻，更漂亮，也更有吸引力。没错，笑让你能吸引他人。根据研究发现，男人更爱笑得理智的女人，女人则更喜欢能逗笑她们的男人。一个喜气洋洋的微笑是你脸上最好的化妆品。

1.They have stronger relationships.
1.较强的人际关系
People who bring laughter in their life (IE: by watching a funny movie or TV show, going to a comedy club etc.) and view life through the colorful lens of humor, strengthen bonds of love and increase intimacy. Because laughter can trigger happy feelings and foster emotional connection it also enhances relationships. Break down barriers to your happiness in all your relationships, promote group bonding and enhance teamwork by embracing laughter.
生活里充满欢笑的人（即：通过观看有趣的电影或电视节目，去喜剧俱乐部等），生活中会有五彩缤纷的幽默镜头，爱情会有强力粘合剂，与他人关系也更亲密。因为笑可以触发快乐的感觉，培养情感上的联系，同时也加深了人际关系。通过笑传达你的快乐，可以打破所有的关系的障碍，推动团队团结，提高团队工作效率。
Life's so much better and brighter when we share laughs with one another.
当我们与他人分享笑容的时候，我们的生活是如此多娇。让我们多笑笑吧。
