吸烟影响唱歌吗？有多严重？

唱歌严谨的来说，是不让吸烟喝酒的，平常人吸烟都有害，何况是唱歌的人吸烟了。

　　Wassup Everybody, Wassup
　　
　　Recently, on youtube, I posted a comment regarding my policy on not accepting smoking clients (unless they were in the process of quitting).
　　
　　
　　 I received a few emails from singers who felt slighted by the fact that I would refuse service to someone who wanted to both smoke and sing.
　　
　　 Below is an email response that I sent to one of my youtube viewers who simply asked the question, "Why don't you work with smokers?"
　　
　　大家好
　　
　　最近，在YouTube上，我宣布了我的规定：跟我学唱歌的学生不能吸烟（除非他们中途退出我的教学） 。
　　我收到了一些抽烟的歌手的电子邮件，他们觉得我这是一种歧视。一个看了我的YOUTUBE网页的观众问我：“你为什么不教抽烟的人？ ”
　　
　　My response:
　　Hey "Anonymous,
　　My policy on smokers is not personal.It has nothing to do with me "judging" a person.
　　 For me, it's as simple as this:
　　
　　I'm a voice builder. My job is to help singers strengthen their instruments, building control, power, flexibility, and longevity. Smoking is just plain counterproductive to my work.
　　
　　我的回答是： "嘿“无名氏”
　　我的规定跟私人原因无关， 我当然不会因为谁抽烟而看不起他。
　　对我来说，事情很简单：我是一个“嗓音建设者”，我的工作是帮助歌手加强他们的“乐器”，学会控制，力量，灵活性，延长他们的歌唱寿命。吸烟的效果跟我的工作正好相反。
　　
　　Imagine how frustrating it would be if you were building a house, and every time you began building the framework for that house someone came along with a wrecking ball and knocked the whole thing to pieces.
　　
　　 You'd never get that house built.
　　
　　Smoking is a wrecking ball to the very framework of your vocal anatomy. In my experience, it has been frustrating to work with people who are actively destroying their instrument, as I am attempting to build it up.
　　
　　想象一下，如果你盖房子，每次你开始建设起一点新的框架，就有人来摧毁它，这是多么令人沮丧的事啊？这样的房子将永远也不会完工。
　　
　　从生理学来讲，抽烟对于声带，威力就跟拆房子的大铁锤差不多……根据我的经验，它百害而无一利。人们正在努力摧毁他们的“乐器”，而我的工作却是建立它。
　　
　　To be more specific, smoking impairs lung function by weakening the diaphragm and destroying healthy lung tissue. The foundation of my teaching method is based upon strengthening the reflexive muscular actions of the diaphragm and increasing lung volume.的How can I strengthen a respiratory system that is constantly under attack?
　　
　　更具体地讲，吸烟损害肺部功能，削弱横膈膜的力量，破坏健康的呼吸系统。而我的教学方法的基础是加强横膈膜的对抗力量，增加肺容积。 对于一个不断受到攻击的呼吸系统，我又如何去加强呢？
　　
　　Smoking also causes the vocal folds themselves to stiffen. The suppleness and flexibility of the vocal folds is crucial for pitch control, and it is especially important for hitting high notes with consistency and power.
　　
　　 And I won't even go into the very real threat of laryngeal cancer.
　　
　　
　　吸烟也导致声带的硬化。声带的柔软和灵活性对音高控制是至关重要的，要唱出连续的或者有力量高音，声带的柔软和灵活性也是必不可少的。 ...更不用说吸烟带来的咽喉癌的危险了。
　　
　　My overall point... As a singer, your body is your instrument.You need to respect it. Smoking does absolutely nothing good for your health in any way.
　　
　　
　　我的总结...作为一名歌手，你的身体是您的乐器。 你必须尊重它。吸烟并不是没有代价的。
　　
　　You can either stick to your guns - smoke - and listen as your voice becomes raspy and difficult to control... or you can begin attempting to quit. I'm sure it's not easy....But how much worse would you feel, if you lost your ability to sing freely?
　　
　　你可以继续拿着你的武器-香烟-——并眼看着你的声音变得越来越生硬和难以控制...或..开始尝试戒烟。.我相信戒烟很不舒服，但是如果你失去了自由歌唱的能力，你是不是会更难受呢？
　　
　　Just give it some thought, my friend.考虑一下吧，朋友。
　　
　　Love & Respect,爱与尊重，
