肺癌

　　吸烟对身体有害众所周知，但诱惑人继续吸烟的一个想法就是：与不吸烟的人相比，我的身体并没有差到哪里去。也许并不是每一个吸烟的人都会得肺癌，但荷兰国立公共健康和环境卫生研究所最近指出，吸烟人的生活质量与不吸烟的人相差很多。美国《健康》杂志也刊登了“吸烟鲜为人知的20条危害”，详细说明吸烟人的生活质量是如何在不知不觉中下降的。
　　1. 香烟携带病菌。最新研究发现，香烟带有很多病菌，这些病菌会在吸烟过程中随之吸入体内。它们的致病机理尚不清楚，但香烟携带病菌是不可辩驳的事实。
　　2. 吸烟影响性功能。吸烟会影响血液循环，使生殖器血流量减少，进而导致性唤起困难(包括男性和女性)。2007年中国一项大规模调查还发现，20%的男性勃起功能障碍与吸烟有关。
　　3. 吸烟人睡眠质量差。美国约翰霍普金斯大学一项研究发现，一夜睡醒后，吸烟者依然困倦的几率是非吸烟者的4倍。研究人员分析指出，其原因是吸烟者夜间睡眠过程中，身体无法获得尼古丁，虽然看似呼呼大睡，实际上其睡眠会多次被打扰，睡眠质量下降。
　　4. 吸烟者骨头很脆弱。研究发现，女烟民每吸烟10年，骨矿物质密度就会降低2.3%―3.3%，骨质密度下降会导致骨折和骨质疏松症发病率大增。在绝经妇女中，这种危险更大。
　　5. 吸烟增加失聪失明危险。最新研究发现，与不吸烟者相比，吸烟者发生听力丧失的危险增加近70%。一项对2万多名男性的大规模调查发现，吸烟也会增加男性视力减弱的几率。吸烟还会增加产生视力头号“杀手”黄斑变性的可能。
　　6. 吸烟爱得牛皮癣。多项研究表明，每天吸烟与牛皮癣发病危险的增加有极大的关联性。每天吸烟超过20根以上，牛皮癣的发病危险就会水涨船高。
　　7. 吸烟者大多手脚冰凉。吸烟阻碍人体血液循环顺畅运行，让手脚供血不足，所以吸烟者容易手脚冰凉，手指和脚趾也更容易发生冻疮。
　　8. 香烟＋口服避孕药＝心脏病。英国最新研究发现，吸烟女性同时服用避孕药，会导致心脏病、中风等心脑血管疾病几率增加10倍。其原因是，吸烟会增加血黏度，更易导致血栓；而避孕药也会使血液变稠。“吸烟+避孕药”双重作用，使发病率又增1倍。
　　9. 吸烟降低药效。吸烟会影响肝脏酶处理药物的效果，因此吸烟者有时需要加大药量才能产生相同的药效。而戒烟之后，某些药物的用药量会随之下降。
　　10. 吸烟易诱发火灾。调查发现，吸烟者家庭成员发生烧伤的危险比无烟家庭成员高6.6倍。导致致命房屋火灾的各种原因中，吸烟占55%，位居首位。
　　11. 最近有研究表明，吸烟还会引起人的智商下降。以色列沙巴医药中心马克-韦泽博士及其研究团队发现，一天吸烟20支甚至更多的年轻人平均智商比不吸烟者低7.5点。在美国《国际瘾药杂志》发表的一篇论文中，研究人员介绍，作为研究对象的20211名新兵均无严重生理健康问题，28%每天吸烟1支以上，大约3%自称曾经吸烟，68%从未吸烟。
　　结果显示，不吸烟者平均智商为大约101，入伍前开始吸烟的男性平均智商为94。智商随日均吸烟量增加而下降，每天吸1至5支香烟者平均智商为98，每天吸烟超过20支者平均智商为90。

As we all know smoking is harmful, but the temptation to continue to smoke the idea is: Compared with non-smokers, there is no difference between my body and where to go. Maybe not every smokers will get lung cancer, but the Dutch National Institute of Public Health and Environmental Health recently pointed out that quality of life for smokers and non smokers a lot of difference. U.S. "Health" magazine has published "The 20 known hazards of smoking," Smoking detail how the quality of life of people unwittingly fall.
1. Cigarettes carry germs. Recent study found that cigarette with a lot of bacteria, these bacteria will be followed in the course of inhaled smoke. Their pathogenesis is unclear, but cigarette carrying bacteria is indisputable fact.
2. Smoking affect sexual function. Smoking can affect blood circulation, reducing blood flow to the genitals, leading to arousal difficulties (including male and female). China, a large-scale survey in 2007 found that 20% of men with erectile dysfunction and smoking.
3. Smokers sleep quality is poor. Johns Hopkins University study found that after a night awake, still weary of the risk of non-smokers smokers 4 times. Researchers analyzed that the reason is that smokers sleep during the night, the body can not get the nicotine, while seemingly asleep, in fact, be repeatedly interrupted his sleep, decreased sleep quality.
4. Smoker fragile bones. Study found that female smokers smoke every 10 years, bone mineral density is reduced by 2.3% -3.3% fall in bone density leading to fractures and osteoporosis incidence rate rose significantly. In postmenopausal women, this greater risk.
5. Smoking increase the risk of deaf blind. New research found that compared with non-smokers, smokers increase the risk of hearing loss occurred nearly 70%. More than one pair of 20 000 large-scale survey of men found that smoking also increases the probability of male vision changes. Smoking also increased the number one produce visual "killer" macular degeneration may be.
6. Smoking love psoriasis. Many studies show that the incidence of daily smoking and increased risk of psoriasis have great relevance. Smoking more than 20 a day more than the cancer risk would be rising in tandem with psoriasis.
7. Smoker mostly cold hands and feet. Smoking hinder the smooth running of human blood circulation, insufficient blood supply to hands and feet, so smokers easy cold limbs, fingers and toes are more prone to frostbite.
8. Tobacco + oral contraceptives = heart disease. UK latest study found that smoking women taking birth control pills at the same time, will lead to heart disease, stroke and other cardiovascular disease risk of an increase of 10 times. The reason is that smoking increases the blood viscosity, leading to more clots; and birth control pills also cause blood thickening. "Smoking + pill" double effect, so that they increase the incidence of 1 times.
9. Smoking decreased efficacy. Smoking may affect the liver enzyme treatment effect of drugs, so smokers need to increase the amount of drugs can sometimes produce the same efficacy. And smoking cessation, the dosage of some drugs will fall.
10. Smoking easily induced fires. The survey found that family members of smokers, the risk of occurrence of burn-smoking family members compared with 6.6 times higher. Housing fatal fire in a variety of reasons, smoking accounted for 55%, ranking the first.
11. Recent research shows that smoking will cause one of the IQ decline. Mark Sabah Medical Centre, Israel - Dr. Wei Ze and the research team found that smoking 20 cigarettes a day or more young people on average 7.5 IQ points lower than non-smokers. In the United States, "International Journal of Addiction Medicine," published a paper, the researchers introduced as subjects 20 211 new recruits had no serious physical health problems, 28% smoking one day more than about 3% claimed to have been smoking 68% never smokers.
The results showed that non-smokers the average IQ of about 101 enlisted men started smoking before the average IQ of 94. IQ increases with the average daily cigarette consumption decreased, smoked 1-5 cigarettes an average IQ of 98, smoking more than 20 per day the average IQ of 90.
