关于吸烟危害的英语演讲稿
Smoking is a greater cause of death and disability than any single disease, says the World Health Organisation. According to their figures, it is responsible for approximately five million deaths worldwide every year. Tobacco smoking is a known or probable cause of approximately 25 diseases, and even the WHO says that its impact on world health is not fully assessed. Heart attack and stroke UK studies show that smokers in their 30s and 40s are five times more likely to have a heart attack than non-smokers. Tobacco contributes to the hardening of the arteries, which can then become blocked and starve the heart of bloodflow, causing the attack. Often, smokers who develop this will require complex and risky heart bypass surgery. If you smoke for a lifetime, there is a 50% chance that your eventual death will be smoking-related - half of all these deaths will be in middle age. Smoking also increases the risk of having a stroke. Lung problems Another primary health risk associated with smoking are lung cancer, which kills more than 20,000 people in the UK every year. US studies have shown that men who smoke increase their chances of dying from the disease by more than 22 times. Women who smoke increase this risk by nearly 12 times. Lung cancer is a difficult cancer to treat - long term survival rates are poor. Smoking also increases the risk of oral, uterine, liver, kidney, bladder, stomach, and cervical cancers, and leukaemia. Another health problem associated with tobacco is emphysema, which, when combined with chronic bronchitis, produces chronic obstructive pulmonary disease. The lung damage which causes emphysema is irreversible, and makes it extremely difficult to breathe. Harm to children Smoking in pregnancy greatly increases the risk of miscarriage, is associated with lower birthweight babies, and inhibited child development. Smoking by parents following the birth is linked to sudden infant death syndrome, or cot death, and higher rates of infant respiratory illness, such as bronchitis, colds, and pneumonia. Nicotine, an ingredient of tobacco, is listed as an addictive substance by the US authorities. Although the health risks of smoking are culmulative, giving up can yield health benefits regardless of the age of the patient, or the length of time they have been smoking. Future impact By 2020, the WHO expects the worldwide death toll to reach 10 million, causing 17.7% of all deaths in developed countries. There are believed to be 1.1 billion smokers in the world, 800 million of them in developing countries.

戒毒,戒烟,借酒的演讲稿200字
戒烟其实靠个人自制力，如果妄想借助别的东西来代替，你是没有准备好戒烟，我会建议你暂时别戒烟，等确定要戒烟再戒烟。
我和你分享下我的经历和一些建议。
还有戒烟时反作用很多，注意协调。
我从2004年开始抽烟，到2015年11月戒烟。
这次戒烟前烟量是30根左右\\\/天。
中间戒烟戒过2次。
08年戒烟一次，11年戒一次，08年戒烟的时候从110斤涨到130斤，戒烟2个月11年戒烟的时候 从130涨到140斤，戒烟1个月这次15年戒烟到今天，2016-10月31日 也增重10多斤，现在快160斤了。
以上是我个人的情况，每次戒烟都未买任何替代品。
戒烟困难的原因是：我们人类做任何事都需要有个反馈，比如关门有响声，照相有咔嚓声，这样才能知道我已经做了某事，还有追求一个人的时候，最怕的也是对方根本不给任何反馈，我到底成功了多少，还要多少努力才能成功，这个完全不知道。
减肥、戒烟都是这样。
不知道我少抽这一根烟，我离成功戒烟又靠近了多少，不抽对身体的好坏具体是什么样的完全是模糊的，所以戒烟难。
建议是如下：1、戒烟了身体内部机能失去平衡，重量涨得太快了。
代价太大了。
所以要戒就彻底的戒，不然还是别随便戒烟。
2、我小孩子2012年12月出生的，现在只要偶尔咳嗽，我心理就会想是不是因为我在生他前抽烟导致他肺受影响了。
。
心理会很内疚，毕竟自己可以对自己的身体负责，但是小孩子因我们的自私行为，而无辜受影响，对小孩子来说挺不公平的。
3、抽烟不只是烟钱的问题，有时候为了找个抽烟的环境，空调房不能抽，车上不能抽，KTV包间不能抽，办公室不能抽，，你就为了这一点自残行为得东躲西藏
戒了省事
4、其实抽烟更多的是一种心理暗示，像我戒烟6个多月了，我还是经常会梦到抽烟，因为某一种行为太习惯了，现在我都忘记烟味了，但是还是忘记不了抽烟时候 那种感觉。
刚戒烟时，是尼古丁依赖，戒烟2星期以后，已经属于心理信赖了。
你想想戒烟这么痛苦，又抽起来，以后再戒烟，再经历一次这样的痛苦，那我把话说重点，就是狗改不了吃屎。
。
。
我以前也复吸好几次，又再戒，感觉之前的苦都白受了。
。
所以你现在得问问自己，是不是真心想戒烟。
好了，手打太多了。
希望我不复吸。
希望你想清楚，如果要戒烟就下好决心，如果只是戒烟戒着玩的，最好别戒烟，不然对身体影响更大。
请你写一篇戒酒,戒烟、禁毒的演讲稿70字
现实中，青少年吸毒已成为一个触目惊心的严重问题。
来自国家禁毒委员会办公室的数字表明，我国最近几年青少年吸毒的比例始终在吸毒人口中占80%左右。
据不完全统计，16岁以下的少年吸毒人数有所增加，青少年已成为最易受到毒品侵害的“高危人群”。
目前，学校毒品预防教育工作在认识上还存在着一些误区：一是怕学生知道毒品。
认为禁毒教育会引发学生的好奇心，促使他们冒险尝试;二是认为禁毒教育是公安部门的事，与学校无关。
这些认识误区的一个前提，就是目前在校学生吸毒者罕见。
事实上，毒品蔓延的速度相当快，若等到毒品在校园时再来教育，则为时已晚。
由此可见加强禁毒教育，做好超前预防工作，是解决青少年吸毒问题的根本途径和出路。
学校将通过思想政治课中的法制教育、法律知识竞赛、通过请区公安分局负责禁毒教育的警官到学校做报告，以案例分析的形式让学生了解毒品的危害等形式增强学生的法制意识，提高自我保护能力。
以自我互动教育、体验教育、亲子双向教育、集中授课等形式，帮助青少年在实践中掌握法律知识，在体验中增强法制观念。
如果条件允许可以通过建立法律服务设施，开展经常性的法律咨询，为青少年提供及时有效的法律服务

Soy food good for womenWomen who ate soy regularly as children have a lower risk of breast cancer, American researchers report. And men who eat fish several times a week have a lower risk of colon cancer, a second team of researchers have told the American Association for Cancer Research. The studies add to a growing body of evidence about the role of diet in cancer. Cancer experts now believe that up to two-thirds of all cancers come from lifestyle factors such as smoking, diet and lack of exercise. The US National Cancer Institute and researchers at the University of Hawaii found that women who ate the most soy-based foods, such as tofu and miso, when aged 5 to 11, reduced their risk of developing breast cancer by 58 per cent. It was not clear how soy might prevent cancer, though compounds in soy called isoflavones have estrogen-like effects. A second study showed that men who ate fish at least five times a week had a 40 per cent lower risk of developing colorectal cancer compared with men who ate fish less than once a week. Many kinds of fish are rich in omega-3 fatty acids, which interfere with the cyclooxygenase-2 or COX-2 enzyme. COX-2 affects inflammation, which may play a role in tumour growth.据美国研究人员报告，儿童时期经常吃豆类食品的女性患乳腺癌的风险较小。
另一组研究人员则向美国癌症研究协会提出，一周吃几次鱼的男性患结肠癌的几率较小。
这两项研究进一步证明了饮食对于防癌的作用。
癌症防治专家认为，在所有种类的癌症中，多达三分之二都是由吸烟、节食及缺乏锻炼等不健康的生活方式造成的。
美国全国癌症研究所和夏威夷大学的研究人员发现，在5岁至11岁时经常吃豆腐、味噌等豆类食品的女性患乳腺癌的几率要低58%。
至于豆类食品为什么可以防癌还不清楚，不过大豆中所含的名叫异黄酮的化合物具有雌性激素的作用。
另一项研究表明，一周吃鱼至少五次的男性患结肠癌的风险要比那些一周都吃不到一次鱼的男性低40%。
很多鱼类中所富含的Omega-3脂肪酸能够抑制环氧化酶2的活性。
环氧化酶2会引起发炎，这可能会刺激肿瘤的生长。
If you're middle-aged and your memory's not what it used to be, check the bathroom scale, researchers warned, suggesting overweight people tend to score more poorly on tests of memory than their thinner peers do. The findings suggest that a heavier weight in middle age may mean a higher risk of dementia later in life. Reporting in the journal Neurology, the researchers speculated that higher rates of cardiovascular disease or diabetes might help explain the link. But it's also possible that substances produced by fat cells, such as the hormone leptin, have direct effects on the brain. The study compared mental abilities to body mass index (BMI), a measurement of weight in relation to height used to define overweight and obesity. A BMI of 25 or more indicates overweight, and 30 or more is obese. The study also investigated the relationships between BMI and cognitive function in 2,223 healthy men and women between the ages of 32 and 62 in France through the use of four cognitive tests. The study found a higher BMI was associated with lower cognitive test scores. Results from a test involving word memory recall show people with a BMI of 20 remembered an average of nine out of 16 words, while people with a BMI of 30 remembered an average of seven out of 16 words. 研究人员提醒，如果你已步入中年，发现自己的记忆力不如从前，那么你得小心体重了。
研究表明，超重的人记忆测试的得分要比较瘦的人低。
研究发现，体重偏大的中年人今后患老年痴呆症的可能性较大。
研究报告在《神经学》期刊上发表，研究人员推断，心血管疾病及糖尿病的高发现象可以解释其中的原因。
此外，脂肪细胞所产生的物质，如瘦体激素，对大脑有直接影响。
此项研究将调查对象的智力与体重指数进行了对比。
体重指数指的是身高和体重之间的比例，主要用来衡量一个人是否偏胖或肥胖。
体重指数为25或25以上的人偏胖，达到30或30以上的人则为肥胖。
研究人员还对体重指数和认知功能间的关系进行了研究，他们在法国对2223位年龄在32岁至62岁间的健康男女进行了认知测试。
研究发现，体重指数越大，认知测试的得分越低。
其中一项单词记忆的测试结果表明，在16个单词中，体重指数为20的人平均能记住9个，而体重指数为30的人平均只能记住7个。
People who do not get enough sleep are more than twice as likely to die of heart disease, according to a large British study released Monday.Although the reasons are unclear, researchers said lack of sleep appeared to be linked to increased blood pressure, which is known to raise the risk of heart attacks and stroke.A 17-year analysis of 10,000 government workers showed those who cut their sleep from seven hours a night to five or less faced a 1.7-fold increased risk of death from all causes and more than double the risk of cardiovascular death.The findings highlight a danger in busy modern lifestyles, Francesco Cappuccio, professor of cardiovascular medicine at the University of Warwick's medical school, told the annual conference of the British Sleep Society in Cambridge.A third of the population of the UK and over 40 percent in the US regularly sleep less than five hours a night, so it is not a trivial problem, he told reporters.Previous research has highlighted the potential health risks of shift work and disrupted sleep. But the study by Cappuccio and colleagues, which was supported by British government and US funding, is the first to link duration of sleep and mortality rates.The study looked at sleep patterns of participants aged 35-55 at two points in their lives - 1985-88 and 1992-93 - and then tracked their mortality rates until 2004.The results were adjusted to take account of other possible risk factors such as initial age, sex, smoking and alcohol consumption, body mass index, blood pressure and cholesterol.Cappuccio said it was possible that longer sleeping could be related to other health problems such as depression or cancer-related fatigue.In terms of prevention, our findings indicate that consistently sleeping around seven hours per night is optimal for health, he said.(Agencies) 本周一公布的一项大规模英国调查表明，睡眠不足的人死于心脏病的几率是睡眠充足者的两倍多。
目前其中的原因尚不清楚，但研究人员称，睡眠不足会导致血压升高，从而增大患心脏病和中风的风险。
一项针对1万名政府职员、长达17年的跟踪调查表明，每晚睡眠时间从七个小时减少到五个小时或更少的人因各种原因而死亡的几率是睡眠正常者的1.7倍，而且死于心血管疾病的风险也增加了1倍多。
沃里克大学医学院的心血管药物学教授弗朗西斯哥•卡普西奥在英国睡眠学会在剑桥召开的一年一度的研讨会上说，这一研究成果揭示了忙碌的现代生活中潜在的危险。
他在接受记者采访时说：“三分之一的英国人以及超过40%的美国人每晚的睡眠时间常常达不到五个小时，所以这个问题不可小视。
”此前有调查发现轮班及睡眠中断会对健康产生潜在威胁。
但卡普西奥及其同事的这项调查则首次揭示了睡眠时间长短与死亡率之间的关系。
该调查由英国政府和美国基金提供资助。
该调查对年龄在35岁至55岁之间的人在1985年至1988年以及1992年至1993年两个阶段的睡眠模式进行了探究，并对这一人群截至2004年的死亡率进行了追踪。
调查还考虑到了调查对象的初始年龄、性别、是否吸烟喝酒、体重指数、血压及胆固醇指标等其它可能的风险因素。
卡普西奥说，睡眠时间过长也可能导致如抑郁症及癌因性疲乏等其它健康问题。
他说：“就预防而言，我们的研究结果表明，每晚睡眠时间持续保持在七小时左右最益于身体健康。
