随着社会的进步、科学的发展,人们日益认识到吸烟有害无益。烟草燃烧后冒出的烟中含有毒素达几十种之多,由于吸入人体内的烟对呼吸系统、消化系统有直接的恶性刺激作用,因而吸烟又是胃及十二指肠、呼吸道感染甚至成为口、唇、舌、食道、肺癌等症的诱发因素。近年来运动医学工作者通过研究发现,经常进行体育锻炼能减少吸烟的危害。从烟草中吸入的一氧化碳会加重心脏的负担。因为,一氧化碳进入血液后,将导致运输量的减少。每天吸一包烟的人,血红蛋白运输氧的能力大约减少10%。为了提高氧的运输量,心脏必须要输出比不吸烟者多10%的血液,这个额外负担会诱发或加重心脏病的病情。
With the progress of society and the development of science, people are increasingly aware of the harmful and harmful effects of smoking. Tobacco smoke after burning out contains up to dozens of toxins, due to inhalation of the body of the smoke on the respiratory system, the digestive system has a direct malignant effect, and therefore smoking is the stomach and duodenum, respiratory tract infections and even Become a mouth, lips, tongue, esophagus, lung cancer embolism induced factors. In recent years, sports medical workers through the study found that regular physical activity can reduce the harm of smoking. Carbon monoxide inhaled from tobacco exacerbates the heart’s burden. Because carbon monoxide into the blood, it will lead to a decrease in traffic. People who take a pack of cigarettes a day reduce their ability to transport oxygen by about 10%. In order to increase oxygen transport, the heart must deliver 10% more blood than non-smokers, an additional burden that can induce or aggravate heart disease.
