Children are our future and hope, moreover, they are the trust of families and parents. The burden of illness caused by children’s diseases is huge and the emotional impact on families is unbearable. However, in the past decade, the number of childhood tumors in China has increased tenfold in many places. What is the reason for such a result? As we know, children are in the process of development, many organs and tissues are not yet functional, and their ability to detoxify is much lower than that of adults. For example, children and adults in the same passive smoking environment, testing each for secondhand smoke residue cotinine (a nicotine metabolite) in the blood, will find that children have more than double the amount of cotinine in their blood than adults. So caring for children’s health must prevent them from being exposed to tobacco smoke and other pollutants. Women are the protectors of the family and society, taking on the important role of mothers and future qualified mothers in the family. The absence of mothers in the family would be a great disaster, and protecting the health of women is protecting each of our families. Since any toxic and harmful substances that women are exposed to during pregnancy, breastfeeding and caring for their children may cause health effects on the fetus and young children. Our research has found that maternal smoking even affects the academic performance of children and adolescents. The reason for this is that children are often accompanied by their mothers, and their mothers’ smoking causes an increase in respiratory diseases in children, and children miss more school than children in their non-smoking families, as a result of which these children do not do well in school, and the pressure to study makes them inclined to smoke, entering a new vicious circle. Passive smoking is a common cause of lung cancer, heart disease and cerebrovascular disease. However, the pathogenesis process is not taken seriously because it is a cumulative result that is not very significant. Recently, the Capital Medical University accepted the project “Measurement of indoor smoke pollution in Beijing”, and through laboratory studies of smoke pollution indoor environment, and level measurements of smoke pollution in restaurants, offices, and bars, it was found that smoke can be expressed in the air as a concentration of tiny particles PM2.5, and after measurements, it was found that indoor smoking causes an extreme decrease in air quality, and tests showed that when indoor The test shows that when there is no one smoking the air cleanliness is good, the concentration of tiny particles PM2.5 in the air is only 37, but within five minutes from the time someone smokes the first cigarette, the air quality drops 8-10 times, the concentration of tiny particles PM2.5 in the air can reach 330, in 15 minutes of time always remain in the concentration of PM350. Even if you stand at 6 meters from the burning cigarette, the pollution concentration in the air is more than 4 times higher than the safety standard. Not to mention the impact of the cumulative increase in smoking on the air. This suggests that one cigarette is enough to cause air deterioration and that it is dangerous for nonsmokers to breathe in the same room as smokers. Studies have found that short-term exposure of individuals to high levels of smoke can lead to premature death or morbidity in patients with heart and lung disease, increased medical visits for respiratory patients, increased onset of cardiovascular disease and emergency room visits, increased coughing and shortness of breath symptoms, and more serious harm to children and asthma patients. And working in a smoky environment for long periods of time can lead to an increase in patients with lung cancer, lower lung function in patients, increased chronic respiratory disease in children, and a host of other serious health damages. A national survey found that half of the population currently lives in a passive smoking environment almost every day, while most women are non-smokers, and service workers working in many public places and offices, almost every day to work in a smoke-polluted indoor environment, if the 8 hours of work are breathing with second-hand smoke, the actual equivalent of their own initiative to smoke a pack and a half of cigarettes. Therefore, prohibiting people from smoking in public places and workplaces protects women and children, and protects the health rights of non-smokers. The experience of many countries shows that restricting smoking to protect non-smokers also reduces active smoking behavior and protects the health of all citizens. In May 2008, the Beijing Municipal Government announced the “Certain Provisions on the Scope of Smoking Prohibition in Public Places in Beijing”, which came into effect on May 1, 2008. This regulation for the first time raised the scope of the smoking ban from general public places to a more comprehensive scope, including workplaces, from hospitals to universities, high schools and elementary school, from offices to restaurants, bars and cafes, from airports and train stations to stadiums and gyms, from cultural venues to hotel rooms and parks, and put forward a comprehensive ban on smoking, seeking to improve the maximum scope of people’s living and working environment and To protect people’s lives and health. We hope that all citizens will actively support the governmental decree to ban smoking in the city and contribute to the creation of a smoke-free environment and a smoke-free city as your social responsibility as a qualified citizen!
