In the evening, my neighbor Qin and I enjoyed the cool air in the pavilion downstairs in the community. Our neighbor Qin’s second treasure, Niu Niu, is our pistachio. Niu Niu is less than one year old. He has thick eyebrows, big eyes, and a tiger-like head. He is very cute. Not long after Qin sat down, Daming, the neighbor upstairs, also came. When he saw Niu Niu, he said, \”This kid is so cute and fun. I\’m here to tease him.\” After saying that, he took a sip in his hand. smoke, and then spray the smoke from his mouth on Niu Niu\’s face. Niu Niu was so smoked that his eyes and nose ran with tears, and he kept coughing. Finally, he burst into tears. I scolded him: \”Don\’t tease your children like this in the future. Don\’t you know that second-hand smoke is poisonous?\” Daming laughed and said, \”I\’m just teasing the children. It\’s okay. If second-hand smoke is poisonous, it will poison me first.\” In fact, There are quite a few parents like Daming who don’t take second-hand smoke seriously. \”If you want poison, poison me first.\” Yes, in their eyes, first-hand smoke is undoubtedly the most harmful. Second-hand smoke is nothing. Third-hand smoke has never been heard of. However, is this really the case? Let’s start with some popular science: what is second-hand smoke? Generally speaking, second-hand smoke refers to the mixed smoke formed by tobacco smoke exhaled by smokers. It is a form of passive smoking. It is the most widespread and serious form of indoor air pollution. What is third-hand smoke? After smoking, the tobacco smoke residue remaining on surfaces such as clothes, walls, carpets, furniture, and even hair and skin is third-hand smoke. Research by American scientists has confirmed that poisons remaining on clothing, carpets, furniture and other items are difficult to remove even with powerful cleaners, and they will remain for days, weeks or even months. Scientists say: Third-hand smoke is an invisible toxin and a silent killer. Third-hand smoke is more subtle than second-hand smoke and is less likely to attract people\’s attention, but it is more harmful. Whether it is second-hand smoke or third-hand smoke, the main harmful ingredients include carbon monoxide, tar, nitrosamines, nicotine, suspended particulates, PM2.5, etc., including more than 4,000 harmful chemicals and dozens of carcinogens. Researchers at the University of California in the United States conducted a study on 49 babies under 13 months old. They found that even if parents only smoked outside, nicotine could still be found in the air and dust in their homes. The results of testing the nicotine in the infant\’s urine and hair follicles showed that the nicotine content in the body of infants who passively inhaled their parents\’ \”third-hand smoke\” was seven times higher than that of infants from non-smoking families. When young children are still ignorant, most of them have close contact with their parents who have finished smoking or are smoking. The carcinogens brought by second-hand and third-hand smoke will cause great harm to children\’s physical and mental health. Triggering Asthma in Children Secondhand smoke is the main irritating factor that triggers asthma in children. An evaluation by a professional research organization in the United States shows that asthma causes American children to miss 14 million days of school every year, making it the most serious chronic disease affecting children\’s learning. The encounter between second-hand smoke and dust mites can easily cause respiratory diseases in children, such as pneumonia, bronchitis, and cough in children. And children from families where both parents smoke are much more likely to suffer from related diseases than children from non-smoking families. Multiple British studies on the impact on children’s hearingIt has been shown that otitis media, middle ear effusion, and abnormal tympanic membrane tension in children are all related to passive smoking. Research on the impact on children\’s height shows that children whose families smoke more than 10 cigarettes a day are on average 0.65 centimeters shorter than those from non-smoking families. The smell of cigarette smoke can easily irritate a child\’s nose. In the long run, the child will easily develop an aversion to the smell of smoke and food, causing anorexia. Affects children\’s intellectual development Nicotine produces cotinine when it is decomposed. Once the cotinine content in a child\’s blood increases, it may cause a decline in the child\’s reading, mathematics and reasoning thinking abilities. Increase the risk of meningitis in children. Researchers from the University of Nottingham in the United Kingdom and other institutions reported in the journal \”BMC Public Health\” that children under 5 years old who are often exposed to \”second-hand smoke\” are at a normal risk of contracting invasive meningococcal disease. more than twice. Damage to children\’s blood vessels There is a substance in the blood and urine of children who are harmed by second-hand smoke that affects the dilation of blood vessels and causes blood clots and inflammation. If parents smoke 20 cigarettes a day, the concentration of this substance in the child\’s blood is nearly 50% higher than that of normal children, and the concentration in the urine is nearly 30% higher. In 2015, the Hypertension Department of Ruijin Hospital Affiliated to Shanghai Jiao Tong University School of Medicine discovered that a 5-year-old child\’s systolic blood pressure was as high as 180, and his blood vessels were as hardened as an 80-year-old man. The doctor pointed out that the child\’s arteriosclerosis was related to his father\’s heavy smoking every day. Statistics on factors leading to leukemia and cancer in children with Xinhua Hospital show that more than 60% of children with leukemia have second-hand smoke pollution in their families, indicating that smoking plays an important role in the causative factors of leukemia. Weakening Children\’s Immune Function Secondhand and third-hand smoke increases the content of harmful trace elements such as cadmium in the environment, reduces the content of vitamin C in children, weakens children\’s immune system function to a certain extent, and makes them susceptible to diseases. Toxic substances in second-hand and third-hand smoke that cause tooth decay in children will have adverse effects on the mineralization process of children’s oral flora and deciduous tooth development, and by affecting the development and function of salivary glands, reduce the production and effectiveness of saliva. Moreover, second-hand or third-hand smoke causes damage to children\’s respiratory systems and causes nasal congestion, which increases the time they have to breathe through their mouths and increases the probability of tooth decay in children. There is a public service announcement that says: If you start smoking around your children from the time they are born, by the time they are 5 years old, they will be equivalent to inhaling 100 packs of cigarettes. Second-hand smoke and third-hand smoke are not child\’s play. Sometimes, what hurts a child the most is the family members who accompany him day and night. So, let us take action immediately to create a clean and smoke-free environment for our children so that they can grow up healthily physically and mentally. The whole family takes action to create a smoke-free environment together. For the sake of children and themselves, quitting smoking is the best solution. Dads who really can\’t quit smoking need to rinse their mouths, wash their hands, wash their faces, and change their coats before touching their children after smoking. Mothers can punish their smoking fathers by doing regular house cleaning, including cleaning blind spots, scrubbing furniture, changing curtains, etc. They should also wash their hair, take baths, and change clothes frequently. It is advisable to choose non-smoking areas in public places. When taking children out, stick to \”no smoking areas\”. If there is no smoke-free area, please have your child sit in a seat with good ventilationplace away from smokers. You should also pay attention to the antioxidant function of vitamins in your diet, and try to let your children eat more fresh vegetables and fruits. At the same time, let the children drink more water, exercise more, sweat and urinate more, and accelerate the elimination of nicotine and other harmful substances in the body. In addition, don’t forget to educate your children to develop a sense of self-protection and stay away when you see someone smoking. In fact, the biggest source of harm to children from second-hand smoke is actually their own family members. There is a public service announcement about the ban on smoking in Thailand: two children took to the streets and borrowed fire from those who were smoking, saying that they wanted to use it to light cigarettes. So those who were smoking began to teach their children earnestly. The child finally gave them a note: You care about me so much, then, do you care about yourself? And what I want to say most is: when you smoke, you can temporarily forget your own health, but please don\’t forget the children around you.
