The harm of mobile phone to senior three students

The mobile phone is an important item that we can't leave at any time, but who has really paid attention to its harm? First, mobile phone radiation will endanger people's work and sleep. For example, you are in a meeting and suddenly a phone call interrupts the boss who is talking about the key points. Do you think he will think you are a good employee who is dedicated to your work? It is very likely that this phone call will ruin your future! Many people will download some games on their mobile phones, and some people stay up until 3 or 4 o'clock to play those so-called games. Do you think you still have the energy to do a good job? Second, talking on the phone while driving is prone to accidents. According to the survey, the probability of an accident is twice as high as usual, which has endangered people's lives! Human life is precious, so it should not be put on the edge of danger, should it? Third, calling on public occasions interferes with others. For example, the library should be a quiet place. If a phone rings at this moment, won't you feel embarrassed? It is shameful to disturb others' study! Especially in a quiet place like a library! And, the teacher is teaching in class, and your mobile phone rings. Do you think the teacher will feel that he has received the respect he deserves? Fourth, the proliferation of true and false mobile phone short messages has caused social stability and turmoil! The wanton forwarding of pornographic short messages and the proliferation of false short messages have caused health threats to teenagers and social stability! Fifth, the constant' upgrade' of mobile phones has led to the aggravation of the comparison wind! I can't stand it, but I have to punch my face and be fat! Bring unnecessary burden to the family; Some people even sell their organs for vanity that does not belong to them, and ruin their health to buy what they need! Sixth, today's children are playing mobile phones at a young age; I have a 5-year-old cousin who comes to my house one day and picks up her mother's mobile phone to play. Is this a habit or a social atmosphere? Thought-provoking! The above hazards are all around us in reality, but we can't stop them in time! As a result, more and more adults and children are wearing glasses! Became a' small four eyes'! I'm here to appeal to the' low-headed family': Please put away your mobile phones to see the beauty of nature, care for your relatives around you, and care for your children to gain affection! If the mobile phone is an indispensable communication tool for you, what's the use for high school students, junior high school students and even primary school students to hold the mobile phone all day? Experts remind teenagers that using mobile phones is very harmful. According to Japan's Kyodo News Agency, the "Survey on Information Society and Teenagers' Consciousness" published by the Cabinet Office of Japan on December 16th shows that Japanese junior high school students use mobile phones for more than one hour every day, senior high school students for more than two hours, and even primary school students use mobile phones for nearly half an hour every day. 3% middle school students send and receive text messages more than 2 times a day, while 1% middle school students send and receive more than 5 times a day. Although this phenomenon has a long history, it is the first time to confirm that "mobile phone dependence" is indeed widespread among students in the form of large-scale investigation. Although it affects study and life, parents never agree that the school prohibits the use of mobile phones. In recent years, due to social disorder, parents have to keep in touch with their children at any time through mobile phones. Most primary school students use mobile phones with GPS satellite positioning function, so parents can grasp the approximate location of their children. For children, because mobile phones have become an important communication tool for modern people, if they don't have a mobile phone, it means that they may be blocked from the circle of friends. In this way, parents who did not intend to buy a mobile phone for their children had to pay for it in case their children were "alone". Keiko Shinohara, a Japanese education expert, thinks that in addition to satisfying that little vanity, mobile phones really do more harm than good to children. First, many children secretly send text messages in class, and they should hide under the covers and make phone calls when they sleep, which will affect their normal study and rest and even damage their eyesight. Second, phone calls and text messages deprive children of the opportunity to communicate face to face with others, which easily makes them timid, lonely and paranoid. Third, mobile phone fraud has been repeatedly banned, and there are many ignorant children who are deceived. It is easy to bring danger to children without judgment by exposing them to too much information. Fourth, the rapid upgrading of mobile phones makes it easy for children to covet vanity and blindly compare. Therefore, although the school stipulates that children must turn off their mobile phones during class, at other times, educators still agree on whether it is necessary for children to use mobile phones-whether they should not use them as much as possible. You probably modify it and it will come out. Not only do some people lose their sight and eat in order to play the king ... but there are also the following points: 1. Playing mobile phones late at night leads to drowsiness; 2. Playing on the phone leads to sudden death ... and so on ... When it comes to mobile phones, no one is unfamiliar, even three-year-old children will know how to use them. Now, with the progress of science and technology, the mobile phone has changed greatly, from a big and heavy mobile phone to a mobile phone that can be carried around with many functions. The mobile phone can be used not only for telephone communication, but also for surfing the Internet. Moreover, it can be used for video chat and taking photos, which saves the trouble of using a camera, and can also store information and listen to music. The mobile phone is equivalent to a small laptop. The mobile phone also has a special function, that is, it can save your life in an emergency, for example, in an emergency, mobile phones all over the world can dial the emergency number 112; The power of the invisible spare mobile phone is insufficient. In order to make it continue to be used, press the *337# key and the mobile phone will restart. After the completion, it is found that the power has increased by 5%. The phone was stolen? There is a way to make it useless for thieves. To check the serial number of the mobile phone, just type the *#6#15-digit serial number and it will appear on the screen of the mobile phone. Every mobile phone in the world has a unique serial number. Record this serial number and keep it well. If one day the mobile phone is unfortunately stolen, call the mobile phone provider and provide the serial number of the mobile phone. They will help you shield the mobile phone. In this way, even if the thief changes the SIM card, it still can't be used, so the mobile phone becomes useless to the thief. Nothing in the world is perfect, and mobile phones are no exception. Mobile phones are like poppies. They look bright and beautiful on the outside, but they contain poison inside. For example, mobile phone radiation is harmful to people's heads, and it will cause organic obstacles to people's central nervous system, causing symptoms such as head, dizziness, insomnia, dreaminess, hair loss, etc., and some people's faces are not infrequently affected by * * *. Many girls like to hang their mobile phones on their chests. However, research shows that hanging a mobile phone on the chest will have a certain impact on the heart and endocrine system. Even in the standby state with less radiation, electromagnetic radiation around the mobile phone will also cause harm to the human body. Putting it in your trouser pocket will kill sperm. According to the British report, Hungarian scientists found that the number of men who often carry and use mobile phones can be reduced by as much as 3%. Some medical experts pointed out that mobile phone users often hang around the waist of the human body, and the electromagnetic waves generated when they send and receive signals will radiate to the * * * or eggs in the human body, which may affect the user's reproductive function. I believe everyone knows the dangers of smoking, but would you be surprised if someone told you that the number of people killed by mobile phones is more than that of cigarettes every year? Statistics show that the number of mobile phone users in the world has reached three times that of smokers, so experts believe that the harm of mobile phones will be more serious than smoking. At present, more than 5 million people worldwide die of diseases caused by smoking every year. In 1977, reporter Lloyd first suggested that using mobile phones might have a bad effect on the brain. Because the number of people using mobile phones was very small at that time, this article did not attract people's general attention. In 1985, American scientist Lynn speculated that long-term use of mobile phones might lead to brain tumors. He also suggested: try to answer the phone only with your mobile phone, instead of dialing outside. Professor Yao Ke, director of the Institute of Ophthalmology, Zhejiang University, has proved through years of experiments that even if the mobile phone is used within the international radiation safety standards, it will still cause self-damage to human parts such as eyes for a long time. Electromagnetic microwave generated during cell phone answering will damage the lens of eyeball and destroy the function of cell communication and connection. The electromagnetic field of mobile phone may reduce bone density and lead to osteoporosis. After long-term use of mobile phone, too long contact with nickel material on the surface of mobile phone may lead to allergic reaction of skin, resulting in an itchy rash of "mobile phone dermatitis". When talking on the phone for a long time, it is also easy to get mobile phones. This is the arm pain caused by talking on the phone for a long time, because the elbow bends too much and for a long time, which overstretches the main nerve and hinders the blood flow to the nerve. Causing a tingling or numbness in the fingers from the elbow. It also affects pregnant women, if high microwave radiation causes abortion, fetal malformation or stillbirth. Low intensity can have adverse effects on some behaviors of offspring after birth. Knowing so many dangers of mobile phones, how to minimize the degree of harm. You can do the following: 1. Don't put it on the pillow; 2, don't hang on your chest; 3. You should put your mobile phone in your purse; 4, use headphones to answer the phone, try to control the call within half an hour; 5, don't let the phone touch the skin, often change hands when playing the phone. For the sake of everyone's safety and happiness, it is better to use mobile phones less.
