Mobile phone is an important item that we can't live without at any time, but who has really paid attention to its harm? First, mobile phone radiation will harm 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 dedicated and good employee? 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 will stay up until 3 or 4 to play those so-called games. Do you think you still have the energy to do a good job? Second, driving on the phone 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, make phone calls in public to disturb others. For example, a library should be a quiet place. Wouldn't you be embarrassed if the phone rang at this time? It is shameful to disturb others' study! Especially in a quiet place like the library! Also, your mobile phone rang while the teacher was in class. Do you think teachers will feel that they have received due respect? 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 threatened the health and social stability of teenagers! Fifth, the constant' upgrade' of mobile phones has led to the intensification of the wind of comparison! I can't stand it, and I have to beat my face! Bring unnecessary burden to the family; Some people even sell their organs for vanity that doesn't belong to them, ruin their health and buy what they need! Sixth, children nowadays are playing mobile phones at a young age; I have a 5-year-old cousin who came to my house one day and picked up her mother's mobile phone to play. Is this a habit or a social atmosphere? Thought-provoking! The above hazards are around us in reality, but we cannot stop them in time! As a result, more and more adults and children wear glasses! Became a' small four eyes'! I hereby appeal to the' low-headed family': Please put away your mobile phone to see the beautiful scenery of nature, care for your loved ones around you, and care for your children to gain affection! If the mobile phone is your indispensable communication tool, what's the use of high school students, junior high school students and even primary school students holding mobile phones all day? Experts remind teenagers that using mobile phones is very harmful. According to Kyodo News, the "Information Society and Youth Awareness Survey" released by the Cabinet Office of Japan on February 16 shows that Japanese junior high school students use mobile phones for more than 1 hour every day, senior high school students use mobile phones for more than 2 hours, and even primary school students use mobile phones for nearly half an hour every day. 30% middle school students send and receive text messages more than 20 times a day, and 10% middle school students send and receive text messages more than 50 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 the 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 master the approximate location of their children. For children, because mobile phones have become an important communication tool for modern people, if there is no mobile phone, it means that it 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 themselves in case their children were "left alone". Keiko Shinohara, a Japanese education expert, thinks that besides satisfying a little vanity, mobile phones really do more harm than good to children. First, many children secretly send text messages in class and hide under the covers to make phone calls when sleeping, which will affect 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 many ignorant children have been deceived. Exposing children to too much information can easily bring danger to children without judgment. Fourth, mobile phones are updated quickly, which makes it easy for children to covet vanity and blindly compare. Therefore, although the school stipulates that children must turn off their mobile phones in class, at other times, educators still agree that it is necessary for children to use mobile phones-whether they should try not to use them. You probably modified it and came out. Not only some people are blind, but also the following points: 1 Playing mobile phones late at night leads to drowsiness. 2 Playing mobile phones leads to sudden death ... Wait for the following points ... 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 a lot, from a big and heavy mobile phone to a portable mobile phone with many functions. Mobile phones can be used not only for making phone calls, but also for surfing the Internet. Moreover, you can video chat and take photos, which saves the trouble of using a camera, and you can also store information and listen to music. A mobile phone is equivalent to a small notebook computer. 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 rescue number112; The invisible standby mobile phone is low in power. To keep it in use, press the *3370# key and the phone will restart. After completion, it was found that the power increased by 5%. The phone was stolen? There are ways to make it useless to thieves. To view the serial number of the mobile phone, just enter *#06# 15 serial number and it will appear on the screen of the mobile phone. Every mobile phone in the world has a unique serial number. Write down 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 block your mobile phone. In this way, even if the thief changes the SIM card, it still can't be used, and the mobile phone becomes useless to the thief. Nothing in the world is perfect, and mobile phones are no exception. Cell phones are like poppies. They look bright, but they contain poison. For example, mobile phone radiation is harmful to people's heads, and it will cause organic disorders to people's central nervous system, causing dizziness, insomnia, dreaminess, hair loss and other symptoms. It is not uncommon for some people's faces to be affected by * * *. Many girls like to hang their mobile phones on their chests. However, research shows that hanging a mobile phone on your chest will have a certain impact on your heart and endocrine system. Even in the standby state with less radiation, the electromagnetic radiation around the mobile phone will 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 30%. Some medical experts pointed out that mobile phone users often hang around the waist of the human body, and the electromagnetic waves generated when sending and receiving signals will radiate to the human body's * * * or eggs, 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 more people die from mobile phones than 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, the reporter Lloyd suggested for the first time that the use of mobile phones may have adverse effects on the brain. Because few people used mobile phones at that time, this article did not attract people's general attention. 1985 American scientist Lynn speculated that long-term use of mobile phones may lead to brain tumors. He also suggested: try to answer the phone only with your mobile phone, and don't call outside. Professor Yao Ke, director of the Institute of Ophthalmology of 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-harm to human parts such as eyes for a long time. The electromagnetic microwave generated when the mobile phone is answered will damage the lens of the 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 the mobile phone, the contact time with the nickel material on the surface of the mobile phone is too long, which may lead to skin allergic reaction and pruritus of "mobile phone dermatitis". Talking on the phone for a long time is also easy to get a mobile phone. This is arm pain caused by a long phone call, because the elbow bends too much for too long, which overstretches the main nerve and hinders the blood flow to the nerve. Causing the fingers at the elbow to tingle or numb. If high microwave radiation causes abortion, fetal malformation or stillbirth, it will also affect pregnant women. Low intensity will have adverse effects on some behaviors of offspring after birth. Knowing so many hazards of mobile phones, how to minimize the hazards. Can do the following: 1, don't put it on the pillow; 2. Don't hang it on your chest; 3. You should put your mobile phone in your wallet; 4. Answer the phone with headphones and try to control the call within half an hour; 5, don't let the phone touch the skin, often change hands when playing with the phone. For everyone's safety and happiness, it's better to use mobile phones less.
