The harm of mobile phone to teenagers

First, the harm of using mobile phones to students

1. Affect the formation of students' good quality

In recent years, it is nothing new for students to cheat with their mobile phones in various exams. In June, 2004, our school found that some students cheated with their mobile phones in the final exam. In 2004, the college entrance examinations in Qianjiang, Shishou, Nanzhang and other places in Hubei used mobile phone fraud cases, such as the cheating case in the college entrance examination in Dianbai. With the popularization of mobile phones and the enhancement of their functions, the phenomenon of cheating by using mobile phones is increasing day by day, and it is becoming more and more ingenious. For example, if you wear headphones in your sleeve and pretend to think with your hands close to them during the exam, you are actually listening to the answers from your mobile phone. Girls are more convenient, and some simply wear headphones on their ears and cover them with long hair. The invigilator is hard to find. In addition, it is common for students to lie on their mobile phones. In particular, some students who are tired of learning lie about reviewing their lessons at school when playing games in Internet cafes. Some students even play tricks on teachers and classmates with text messages. Cheating, lying or sending false information are all manifestations of dishonesty. If they are not stopped in time and guided correctly, they will bring serious harm to the formation of students' good quality.

2. The bad information of mobile phone short messages is harmful to students' mental health.

After the Internet, there has been a new favorite of middle school students in recent two years-SMS. Mobile phone short message is a scientific and technological innovation in the field of communication, which provides a fast and simple modern means for people to exchange information and convey emotions. However, this is also a highly confidential "grey zone". While people enjoy free communication, human weaknesses such as lust indulgence and moral anomie are also revealed. Among them, yellow information is the most harmful. In the past, "erotic jokes" and "pornographic jokes", which were mostly circulated among adults, were spread to minors through SMS. Seeing that many young hearts are polluted by this, some media exclaim "Who will kill the yellow poison of SMS", but they all suffer from no effective countermeasures. According to the survey, about 79% of the students said that they used it for "text flirting". 74% of students send more than 10 every week. 44% of students send more than 20 messages. Judge Shang of Haidian District Court in Beijing pointed out that young students' long-term exposure to pornographic information is easy to form a psychologically unhealthy reading pleasure. Too many text messages can make people mentally disordered. If mobile phone communication replaces direct communication, they will not accept the differences between people, and they will not know how to respect others. Glenn, a psychologist at Royal College, University of London, UK? Wilson said that in 80 clinical experiments, the IQ of people who often send text messages at work will drop by 10%, which is equivalent to not sleeping all day, and will only drop by about 4% after smoking marijuana. Moreover, the content of short messages is generally unfiltered, and middle school students who are in the "incomprehensible" stage are easily attracted by unhealthy content and go astray. In addition, teenagers are prone to compare with others when using mobile phones.

3. Disrupting classroom discipline

It is no accident that the mobile phone often rings in class, and students send short messages and whisper interesting information they receive, which disturbs the class order.

4. Cell phone radiation affects students' health.

Long-term radiation of mobile phones is not good for students' physical development. Professor Gail, who studies human cranial nerves and cells at the University of London, wrote that the brain cells and DNA structures of normal mice will be damaged after four hours of continuous exposure to radio waves with a frequency range similar to that of mobile phones. Studies have shown that when children use mobile phones, the radiation absorbed by their brains is 50% higher than that of adults. Liang Xuanmei of Lanzhou Hospital of Integrated Traditional Chinese and Western Medicine said that nowadays, many teenagers use mobile phones, thinking that this has little impact on their health. In fact, teenagers' immune system is weaker than that of adults, so they are more susceptible to radiation. It has been proved that cell phone radiation can damage the brain nerves of teenagers, leading to headaches, memory loss and sleep disorders. Playing mobile games often may also make children deaf, and if it reaches 85 decibels, their hearing may be impaired.

5, causing security problems, because there are many mobile phone brands, the quality is mixed, it is difficult for consumers to distinguish, plus improper use (use in thunderstorms, playing video games for a long time, etc.). ), cell phone explosions sometimes hurt people. In some places, criminals take advantage of students' weak awareness of prevention and resistance to rob students of their mobile phones. On the afternoon of April 22nd, 2005, Lei Zhu, a senior two student in Xiangtan County, was walking on campus. She died on the spot after being struck by sudden lightning. Later, after forensic identification, the lightning strike was caused by the PHS that Lei Zhu carried with him. In July, 2004, a california gurls, aged 16, suddenly exploded in his clothes pocket, causing serious consequences of second-degree burns. (China Economic Times, July 29, 2004)
