How much do you know about the dangers of mobile phones?

Currently, China's mobile phone ownership has surpassed that of the United States, reaching more than 1 billion units. However, Chinese people who love mobile phones so much do not have enough understanding of the health risks that mobile phones can bring to them.

Mobile phone radiation: scarier than imagined

A British experimental report pointed out that mice exposed to microwave radiation from mobile phones for 5 minutes will develop DNA lesions; humans who are exposed to microwave radiation from mobile phones for a long time will also develop DNA lesions.

"Radiation is equivalent to cooking the brain." British scholars once conducted an experiment and put a mobile phone in a nematode breeding box. After a period of time, they found that the electromagnetic radiation emitted by the mobile phone acted as if the nematodes had been boiled in water. The penetrating power of electromagnetic radiation is very strong. After the microwave penetrates the skull, it acts on the brain, which is equivalent to cooking the brain. Relevant studies have confirmed that when using mobile phones, 40% to 60% of the radiation directly penetrates into the brain to a depth of one inch to one and a half inches, and the radiation from mobile phones will continue to accumulate in the brain. Microwaves have strong heating capabilities, and microwaves have strong penetrating capabilities.

The microwave weapons being developed by the U.S. and British armies can raise a person's body surface temperature to extremely high levels within 2 seconds, and can "scorch" the enemy almost instantly, taking advantage of the heating effect of microwaves. The mobile phone is close to the human body (especially the head and eyes), and the microwave radiation is strong and highly concentrated. It will quickly penetrate the skin and skull and enter the brain, heating the brain. In human tissues containing rich blood vessels, microwave radiation can increase the temperature to 42-44 degrees. Repeated heating of human organs activates the body's heat shock proteins, and these heat shock proteins can destroy the cell's defense system and cause cancer.

the data shows:

According to a sample survey of middle school students in a middle school in Zhejiang, 53% of junior high school students own mobile phones, and 87% of high school students own mobile phones. This worries Chinese educators.

Reasons why parents agree:

①Easy to contact yourself 80%

②Communicate better with children 15%

Reasons for disagreement:

①Used for falling in love 47%

②Afraid of children attending class, texting, playing games, etc. 19%

③Afraid that children will receive unhealthy text messages 34%

Teacher’s attitude:

Disagree/There is no need to bring mobile phones back to school

(Considering the need for phone calls at school, IC cards and 200 cards can replace mobile phones)

①School regulations

②Class is affected

The harm of mobile phones to students

Chatting via text messages affects rest and delays studies.

In the past, students had to climb over school walls to go to Internet cafes to access the Internet. Now, students can chat on QQ and browse bad websites directly on their mobile phones at any time in the classroom. When students read novels and chat all day long, where do they have the energy and time to study? At present, mobile phones have become the main source of mental pollution for students. While bringing huge profits to the communication sector, they also have great side effects on students’ mental health. The consequences are very serious. No wonder primary and secondary schools in the United States are Students are prohibited from wearing mobile phones.

Encourage students to become more competitive.

Some middle school students today are simply blood suckers on their parents, and there are always many middle school students pestering their parents to buy them. It encourages children’s comparison mentality.

Mobile phones provide conditions for cheating in exams.

After students have mobile phones, some students spend most of their time and energy playing with them, and are unable to do anything when it comes to exams. Except for the college entrance examination, they basically rely on their mobile phones to cheat and get through exams. This kind of examination style will make the school's style of study deteriorate from bad to worse. A vicious cycle is formed.

What are the pros and cons of using a mobile phone?

1. Frequent use of the machine is harmful to the body and mind.

Mobile phones mainly implement their functions through radio waves. The radio waves transmitted by mobile phones are more or less absorbed by the human body, which may change human tissue. Scientists are deeply concerned about the radiation from mobile phones and have clearly pointed out that frequent and prolonged use of mobile phones will have a certain impact on human health. This effect is mainly manifested in memory loss, sleep disorder, psychological irritability, headache, etc. Middle school students are in the growth and development period, and many body functions are not yet perfect. Mobile phone radiation harms students' development and affects their health, causing a significant decline in understanding, reaction, and memory, hearing damage, and immune dysfunction.

2. Cheating in exams, impacting exam style and study style

During academic performance testing, some students use their mobile phones to cheat, deceive parents and teachers. As a result, energy in class is dispersed, study is not done diligently, the classroom is disturbed, and the teaching order is seriously affected. Especially as a student, you will inevitably not study hard and your academic performance will decline. Some students also use text messages to tease teachers and classmates, which affects the formation of students' good qualities.

3. The proliferation of yellow is not conducive to adult development.

Mobile Internet access, QQ chat, online games, e-books and other functions, as well as bad text messages, mobile phone pornography, gambling, and drugs, poison young people. Pornographic information, pornographic websites, etc. are very harmful to young students who are not deeply involved in the world. They have a strong sense of curiosity and seriously affect the healthy growth and development of young students. Because some students are affected by unhealthy content, their moods fluctuate greatly, they lose concentration, and their academic performance plummets. Some students violate disciplines and laws and eventually turn to crime

4. Breaking school discipline and affecting teaching and learning

Students use mobile phones to hide in bed at night to send and receive text messages, read novels, play games, and stay up late at night. Mobile phones have become entertainment products, interfering with other people's rest, and reducing learning efficiency. Students generally carry their mobile phones with them. In the classroom, some students' mobile phones are turned off, and most of them are on silent or vibrate. Some students receive five or six text messages in a row during one class and cannot listen to the class with peace of mind. There are also some who forget that the mobile phone rings during class, disrupting the teaching order, affecting the efficiency of listening to the class, and despising the teacher's work. The teacher is disgusted, and the students who love learning are extremely disgusted.

Stay away from mobile phones

strongly demand:

(1) In middle school, students should focus on their studies, and students with weak self-control should avoid interference from external factors. If you have a mobile phone, hurry up and take it home; if you don’t have it but have this idea, cancel it immediately!

(2) Use a public phone!

(3) Middle school students are strictly prohibited from carrying mobile phones on campus. Once discovered, they will be dealt with seriously.

Red flag: Confiscate it if you see it.

Wu Dan hits the mark: throw it down when you see it.

school advice

1. In middle school, students should focus on their studies, and students with weak self-control should avoid interference from external factors.

2. Students should be considerate of their parents and never blindly ask their parents to buy them mobile phones, which would increase the burden on their parents.

School attitude:

1. Students are not allowed to bring mobile phones back to school for any reason;

2. Once students are found playing with their mobile phones, the class teacher will take care of the mobile phones until the end of the winter and summer vacations and return them as appropriate, or notify parents to come to school to apply for them back; more serious cases, the whole school will notify the whole school of criticism and record a major demerit.

3. If any suspected mobile phone light is found in the dormitory during the late sleep period, 5 points will be deducted for each person in the grade group score;

4. If anyone is found to have brought a mobile phone into the examination room during the examination, the result of the subject will be zero and the whole school will be notified and criticized;

5. Students who often make mistakes due to mobile phone problems and do not repent after repeated education will be ordered to drop out of school or directly expelled from the school.

Conclusion:

Thinking about the busy parents, for the sake of our own future, let us join hands to advocate a ban on the use of mobile phones on campus and create a healthy and harmonious campus!

Please let your phone go home!
