Refutation of the harm of mobile phone to middle school students in debate competition

Scientific research also shows that children's early and long-term use of mobile phones may lead to mobile phone dependence and bring many physical and mental damages.

1, the potential harm to children's brain nerves is more serious. Research in the British magazine Microwave Theory and Technology shows that the skull thickness of children is obviously lower than that of adults, and the absorption rate of radiation is obviously higher than that of adults. Professor Zhao Yufeng, from the Indoor Environment Monitoring Committee of China Interior Decoration Association, told the reporter of Life Times that children's nervous system is in the development stage and the potential threat is even greater. A test by clermont-ferrand University shows that when children use mobile phones, their brains absorb 60% more electromagnetic waves than adults. Recently, the British "Daily Mail" even wrote that children's use of mobile phones can cause health problems such as memory loss and sleep disorders. Dr. Gerard Kaidu of the University of Warwick in the United Kingdom warned that cell phone radiation would destroy the normal function of children's nervous system, which would lead to a series of problems such as memory loss, headache and poor sleep.

2. It has serious adverse effects on children's growth and development. Du Junbao, deputy chief physician of Pediatrics Department of Peking University First Hospital, said that high-dose electromagnetism is not only bad for children's growth and development, but also brings diseases such as asthma and leukemia. Ren Yixun, a neonatal expert at Beijing Children's Hospital, said that children are in the stage of growth and development, and the water content of body tissues is richer than that of adults. The more water, the greater the damage to organs. Therefore, microwave is the most harmful to human eyes. Playing games with your head down for a long time is very harmful to your child's cervical spine. In addition, long-term texting can also lead to abnormal finger development in children.

3. Make the child's way of thinking thin. A study by Professor Abu Lamson, an epidemiologist at Monash University in Australia, shows that teenagers who love texting are hard to think deeply, eager for results and more impulsive than their peers. Moreover, children use mobile phones for a long time and lack the opportunity to communicate face to face with others, which easily makes them timid, withdrawn and paranoid. Using the associative input function of mobile phone to send text messages will make children only pursue speed and ignore accuracy when doing other things, which will greatly affect their way of thinking.

4, premature use of mobile phones can easily lead to children alienating their parents and indulging in games. Lin Dehua pointed out that sending text messages to classmates and friends often may make children reluctant to tell their parents the truth, and deepen their parents' sense of loss of control and the gap between parents and children. On the other hand, with the development of modern communication technology, mobile phones can surf the Internet anytime and anywhere, which makes it more convenient to download games. Some children may be too addicted to games, which will affect their growth.

5. With the rapid upgrading of mobile phones, letting children use mobile phones too early is likely to make them blindly compare with others.

On the positive side, it may be said that mobile phones bring convenience to people and better understand the latest information in the world.

Opponents can refute: people's health is more important, or convenience is more important. It is also mentioned above that mobile phones will also have problems.
