The harm of writing 300-word mobile phone

With the development of science, people's lives have made great progress, but those high technologies in life will also bring us harm. Cell phones, I think everyone knows. Mobile phones bring convenience to people's lives, but everything has advantages and disadvantages, and the harm brought by mobile phones even exceeds that of smoking. When people use mobile phones, they will send radio waves to the transmitting base station, and the human body will absorb these radio waves more or less. These radio waves are the radiation of mobile phones.

Generally speaking, mobile phones radiate less when they are in standby and more when they are talking. When the mobile phone number is dialed but not connected, the radiation is the largest, and the radiation amount is about three times that of standby. These radiations may change human tissues and adversely affect human health. Moreover, according to the Oriental Daily, a German study found for the first time that mobile phones may cause eye cancer, because researchers found that people who frequently use mobile phones are three times more likely to develop eye cancer than others. If this research result is further confirmed, it will inevitably lead to a large number of claims litigation.

The radiation released by mobile phones has long been accused of temporarily changing the function of brain cells, but there has been no evidence that these radiation will harm human health for a long time.

However, this study, led by Professor Shi Tangshou of the University of Essen in Germany, made an amazing discovery. When they investigated the eye cancer of uveal melanoma, they found that this kind of cancer was closely related to radiation. Mobile phone is an invisible killer, which has brought harm to people unconsciously, but now people can't live without it, so don't ignore its harm.

3. The harm of playing mobile phone to people is mainly written in 500 words: "Hey, did you hear that?" I waved under Xia Jie staring at the mobile phone screen. She came to her senses, looked at me with confused eyes and popped out a sentence: "What did you just say?" I was furious, but I was helpless.

Today is New Year's Eve, and Xia Zi and I are sent out to buy new year's goods. I looked at the list of new year's goods written by my sisters along the way, and discussed with Xia Zi where to buy cheaper things. But every time she talks about a place, she just, uh-huh, oh, the thief's bright little eyes never shift from staring at the mobile phone screen, and her fingers quickly press various characters. I really doubt that her genius was taken away by those so-called "bosom friends".

We walked to a shopping mall on Renmin Road. I turned to Xia Zi and said, "You wait here, I'll go in and buy, and you can help me with my things when I come out." Oh, there she is again, her eyes and fingers are still dragging upstream of the mobile phone screen. An hour and a half later, when I finished shopping and wanted Xia Zi to help me divide it, she casually said, "You are strong, you can take it yourself. Can't you see I'm busy? " I had to carry a lot of things and go forward in a sulk. I looked around and found that most post-8090 s people were as hurried as Xia Zi. Eyes covered with red blood and fingers frozen into popsicles only focus on the mobile phone in front of me. The original straight back was bent into an arc, like a hunchbacked old man, without vitality. On the contrary, it is just a continuous button.

Going home on annual leave, I saw my sister who came to pick me up at the bus station. I thought I could have a good talk with her, but the result was disappointing-she is also a "low-headed family". I sighed in my mind. Now, in the classroom, on the street, on the bus and on the road, groups of young people pass by us in a hurry. They all stare at the screen of their mobile phones with their heads down and their fingers slide quickly. They have been immersed in the world of Internet and mobile phones for a long time, and they only talk about QQ, Weibo and WeChat ... They never tire of it, completely ignoring the people around them and even ignoring what happened to them. They know and care about the world of mobile phones and networks, but they know nothing about the affairs of the surrounding social countries. In this way, their bodies will not only collapse, but also their beliefs will collapse!

All young people who are addicted to mobile phones and the online world, please look up and go your own way confidently and calmly!

4. What is the most popular 300-word composition for smart phones today? Buy a smart phone, of course. What's special about it? It is estimated that most people will answer: fun! However, do you know its harm to people?

First of all, talk about its price. This kind of mobile phone is usually around seven or eight thousand yuan, but now the price has gone up, and some smart phones may be around ten thousand yuan. This price often poses a great threat to people who are not rich but want this kind of mobile phone, forcing them to "go bankrupt."

Let's talk about its harm to the family first. Because children nowadays are "overindulgent", there are many phenomena of "smashing fat". Some children will show off to their peers with a smart phone: "Look, I have such a fashionable mobile phone, how rich our family is, and you don't even have such a mobile phone, envy you, poor man!" Those children who listen are often envious on the surface, but they are not convinced psychologically. They will think: What's the big deal with having such a mobile phone? Look, I will bring a "luxury" mobile phone next time! Therefore, they will ask their parents to buy themselves a smart phone. Because of doting, parents will buy them such mobile phones, thus "losing everything" and becoming beggars.

Then talk about its harm to children. According to related reports, in recent years, children's myopia rate is increasing and their physique is declining. What's going on here? Smart phones, of course! Because children often like games on their mobile phones, they will play them when they do their homework and in class. Some children even hide their smartphones under the covers because they can't sleep. This, of course, led to the injury of children's eyes caused by the strong light of mobile phones, and also led to the failure of children to complete their homework because of playing mobile games, and their grades plummeted. Because I have been playing mobile games for a long time, I am punished for not exercising too much, which leads to obesity. Running a few steps will make you angry, leading to physical decline and various diseases.

Finally, talk about its harm to human body. As we all know, electronic products have radiation, and mobile phones are no exception. Moreover, the radiation protection ability of children's skulls is not as strong as that of adults, and radiation naturally enters the brain easily. This leads to various intractable diseases such as memory loss and dementia. Friends, is this what you want?

Having said that, everyone knows the harm of smart phones, and it may not be so good. However, as long as we make good use of it and are not stubborn, its harm can also be lost by us. Nothing is perfect!

Professor Yao Ke, director of the Institute of Ophthalmology of Zhejiang University, has proved through years of experiments that the mobile phone should be put in a purse and turned into a portable mobile phone. For example, if there is no stranger, don't put it on the pillow. Because few people used mobile phones at that time, experts thought that the harm of mobile phones would be more serious than smoking.

7. How harmful is the mobile phone? Think in 500 words. Everyone wants to be healthy, but the radiation of mobile phones is very harmful to people's health.

In daily life, everyone is using mobile phones, and some people put their mobile phones on clothes, which will radiate to their hearts.

Dr. Dipa, director of Georgetown University Cancer Center, said: "Our latest research, combined with previous studies, shows that mobile phones increase the potential risk of brain tumors." "Coincidentally, medical experts from the University Hospital in ? rebru, Sweden, also released the research results, saying that after analyzing the global related research of 1 1, they found that using mobile phones 1 hour every day would increase the risk of brain tumors in the long run.

* * * thought, this time the phone dial out radiation is the biggest. When sleeping at night, the mobile phone is placed on the bedside, which is radiation to people. When using headphones, use hands-free headphones to answer, and don't let the phone close to your ear for 5 seconds before the call is connected. Dr. tolga Artet of Suleiman University and his colleagues found that the electromagnetic field of mobile phones may reduce bone density and lead to osteoporosis.

Don't carry your mobile phone with you. It's best to put it in your bag as far away from your body as possible. Don't pin the mobile phone on your waist to prevent the microwave from harming human internal organs.

In order to prevent the radiation of mobile phones, I think we should do the following: First, put radiation protection stickers on mobile phones. Second, stay away from mobile phones and try not to take them with you when you don't need them. Third, don't get too close when answering the phone. Otherwise you will be exposed to radiation.

The main function of a mobile phone is to make and receive calls.

Now, the technology is gradually developed. People have gradually integrated into society, but their eyes are getting closer and closer, and their awareness of eye protection is gradually fading. The radiation of mobile phones to people is low and high. The original mobile phone has no radiation, which is much better than the current mobile phone.

If you answer the phone for more than 1 hour, the radiation will be more severe. It is best not to play mobile phones for more than 1 hour, because it will cause radiation to the eyes. Almost all students and adults wear glasses now, which may be related to using your mobile phone for a long time.

If the mobile phone is close to the heart, it will also radiate the heart, which will have a bad impact on people's health.

8. The danger of urgent mobile phones When it comes to mobile phones, no one is unfamiliar, even a three-year-old child 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.

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?

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.
