Do you know the negtive effects of using the cell phones?
There are three main disadvantages of using cell phones.First, you cannot contract with others every minute because someone doesn't take cell phone with him all the time ,or their phones are often in the state of vibrancy that they themselves cannot hear the phone ring or aware that they exactly have a cell phone, if you have something urgent to tell him or her ,there must have a delay to extent.

Second ,if your boss or teacher is talking something important just at that moment, your phone rings, which maybe let you be embarrassed because you attract all others' attention .
Third, there are potantial health risks exist .When we use cell phone ,we put it near our ear,and the antennaof the cell phone produce radio signal radiation ,our brain is somewhat protected by the fixed skull made of bones, but the radiation can through from our ear.The radiation may cause brain cancer or other cancers.This issue was said by a man in Florida of America ,he said his wife had been diagnosed had brain cancer which caused by her cell phone ,he then took legal action , but the court dismissed the legal action because of lack of scitific and medical evience.But later on ,there were more and more lagal actions appeares on the media and the courts, so health risks caued by cell phone became a public concern .Then wireless communication technology industry established a special group consisted of experts to take a research on whether it is safe to use cell phone,but tthey found there is little link to radiation and cancer after a series of experiments.After that ,a study in Sweden showed that the person who use cell phone were two and a half ttimes is likely to suffer brain tumor near the ear they hear the phone . pPkvP+W
So ,if you have something helpful to avoid or reduce the bad effects of cell phone ,please tell us! I have found some ways to protect ourselves from the signal radiation of mobile phones.Firstly, stay at a relatively fixed place when you make a phone call .Secondly, you could change your ears to hear the phone ,not just one ear close to the phone .Thirdly, you should wait for several seconds before answering the phone and so does when you make a phone call .Fourthly, when you get asleep , you should turn off your mobile phone,and put it far from your body ,especially your head. Fifthly, you mustn't use mobile phone in the thundering and raining day .All above are some good advice , which I got from a magzine ,I hope these advice will help the persons who read my writing . good topic, we should protect ourselves from the cellphone i always know that. so i avoid speaking direction to the phone now. try to use earphone. and send txt. mobile phone ----> brain damage::z8 It is true that using mobile phone is no good to our body, especially our brain ,but it cannot deny that this little thing exactly bring us great convenience ,I think you can use e-mail or QQ to contace with your family and friends,or even you can write a lettler,maybe this is an old-dated way ,but your feeling to receive a letter from someone is very different from that when you hear a phonecall or receive an e-mail and chat in QQ ,especially between lovers,it is romantic! Some people often stand at a narrow corner when they make a phonecall ,actually it is not right .We should stand in a spacious place and the electrical signals there are much better than that in the narrow corners. And , the signal will change with our position ,that is to say ,if we are moving when we are talking on the phone ,the direction and strengh of the signal will change ,then the ability of our mobile phones to receive the signal is affacted , and then the magnetic field formed by our phones will make something bad to our brains.This is the theory of the bad effects caused by mobile phones ,which I get from a magzine ,some professional words I cannot express ,just know its basic points ,I hope you can understand me ! I've heard of that, but for the damage can't be seen right away, so sometimes it is so easy to forget the harmness thx, earphone is a good advice I am sorry that my mobile phone is not an earphone companied,so I cannot use the earphone ,but to me , not a busy girl, there is not so much call ,so it is an indirect way to avoid me to contact the radiation for a long time !Oh ,thank goodness!
