Mobile phones are really very important in our lives that we cannot think our life without them. It is a long-range, portable electronic device used for mobile communication. Mobile phones are affordable, easy to use and comfortable. They manage our every task in office or in our home. They are not just the communication medium but also the computation medium. They are equipped with the high-end features and specifications that it really makes us feel great in having them in our hands. The mobile phones have become crucial part of our life. There are facts which prove this. They have replaced the wrist watches or our alarm clocks at home as we can see time in them wherever we are and can even know the time of other countries and set according to it. We can also set the alarms in them. A mobile phone gives us a way to communicate with others. We can chat with friends whenever we like. If you are too lazy to dial a number, you can also tell your ‘little secrets’ to your friends by sending a SMS, in other words, Short Message Service. We can also find that some of us keep sending SMS during lessons. There are more functions and features such as listening to music, taking pictures with an in-built camera, playing games, and even logging on the internet, can hold a meeting easily by 3G, video player, using Bluetooth to send a file, and many more. Although mobile phone has many advantages in our lives, there are also disadvantages that come along with the usage of mobile phones.
Firstly, mobile phone radiation does produce biological changes in humans – such as changes in brain temperature and activity as well as blood pressure changes. Studies have shown that exposure to the RF (radio frequency) waves emitted from mobiles can cause slightly raised blood pressure at the time of use, pressure returning to normal when use is stopped (to put this into perspective, our blood pressure changes regularly throughout the day and is even affected by tasks such as speaking), direct brain warming after prolonged use, which disperses as soon as you stop using your phone and causes no harm, mild fatigue after prolonged use, acoustic neuron (benign tumors of the acoustic nerve) are twice as common in mobile phone users than in those who do not use mobiles. The electronic and radiant rays are very harmful to our brain and it is also harmful for our ears. The radiation of our mobile phone would affect our health. It may cause mouth cancer if you be on using of mobile phone for more than one to two hours. The ray of mobile phones can boil an egg in 65 minutes. Imagine what it can do with the proteins of your brains when you do long calls. Others accumulating evidence indicate that microwave radiation from mobile phones may cause serious diseases and disturbances in the physiology. This includes an increased cancer risk and genetic damage, disturbed brain function and other effects. There is no evidence that using a mobile phone causes tumors, memory impairment, cancer, brain damage, and fetal damage.
Next, we often find some news about the traffic accident cause by mobile phone. Some careless drivers use the mobile while they are driving and oblivious of the traffic safety. Moreover mobile phone while driving is a distraction that brings risk of road traffic accidents. Several surveys have actually concluded that using a phone behind the wheel is more dangerous than driving whilst under the influence of alcohol and more likely to cause a car accident. An average the reactions of the driver were nearly 50% slower than when driving normally and that even using hands free kit did not completely eliminate the distraction caused by having a telephone conversation whilst driving. There is no doubt that having a mobile phone with you in the car can provide security and help in the case of a breakdown or an emergency but the temptation to answer it if it rings or to reply when a text message arrives should be avoided at all costs. It can be seen, therefore, that the seemingly harmless act of talking on a phone really can put lives at risk.
The last, cyber bullying is another big problem. Cyber bullying is a bullying act using offensive words and behavior via online chatting, emails or SMS text messages. It was showed that the psychological effects of cyber bullying are much severe that face-to-face bullying. This problem now is among teenagers especially the secondary students. The big problem caused by mobile is that some people try to disturb other using fake sim-card or they behave immorality with girls through fake sim-card connection crimes are promoting more through mobile phone. Even though cyber bullying cannot physically hurt you, it can still leave you feeling mentally vulnerable and very upset. You can also feel scared, lonely and stressed and that there’s no way out. Escaping cyber bullying can be very difficult. Because anyone can get access to a mobile phone or the internet almost anywhere, it can be tough for those on the receiving end to avoid it, even in the safety of their own home. To combat the cyber bullying are get help immediately from a trusted parent and stay in control.
There are three steps to safer mobile phone use. Step 1; Buy a mobile phone with a low SAR rating. The SAR rating of a cell phone is a measure of the amount of radiation from the phone that is absorbed into the brain in normal use. The law now requires that all cell phones have their SAR displayed on their packaging. Buying a cell phone with a low SAR rating is a great way to significantly reduce your exposure to cell phone radiation. Step 2: Don’t obstruct your mobile phone’s antenna. Obstructing the antenna of your mobile phone during use will increases the amount of radiation from it that is absorbed into the brain. This is because obstructing the antenna of your phone reduces its efficiency, causing your phone to use more power in order to maintain signal quality, and so to emit more radiation. It may also be that obstructing the antenna of your phone increases the proportion of the radiation from it that you absorb, reflecting some of it off your hand and back into your head. To minimize the risks of mobile phone use, you should, therefore, always hold your phone at its base, causing minimum obstruction to the antenna. Step 3: Use a land-line for long conversations. Most of the safety concerns associated with cell phone use relate to the way that the radiation emitted by cell phones in normal use heats the brain. These concerns increase as exposure increases. For safest use, you can therefore restrict your use of cell phones to shorter conversations; if you’re going to talk to someone for hours, then wait until you get home. If you really want to use your cell phone for long conversations, then consider buying a Hands Free Kit in order to reduce your exposure to radiation.
In conclusion, although there are disadvantages of using mobile phones, the advantages of using mobile phones are more. They have completely intruded in our lives and have made their own unique stand. Once it is considered as luxury is now the thing closest to our hearts. I hope you can weigh the advantages and disadvantages of mobile phone and use your mobile carefully and properly. Try to solve the problem by don’t put the mobile phone in your pocket, don’t use the mobile phone more than 15 minutes and be wisely when you buy a mobile phone.
