essay on demerits cell phone
Answers
Answer:
First, negative health effects of using mobile phone have been proved by many studies. From the studies, mobile phone can emit microwave radiation that is detrimental to health. In fact, many reports on the health risks of cell phones have been published over the last few decades. A study led by Dr Agarwal, gives the consequences of the microwave radiation when you use cell phone. First, electromagnetic waves alter electric activity of the brain and cause disturbance in sleep; cause difficulty in concentration, fatigue, and headache; and increase reaction time in a time-dependent manner.

Plz mark me as brainliest.
Many people own a mobile phone these days, and ever since they have been around scientists question the fact of they are safe or not. Do they cause tumors, earaches, mercury poisoning? All these health risks are mentioned in every article I found. But nowhere could I find anything that was sure if mobiles did cause all of the above. This is where science fails us. The problem is that mobile phones are still too new to know the long-term effects on human. Mobile phones give of a radiation of radio frequency round 10 MHZ to 300 GHz. But so do other appliances. Why does mobiles especially get put in the picture of being hazardous? Soon it will be clear whether the radio frequency emissions from mobiles cause health effect.
Drivers who use there mobiles while driving are the only” health risk” that can be proven, the drivers get distracted and lose control over the vehicle. Technology invented something for this, hands-free sets. But now the question is do those hands free sets really solve the problem? Researchers now are looking at if the hands free sets don’t cause other problems. A report from the magazine “which?” said that hands free kits raised levels if radiation to the head from mobile phones by up to three and a half times. The consumer association immediately stressed that it had done no research into this whether this radiation could cause damage to the brain. That just proves that whenever there has been research a report is released to prove that research wrong. Probably is done not to cause any chaos.
Mobiles are said to cause brain tumors, they say this because there was found to be more tumors of the same kind among mobile phone users. Mobiles cause memory loss, radiation sickness. Mobiles can disturb your sleep pattern, according to the researchers from the university of Zurich, mobile phones increases brain activity during our sleep. A really Strange result of the use of mobile phones is that mobile phones can release the poisonous mercury from fillings causing brain damage, scientist say this is due to the electrical fields given off by mobile phones can activate the mercury, giving off a gas. The fumes attach the nervous system causing conditions from depression, asthma to Alzheimer’s disease and multiple sclerosis.
Technology is doing every thing it can to improve the mobile phones. To try and make the radiation that is sent out as harmless as possible, in the mean time before the technological level is high enough to do so, experts have made reports to reduce the amount of radiation. They recommend things like:
Cut down on time spent using the mobile phone
Use a mobile phone where the antenna is mounted outside a car
Keep mobile at a short distance from the ear
Factors that can effect how people perceive how risky new technology is that no one really knows what the long-term effects are, and until that is certain people will still be researching new possibilities. If no immediate link is put between all the risks and the real effect of mobile phones on humans, then there will be no problem in buying mobiles. The problem is that without knowing the really risk manufactures cannot develop mobiles to being safer, so many people are exposed to harmful radiation without that individual knowing. As we know from the past only big helpful research starts when a tragedy hits. In other words, who knows? There is no proof that mobile phones are a health risk, or that they are a hundred per cent safe. Some say the danger does not end until after ten minutes after hanging up because the user is still processing the conversation.

A Mobile Phone
The mobile phone is a latest fight of science to man. It is a wonderful invention. It is actually an improved version of the ground phone. Which was so far considered to be, no doubt, a blessing of science.
A mobile phone is a wonderful instrument which is small only by its size and very big by its functions. You can talk to your friend or anyone you like from your running car or an aero plane, a train or a bus, while on a morning walk in the park or while watching movie in a cinema hall. It has facilitated people in innumerable ways. The businessman uses it to boost his work by being in constant touch with his workers, tremendous response from the public on the international level. Almost all the big cities of the world are connected with even school- going children without a mobile phone. It is a big like accidents or robberies. We can inform the police or any other emergency service .
The mobile phones are improving further. They can be sued now in making use of internet facilities thus giving lots of additional benefits to its users.
