Are cell Phones a Health Hazard?

Are cadre Ph cardinals a health Hazard? With the increasing of officious head prognosticates functions, pile rely much and more on them. The lower price in addition enables the diligent call back to run good deals fooling necessity. Now even many students pass water their aver unsettled phone. People began to worry or so the cadre phone which leave behind do harm to our health. But why nation become worried about that? There atomic number 18 some speculates that carrellular phone phone might emfly threaten man beings health. Mobile phones potbelly emit radiofrequency cipher (radio waves), which is comprise by non-ionizing radiation.Things c escapest to the carrel phones volition absorb this energy. According to the cellular Telecommunications and Internet Association, as of 2010, there were more than 303 million subscribers to mobile phone service in the United States, which is closely three measures than the one hundred ten million workrs in 2000. Globally, the number of mobile phone subscriptions is estimated to be 5 billion by the International Telecommunications Union. The number of mobile subscriptions has already increase quickly.(Cell Phones and crab louse Risk, 2012)The chart below (Chart 1) shows the number of mobile Internet users, including the forecasting of the number in 2013. Over time, the amount of time of each phone call, as well as the number of pile using the mobile phone has increased. Mobile phone technology has besides had a actually big change. Chart 1 Chart1 US moblie Internet users & penertration, 2008-2013 (millions and % mobile phone subscriers) To my instruction of thinking, cell phones provide really see a health post. RF is a potential threat to human be.Radiofrequency energy (RF) is a form of electromagnetic radiation. Electromagnetic radiation rouse be defined into two types ionizing (e. g. , x-rays, radon, and cosmic rays) and non-ionizing (e. g. , radiofrequency and extremely lo w-frequency or power frequency). (Cell Phones and Cancer Risk, 2012) As we know, all of the creatures and plants, including humans, ar exposed to ionizing radiation and non-ionizing radiation during the totally period of evolution. So youthly the society began to worry about the potential harm of RF from cell phones which whitethorn cause mindset can buoycer.A serial publication of studies began to get word at the relationship between cell phone employment and brain tumors. If cell phone will bring a detrimental effect was a controversial topic, and the opinions on this topic be extremely different. Some mess hold that cell phones atomic number 18 nothing to do with the health riddles, since the non-ionizing radiation from cell phones is typically unattackable to the human body. A low direct of radiofrequency energy is a kind of non-ionizing radiation, and it is different from amply levels of radiofrequency energy that produces negative health effects by heating tis sue.(Radiation-Emitting Products, 2012) Therefore, it can say people exposed to low level RF which does not heat tissues in human body are not obligatory to worry about with cell phones. Although low level RF is safe doesnt mean that the potential damages do not exist. Firstly, our brain is able to absorb the electromagnetic radiation at radio frequencies that emitted by mobile phones, so if we use mobile phones for a long time, which will increase the hazard of brain cancer to a great extent. So this is a long-term effect. Secondly, cell phones are becoming more advanced, and the interior structure of cell phones has had a great change.Cell phones obligate come to our daily life with more functions, which may have unknown effects. A recent study showed that when people employ a cell phone for 50 minutes, brain tissues on the same side of the head metabolized more glucose than that on the opposite side of the brain. (Cell Phones and Cancer Risk, 2012) It means that using cell ph ones can change some tissues of human body, although the outcomes have not been deemed good or not. Another negative effect is that public lecture through cell phones when drive will increase the risk of traffic accidents.There were nearly 80 million people who own cell phones, and surveys indicated that 85 percent of these owners use phones objet dart driving. (Williams & Analyst, 2002) According to the journals publisher, the Human Factors and Ergonomics Society, there are 2,600 deaths and 330,000 injuries in the United States e real year because of mobile phone distraction. (Britt, 2005) Drivers talking on cell phones will have their attention distracted. As a event of fact that only 80% of their attention can be compensable when they are talking to somebody. And speaking requires more attention than listening.In a conversation, if a driver is more eager to talk to others than to listen, the greater the distraction he has. It is said that drivers use cell phones when they are driving just look exclusively dont see. There were two different experiments associated with prof of psychology Dr. Amit Almor. (Science Daily, 2008) One experiment contracted the participants to test the visual do work on a monitor, and the second experiment required participants to do a visual task sequence listening to a story that had been prerecord and then the participants were required to tell their feeling about this story.In the end, the attention level of these participants had been measured. People found that they were four times more distracted when people were speaking than when they were listening. It came to a conclusion that speaking demands more brains resources than listening. People are apply to communicating face-to- face, so if they were talking while driving, they will imagine the conversation in their brain, and they have to try to conceive what they have been talking and how to respond in a dear position. perceive loss is also a big health hazard .People who use cell phones for more than one year acquire audience loss problems, consort to research presented at the American Academy of Otolaryngology-Head and Neck Surgery Foundations one-year Meeting & OTO EXPO in Washington, DC. Otherwise, the study found that people who employ mobile phones more than one hour a twenty-four hours were more likely to suffer from hearing problems. (Robert, 2007) Obviously, long-term use of cell phones will have a great impact on hearing, which is in general a negative impact. Using cell phones too long may damage our inner ear and bring about a graduate(prenominal) frequency hearing loss.High frequency hearing loss means that people may feel difficult to hear consonants such as s, f, t, and z, exclusively they can hear vowels generally. Therefore, although people can hear muffled sounds, they inefficient to figure out what people exactly say. Not just talking too much through cell phones may cause hearing loss, but listening to hig h-pitched decibel medicament is also producing a big damage to hearing. People now would like listening music with their phones wherever they go, such as in the train, because it is very noisy when victorious a train, so people ever prefer listening to high decibel music that they can enjoy the clearer music.If some symptoms such as ear ringing, ear warmth, and the ear fullness have arose, which are sample signs that your hearing is in danger. What are the reasons these symptoms have occurred. The possible cause is the electric-magnetic-frequencies, which emit a magnetic field greater than 3 milli-gauss from many cell phones.The Environmental Protection Agency has announced that electric-magnetic-frequencies greater than 3 milli-gauss may do harm to human health. (Robert, 2007) Naresh K. Panda, MS, DNB, chairman of the department of ear, nose, and throat at the Post Graduate Institute ofMedical Education and Research in Chandigarh, India, and researcher for a study. He and his c olleagues performed experiment. They texted 100 people, at the age of 18 to 45, who had used cell phones for at least one year, and according to aloofness of use, they divided this people into 3 groups. One group had 35 people, who had used cell phones for one to two eld, and another group of 35 had used cell phones for two to four years, and the final 30 people had used them for more than four years.Those who used the mobile phones for more than four years suffered a greater degree of hearing loss in their right ear, the ear a lot listens through the phone, than those who used the mobile phone for one to two years. (Doheny, 2007) As well, using cell phones too long will hurt our lookight. Numbers of people use cell phones every twenty-four hour period. We can do many things on our cell phones sending text messages, discipline emails, surfing the web, and even finding the driving directions. Its so tremendous that we can do all of this work just in a device which can be held in one hand.However, lots of problems are coming with this convenience. Reading such the really small text on the phones will cause problems. Not only for the tiny letters in such a small screen, but also people have become accustomed to holding the phone closer to their face than they need to. Reading from your phone forces your eyes to focus in a way which is much different than before when people usually read from paper. It is also harmful with your eyes vergence, which is the simultaneous movement of both eyes in opposite directions to obtain or maintain single binocular vision.Although your eyes are designed to adapt to the circumstances more easily, many people have become accustomed to recital from their cell phones all day long. In the long term, not only can this habit lead to troubles, but also eyestrain, dry eyes, and blurred vision. According to Dr. Jeffrey Hankin, an optometrist, people are pulling their smart phone four inches closer than normal reading distance coul d cause problems. (NBC25 News, 2011) This is always accompanied by a headache while people just feel tired and maybe have a little difficulty on focusing.Sometimes the blink rate will slow down and the eyes are dry. These symptoms cannot be ignored. It is saying that your beholding is becoming weaker. How cell phones damage our eyesight? We are in the surroundings full of radiation and electrical signals , at the same time, human body was being attacked by hundreds of signals every second. It is affecting all our body parts, but we have not aware of it yet. The wavelength of wireless signals (which is about 2 to 2. 5 cm) used for mobile phones and other wireless terminals matches with that received by the human eye.The dielectric constant (absorption capacity) of eye tissues is around 70 which is greater than bingle (above 50). This means that the eye can absorb electromagnetic energy very quickly, explains Dwivedi. (Cell phones can damage eyes, 2010) So it comes out a conclusion that the problem is not the energy absorbs by the eye, but the heat from the energy draped by the eye cannot get transmitted out of the body. Moreover, cell phones have a strong relationship with human mental health. People always take cell phone with them all the time, no matter where they go.They assume games, listen to music, watch videos, and chat with friends. It seems like that we cant live without cell phones, particularly children. More and more children at 12 and 13 ages have their own cell phones. Those children who are addicted to cell phones spend most of time on their phones, like talking, texting or playing games. Their parents are beginning to be concerned that the children are unable to do some normal activities without their phones. They often skip classes and lie to relatives to get more money to buy phone cards.It these situations, cell phones are just like the drugs which make the children gradually lose themselves. Whats more, lots of students even play cell phones during class. While teachers are speaking in front of students, students are texting or playing games in their seat even without any covers. The other mental problem is that cell phone is tending to cause depression and sleep problems in young people now. Young people who use cell phones heavily also complain more about sleeping problems, pressures and other mental health problems, according to researchers at the University of Gothenburg, Sweden.(Pedersen, 2012) Researchers made a questionnaire survey towards 4,100 young adults at the ages of 20 to24 and interviewed 32 heavy users of information and communication technology. The findings interpret that the use of mobile phone has a close relationship with pressure, depressive symptoms and sleeping disorders. The researchers could not be sure of the origin causes, but what we can speculate is that people with depression or sleep problems perhaps get access to cell phones more than others. Here is more other evidence. The Univ ersity of Tokyos researchers investigated nearly 18,000 young people in in high school in Japan.In order to estimate their depression, anxiety and even thoughts about suicide, the participants were required to firmness of purpose some specific questions. Participants also reported how often they spoke on their cellphones or sent emails after going to bed and how many hours they slept at night. The findings tell us that children in different countries with different cultures have mistakable problems are related to similar reasons. As a whole, cell phones are closely integrated cell phones into our lives, yet they have health hazard for our daily lives. We should use them in a proper way.
