In addition to using \"hands-free\" devices, which keep mobile phones away from the head and body during phone calls, exposure is also reduced by limiting the number and length of calls. Using the phone in areas of good reception also decreases exposure as it allows the phone to transmit at reduced power. The use of commercial devices for reducing radiofrequency field exposure has not been shown to be effective.

A large number of studies have been performed over the last two decades to assess whether mobile phones pose a potential health risk. To date, no adverse health effects have been established as being caused by mobile phone use.
Tissue heating is the principal mechanism of interaction between radiofrequency energy and the human body. At the frequencies used by mobile phones, most of the energy is absorbed by the skin and other superficial tissues, resulting in negligible temperature rise in the brain or any other organs of the body.
Epidemiological research examining potential long-term risks from radiofrequency exposure has mostly looked for an association between brain tumours and mobile phone use. However, because many cancers are not detectable until many years after the interactions that led to the tumour, and since mobile phones were not widely used until the early 1990s, epidemiological studies at present can only assess those cancers that become evident within shorter time periods. However, results of animal studies consistently show no increased cancer risk for long-term exposure to radiofrequency fields.
Several large multinational epidemiological studies have been completed or are ongoing, including case-control studies and prospective cohort studies examining a number of health endpoints in adults. The largest retrospective case-control study to date on adults, Interphone, coordinated by the International Agency for Research on Cancer (IARC), was designed to determine whether there are links between use of mobile phones and head and neck cancers in adults.
While an increased risk of brain tumors is not established, the increasing use of mobile phones and the lack of data for mobile phone use over time periods longer than 15 years warrant further research of mobile phone use and brain cancer risk. In particular, with the recent popularity of mobile phone use among younger people, and therefore a potentially longer lifetime of exposure, WHO has promoted further research on this group. Several studies investigating potential health effects in children and adolescents are underway.
In response to public and governmental concern, WHO established the International Electromagnetic Fields (EMF) Project in 1996 to assess the scientific evidence of possible adverse health effects from electromagnetic fields. WHO will conduct a formal risk assessment of all studied health outcomes from radiofrequency fields exposure by 2016. In addition, and as noted above, the International Agency for Research on Cancer (IARC), a WHO specialized agency, has reviewed the carcinogenic potential of radiofrequency fields, as from mobile phones in May 2011.
WHO develops public information materials and promotes dialogue among scientists, governments, industry and the public to raise the level of understanding about potential adverse health risks of mobile phones.

Essay on Disadvantage of Mobile Phones: In the modern world of science and technology, we all face different problems while using technologies. The mobile phone is a product of science which has become very important for us. Thus most of us use mobile phones like these are our friends, and that causes various problems. There are so many disadvantages of using mobile phones. Constant distraction, social disruption, never-ending workdays, ongoing expenses, cause of accidents, health problems, youth crimes, etc. are some of the major disadvantages of using mobile phones.
Mobile phones leave negative impacts on personal contacts. We have seen many teenagers having dinner with their family members. But instead of joining in conversations with them, they keep themselves busy on their mobile phones scrolling through news feeds on social media applications. In this way, many people have lost their conversation skills which restrict them from interacting with other people. Using cell phones can cause distance in relationships too.
There are so many people in this world who use mobiles phones as fashion. They upgrade the models of mobile phones they use regularly. Mobile phones are costly nowadays, and buying new models in a certain interval of time will make you spend too much money.
Mobile phones contain so many private photos and videos. Maintaining the privacy of these photos and videos have become harder these days as the mobile manufacturing companies and applications installed in the phones can go through your things in your phones. Hackers can easily hack your mobile, and the private things in your phone can be easily stolen.
When we use mobile phones constantly, we get addicted to mobiles phones. Addiction to mobile phones can cause various mental disorders to human bodies. Isolation in the people is caused due to excessive usage of mobile phones.
Mobile phones are one of the main reasons behind the wastage of our valuable times. Mostly the students of school, colleges and teenagers are affected by wastage of time due to over usage of mobile phones. They spend too much time using mobile phones for playing video games, chatting, watching movies, and thus they waste their precious time.
1. Mobile phones cause isolation in people. 2. Excessive usage of mobile phones causes wastage of valuable time. 3. Addiction to mobile phones causes distraction from works. 4. Wastage of too much money is also caused due to mobile phones. 5. Mobile phones cause cyberbullying. 6. There are many security issues in mobile phones that can leak the private info and photos or videos on the phone. 7. People lose time for their study due to overusing mobile phones. 8. Distance from relatives and family members is one of the few negative impacts of mobile phones. 9. Mobile phones cause various health problems and sleeping issues, 10. Cell phones are one of the main reasons for road accidents.
By India Today Web Desk: With the advent of advanced technology, growing use of mobile phones and other gadgets are considerably harming the younger generation. Students are developing a strong connection with their mobile phones, which is leading to a massive loss in their concentration and time spent in studies. Parents and teachers usually face problem in combating the distraction of students.
According to a report published in the Guardian, a research done by Louis-Philippe Beland and Richard Murphy, published by the Centre for Economic Performance at the London School of Economics, says: "Ill Communication: The Impact of Mobile Phones on Student Performance" found that after schools banned mobile phones, the test scores of students aged 16 improved by 6.4%. The economists reckon that this is the "equivalent of adding five days to the school year". 2ff7e9595c
