what is harms of using mobile more than 3 hours ?
Answers
Cell phones are one of the few devices that have become an integral part of our daily lives. In fact, they're almost like an extension of us at this point. Almost everyone has one- so much so, that a recent report from the World Bank stated that the world's poorest households are more likely to have access to mobile phones, rather than toilets. While cell phones and smartphones make our life so much easier, there is no denying that the machine does bring some harm, and not only good. Still, don't believe us? Well, here are the top five negative effects from your cell phone to your brain:
1. Cell phone radiation has been classified as a "possible human carcinogen" by the World Health Organization. Yes, this is true! It poses an increased risk of brain cancer from heavy, long-term use.
2. A two-year study conducted by the Radiation and Nuclear Safety Authority in Finland found that brain tissue damage could be caused by radiation from mobile phones.
3. Your cell phone usage could very well give you a tumor! An Italian court recently ruled that a man's heavy mobile phone use caused him to develop a benign brain tumor. He testified that his job required him to use his cell phone for 3-4 hours every day, for 15 years.
4. While your child may constantly beg you for your cell phone to play the latest version of Candy Crush Saga, you might want to tell him no once in a while. Research shows that the bone marrow of a child's head absorbs almost ten times more radiation than an adult's. Yes, you read that right!
5. Our cell phones are powerful enough to accelerate our brain activity, even after just 50 minutes of use. This just goes to show how sensitive our brain is to electromagnetic radiation, and how this could greatly affect us in the long-term.
Well, hopefully, this list was enough to prompt you to keep your cell phone down for a bit, and maybe look to the person sitting next to you for some entertainment at least that won't cause you brain damage anytime soon!
Mobile or cell phones are now a days an integral part of modern telecommunications in every individual life. In many countries, over half of the population use mobile phones and the mobile phone market is growing rapidly. Saudi Arabia rank first among the countries of the gulf region with highest proportion of mobile users, a study conducted by United Nations Conference on Trade and Development (UNCTAD). In gulf countries, Oman ranked second, followed by Kuwait and the UAE. As billions of people use mobile phones globally, a small increase in the incidence of adverse effects on health could have major public health implications on long term basis. Besides the number of cell phone calls per day, the length of each call and the amount of time people use cell phones are important factors which enhance the health related risk. (1)
Mobile phones emit radiofrequency energy, a form of non-ionizing electromagnetic radiation, which can be absorbed by tissues close to the phone. The amount of radiofrequency energy a mobile phone user is exposed depend on many factors as the technology of the phone, the distance between the phone and the user, the extent and type of mobile phone use and the user’s distance from cell phone towers. (2)
In 2011, International Agency for Research on Cancer (IARC) classified mobile phone radiation possibly carcinogenic, means that there “could be some risk” of carcinogenicity, so additional research into the long-term, heavy use of mobile phones needs to be conducted. (3)
While an increased risk of brain tumours from the use of mobile phones 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, potentially longer lifetime of exposure, WHO has promoted further research on this group and is currently assessing the health impact of RF fields on all studied endpoints. A cohort study in Denmark linked billing information from more than 358,000 cell phone subscribers with brain tumour incidence data from the Danish Cancer Registry. The analyses found no association between cell phone use and the incidence of glioma, meningioma, or acoustic neuroma, even among people who had been cell phone subscribers for 13 or more years. (4)
The American Cancer Society (ACS) states that the IARC classification means that there could be some risk associated with cancer, but the evidence is not strong enough to be considered causal and needs to be investigated further. Individuals who are concerned about radiofrequency exposure can limit their exposure, including using an ear piece and limiting cell phone use, particularly among children. (5)
Scientists have reported adverse health effects of using mobile phones including changes in brain activity, reaction times, and sleep patterns. More studies are underway to try to confirm these findings. When mobile phones are used very close to some medical devices (including pacemakers, implantable defibrillators, and certain hearing aids) there is the possibility of causing interference with their operation. There is also the potential of interference between mobile phones signals and aircraft electronics. Some countries have licensed mobile phone use on aircraft during flight using systems that control the phone output power.
Research has shown an increased risk of traffic accidents, about 3–4 times greater chance of an accident, when mobile phones (either handheld or with a “hands-free” kit) are used while driving due to distraction. (6)
Children have the potential to be at greater risk than adults for developing brain cancer from cell phones. Their nervous systems are still developing and therefore more vulnerable to factors that may cause cancer.
The FDA (7) have suggested steps to reduce the exposure to radiofrequency energy:
Reserve the use of cell phones for shorter conversations or for times when a landline phone is not available.
Use a hands-free device, which places more distance between the phone and the head of the user.
