Harmful effects of mobile phones on human health
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.
Mobile phones emit radiofrequency energy, a form of non-ionizing electromagnetic radiation, which can be absorbed by tissues close to the phone.
5 Reasons Why Cellphones Are Bad For Your Health
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 , 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. 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. 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. 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:. National Center for Biotechnology Information , U. Int J Health Sci Qassim. Zahid Naeem. In May , the World Health Organization 's International Agency for Research on Cancer announced it was classifying electromagnetic fields from mobile phones and other sources as "possibly carcinogenic to humans" and advised the public to adopt safety measures to reduce exposure, like use of hands-free devices or texting.
5 Harmful Effects Of Mobile Phones On Your Brain
Some national radiation advisory authorities, including those of Austria,  France,  Germany ,  and Sweden,  have recommended measures to minimize exposure to their citizens. Examples of the recommendations are:. The use of "hands-free" was not recommended by the British Consumers' Association in a statement in November , as they believed that exposure was increased. In , Professor Lawrie Challis and others said clipping a ferrite bead onto hands-free kits stops the radio waves travelling up the wire and into the head.
Several nations have advised moderate use of mobile phones for children. Also, with the permittivity of the brain decreasing as one gets older and the higher relative volume of the exposed growing brain in children, radiation penetrates far beyond the mid-brain. According to the FTC, "there is no scientific proof that so-called shields significantly reduce exposure from electromagnetic emissions.
