Dark Side of Mobile Phones 

     The usage of smart phones in the whole world  drastically increased by the last decade. Of course there are so many benefits of using smart technology however let's discuss  some disadvantages:

                                       -> Radiation 

       

                             

                             Korea's Thyroid-Cancer “Epidemic” — Screening and Overdiagnosis

  According to the New England Journal of Medicine, South Korea has experienced a thyroid cancer epidemic in recent years. The authors of this paper attribute the "epidemic" to a government-sponsored cancer screening program. As evidence, they report, 

"There was a strong correlation between the proportion of the population screened in a region in 2008 and 2009 and the regional incidence of thyroid cancer in 2009. Although the aggregate correlation could be vulnerable to the ecologic fallacy, the finding of significant positive correlations in each of eight age- and sex-based groups suggests that the finding is more robust." 

That widespread screening identifies more cancer is not surprising. This could at least partly explain the increasing incidence of thyroid cancer observed in South Korea, and nine other countries including the U.S. Could exposure to the electromagnetic radiation (RF and ELF) emitted by cell phones and cordless phones be contributing to this worldwide thyroid cancer epidemic? This question is still under research.

A headline in Haaretz a year ago March reads, "Israeli scientists find possible link between cellphone use, thyroid cancer."

 In the present study we investigated the possible histopathological effects of pulse modulated Radiofrequency (RF) fields on the thyroid gland using light microscopy, electron microscopy and immunohistochemical methods. The overall findings indicated that whole body exposure to pulse-modulated RF radiation that is similar to that emitted by global system for mobile communications (GSM) mobile phones can cause pathological changes in the thyroid gland by altering the gland structure and enhancing caspase-dependent pathways of apoptosis.

                                                  -> Eye Sight Problem      

  

"Among patients visiting our clinic, over 30 percent complain of eye diseases related to smartphones, such as dry eye syndrome, presbyopia, and pseudomyopia," said Dr. Jwah Woon-bong at Kangnam Eyence Eye Clinic in southern Seoul. The ratio of smartphone users is higher among young people. Among those in their 20s in the country, 94 percent use smartphones, and this ratio is 84 percent among those in their 30s. Three out of four teenagers also use the gadgets, which supports the idea that smartphone related problems are likely to increase in the future.  * http://www.koreatimes.co.kr/www/news/culture/2013/08/316_134244.html                                                                                    -> Other issues There is , actually, a big list of issues related to mobile phone usage and human health. In my blog I brought only two global issues as well as Korean issues. By the conclusion I want to ask one question. Have you ever hear this phrase:  “Mobile phones have 18 times more bacteria than toilet handles.”  Probably after reading this phase you might go and clean your phone, well, it is good idea! Believe me, I didn't want to scare anybody, just share some information about mobile phones hazards. Take care and use your cell phone in smart way~
