how come your cellphone harms you

Cell phone use could increase the risk of brain tumor,
several western studies have warned. Now a new research claims that radiation from mobiles also affects human skin.
A team of scientists in Finland had carried out the research and found that living tissue responds to mobile phone radiation which alters protein expression in people, the ' BMC Genomics' journal reported.
According to lead researcher Dariusz Leszezynski of Finnish Radiation And Nuclear Safety Authority," Mobile phone radiation has some biological effect. Even if the changes are small, they still exist."
After the analysis of nearly 580 proteins, the researchers identified eight proteins which were statistically significantly affected.
According to Leszezynski, it is much too early to say will these changes induced by the mobile phone radiation have any effect on health.
A more extensive study with 50-100 volunteers was planned at STUK. The research was expected to begin in 2009.
Earlier studies had shown that mobile phone radiation changes protein expression and activity in human endothelial cell line.
The age of mobile devices reached a milestone last month. According to the latest research from the Pew Internet and American Life project, as of February, just over half of all U.S. adults own a smartphone . In fact, some readers are viewing this on a mobile device right now. If you’re reading this on your iPad or smartphone: how is your neck positioned? How close are you holding your device to your face? Staring down and squinting at a small, bright screen for several hours a day clearly isn’t healthy, and as a reminder the infographic below “Are Mobile Devices Destroying Your Body?” illustrates some of the health risks of mobile devices and provides some prevention tips.
Some of the statistics present may seem alarming, especially the one citing that “a recent WHO study showed a correlation between radiation from mobile devices and a brain cancer called glioma.” While it’s true that there was a recent World Health Organization (WHO) study [2], to date, no adverse health effects have been established as being caused by mobile phone use. Based largely on several large multinational epidemiological studies, the International Agency for Research on Cancer (IARC) has classified radiofrequency electromagnetic fields as possibly carcinogenic to humans, which is the category used when a causal association is considered credible, but when chance, bias or confounding cannot be ruled out with reasonable confidence.
Nevertheless, this infographic highlights some important issues (e.g. texting while driving) and offer some good tips for both mobile device and general computer use. In particular, computer vision syndrome (CVS) has been called a widely spreading but largely unknown epidemic among computer users. CVS affects just about everyone, including kids. To help prevent CVS, blink more often, use saline drops and find protective eye wear.
