According to a new study, funded by the American government, the radiation emitted from a cell phone after 50 minutes of use increases activity in brain cells. When compared to cell phones that were not in use (whatever that means-not next to ones skull?) the off phones did not show the same results.
The small study, published in the Journal of American Medical Association, is the first to look specifically at how electromagnetic radiation from cell phones affects glucose metabolism, a normal function, in the brain
"When glucose metabolism goes up, it activates cells. The findings are an indication that exposure to cell phones activate the brain much more easily than we previously thought," said Dr. Nora Volkow, National Institutes of Health neuroscientist and lead study author.
Brain activity means that the cells are using glucose to create energy. The brain normally produces the amount of glucose it needs to function properly. But these new findings don't tell us whether activating the cells artificially, in this case by cell phone radiation, will have a negative effect on health. Volkow says she simply doesn't know and calls for further investigation.
