BETHESDA, M.D.— Most people can't seem to live without their cell phones, and new research shows using a cell phone can affect brain activity.
Cell phone usage— even minimal usage— can alter activity in our brain cells. The study finds that radio frequency signals from a mobile phone speed up the way brain cells metabolize glucose, which is the cell's energy source.
Neurologists said brain cells closest to the phone's antenna are put under stress. It is still unknown just how much stress affects brain cells, or how whether it is safe to put them under long periods of stress. Studies on whether cell phone usage causes brain tumors have been inconclusive.
It will take more years of additional study to determine what long-term effects cell phone usage can cause, if at all.
Regardless, more than 90 percent of the population uses a wireless device, and many of them are children and teenagers whom are still developing. About a quarter of U.S. households are wireless only.
Until these children and teens are adults, and scientists piece together all the facts, all conclusions are now on hold.
