New research has discovered that frequent cell phone use may increase activity in regions of the brain, causing some to question whether mobile devices may be harmful to human health.
To measure how cell phones may affect the brain, researchers from the National Institutes of Health analyzed 47 test subjects using the devices for various periods of time and while on, off, muted and held directly to the ear. Using PET scans to analyze brain activity, scientists discovered that after 50 minutes, the electromagnetic radiation emitted from the devices increased brain activity by 7 percent in areas near the phones antenna.
Nora Volkow, the leader of the study, told USA Today that while scientists still don't know how dangerous that radiation is, it may have negative effects for children and teens whose brains are still developing.
"In my case, I don't like my brain to be stimulated by anything that is not physiological," Volkow said.
For years, various studies have investigated the potentially dangerous effects of cell phone radiation on heavy users. While the National Cancer Institute reports there is currently no solid evidence to suggest that mobile phone radiation could be a risk factor for cancer, frequent cell phone users may want to purchase a life insurance policy as a precaution.
