Should cell phones having warning labels on them, like cigarettes? People who used cell phones for 50 minutes had “increased brain glucose metabolism” in the region of their brain that was closest to the antenna. That’s according to a study on cell phone use and brain activity, published in the Journal of the American Medical Association.
What does that mean? I have no idea, and neither do the scientists.
When more glucose is being used up in the brain, it means that brain cells are being stimulated. That’s all researchers can conclude from the JAMA study.
The problem is that no one really knows the effects of long-term cell phone use. Scientists have been concerned about a potential link between cell phone radiation and brain cancer, but studies so far have been inconsistent.
Still, a recent study by the journal BioElectromagnetics found cell phones to be safe, since the U.S. and U.K. have not seen a surge in people diagnosed with brain tumors.
But other scientists have pointed out that a cancer generally takes 10 to 30 years to develop after an exposure.
What they do agree on is the need for more in-depth research in this area. In the meantime, advocacy group Environmental Health Trust advises consumers to follow safe cell phone practices, like reducing call times and using speakerphones and headsets. [HealthyState.org]
