Cell Phones May Alter Brain Activity

Yesterday while reading the Worcester Telegram and Gazette,I came across an article on radiation and cell phones.
Researches from the National Institutes of Health have found that less then one hour of cell phone use can speed up brain activity in the area closest to the phone antenna.Once again raising new questions about effects of low level radiation emitted from cell phones.
The researcher led by Dr.Volkow,director of the National Institute of Drug Abuse,
urged caution in interpreting these new finding because its not known if the changes seen in brain scans have any meaningful effect on a person overall heath.
According to a published study found Wednesday in the Journal of the American Medical Association,is among the the first and largest to document that the weak radio frequency signals from cell phone alter brains activity.
The study is important because it documents that the human brain is sensitive to the electromagnetic radiation that is emitted by cell phones.
It also high lights the importance of doing studies to address the question of whether,or not,long lasting consequences of repeated stimulation over a 5,10 or 15 year period is important.
A few observational studies have suggested a link between heavy cell phone use and rare brain tumors,but the bulk of the available scientific evidence shows no added risk.
This study does not enlighten us in terms of whether this is detrimental or could even be beneficial,Dr.Volkow says it just tells us that even though these are weak signals the human brain is activated by them.
The researchers used brain scans to directly measure how the electromagnetic radiation emitted from cell phones affected brain activity.
Although an increase in brain glucose metabolism happens during normal brain function,the question is whether repeated artificial stimulation as a result of exposer to electromagnetic radiation might have a detrimental effect.
So whats the answer? Seems the former director of the University of Pittsburgh Cancer Center and prominent neurosurgeons urge people to use headsets as a precaution.
You never can be to safe when it comes to your brain.
