A device that connects the world could in fact be damaging to our health.
A recent study from the National Institutes of Health reported that low levels of radiation emitted from cellphones are shown to affect the brain.
The research, published in The Journal of American Medical Association, demonstrated that weak radio-frequency signals from cellphones can alter brain activity. It shows a 7 percent increase of brain activity, nearest to where the phone antenna is located.
However, researchers still are uncertain if the effects are harmful.
Professor Emeritus of neuroscience Christiana Leonard said it’s difficult to imagine what the short- and long-term effects are.
“The report is cause for concern, given the industry’s repeated assurances that there are no effects,” Leonard said.
She suggests animal studies should be used to investigate whether permanent tissue characteristics can be seen after long-term use and whether the two are proportional.
