New research has shown that when you put a cell phone next to your ear for 50 minutes while sitting in a positron emission tomography — or PET — scan machine, even though the phone is on mute, there is a 7 percent increase in activity (as measured by blood glucose levels) in the area closest to the cell phone’s antenna.
What does this mean? Since brain research is the “new frontier” no one knows for sure, but experts are recommending caution. They are saying you might consider switching ears while on the phone, don’t use them when your signal is weak and DO NOT sleep close to your phone. Allow at least 5 feet between you and your phone while sleeping!
