What is a long-term effect of talking on my cell phone a lot?

Dr. Mehmet Oz, MD
Cardiologist (Heart Specialist)

No one knows for sure what the long-term effects of cell phones on brain cells will be. But based on some data that shows that brain cells are affected by the cell phone—if you look at the brain cells on the right side of your brain versus the left side, when you're listening with the cell phone on the right side, they're a little different—there may be some problems down the road.

While cordless cell phone receivers do reduce the amount of energy from the cell phone that reaches your head, their effects are also unknown. They're probably beneficial, but they are receivers, so they might receive other energy from other places as well. Doctors are not quite sure about those yet. Don't throw away your cell phone away, but at least think about how much you're on the cell phone.

The safest solution is using the speaker phone option. The distance that you hold the phone away will cut the amount of energy reaching your brain by a quarter. So it's a lot if you can pull it farther from your head. Or, even better, stick to the land line if you can.
