Study Shows Cell Phones Mess With Your Brain
My eleven-year-old daughter has been begging me to buy her a cell phone.
I have solidly stood my ground – it seems wrong on so many levels, not least of which are the risk factors. I’ve put a lot of time and energy into her health and safety, it seems counterproductive to me to let her put an electromagnetic field next to her developing brain.
Finally, some backup for my mother’s instinct: a study published this week in the Journal of American Medical Association shows conversations of less than an hour produce an increase in brain activity. Guess what we will be discussing at dinner tonight?
The study is small, but its results prove that further testing is warranted on the long term effects of cell phone use. Most importantly, it adds fuel to my fire: cell phones can be a dangerous tool for developing organs.
47 participants were tested between January and December of 2009. Cell phones were placed on each ear; on one occasion the cell phones were off, on the other they were muted but would receive calls and texts. After the 50-minute exposure period, each person was given a PET scan to measure their brain activity.
The resulting scans showed that when the phones were turned on, there were significant increases in the brain glucose – the main fuel source for the brain – closest to the phone antenna.
The researchers were led by Dr. Dr. Nora D. Volkow, director of the National Institute on Drug Abuse. She noted that whether cell phone radiation actually causes brain tumors is unresolved. “Further studies are needed to assess if the effects we observed could have potential long-term consequences.”
It is early days on these studies, I’m sure we will be bombarded by many more in days to come. And from what I witness, most kids use their phones for texting more than speaking. Nevertheless, when it comes to my child’s brain, better safe than sorry seems to be a fitting motto.
The other potentially bad news that could result from this study is an increase in the army of people who walk around talking to themselves. It always takes me a minute to determine they are actually using minute headsets…I’ll admit, it looks weird, but I’m buying one anyway.
