Mobile phone use alters brain activity

Mobile phone use alters brain activityIt’s official: using a mobile phone melts your brain. Ok, not really. But, as reported by Reuters, a recent study has shown that spending 50 minutes on a call is enough to alter brain activity near the antenna.

What’s not clear yet is whether or not that activity causes any harm. And let’s not beat around the proverbial bush; when we say “harm” we mean “brain tumours”.

The study was conducted by the National Institute of Health, with the results published in the Journal of the American Medical Association.

Dr. Nora Volkow of the NIH explains: "What we showed is glucose metabolism (a sign of brain activity) increases in the brain in people who were exposed to a cell phone in the area closet to the antenna."

Volkow was reportedly surprised that the relatively weak radiation from mobile phones could alter brain activity, but reiterated that there’s still no conclusive link with cancer.

"This study does not in any way indicate that. What the study does is to show the human brain is sensitive to electromagnetic radiation from cell phone exposures."

The University of Washington’s Henry Lai, and Dr. Lennart Hardell of University Hospital in Orebro, Sweden, wrote: “Although the biological significance, if any, of increased glucose metabolism from acute cell phone exposure is unknown, the results warrant further investigation."

Professor Patrick Haggard from University College London pointed out that much larger fluctuations in brain actiivty can occur naturally, such as when a person is thinking.

However, Dr. Volkow now uses an ear phone, just to be on the safe side.

"I don't say there is any risk, but in case there is, why not?"

I suppose his earphones do NOT emit EMR? If cell phone doses, why not minute doses from earphones? It is curious how every single study related to the effects seems dodgy...wether pro or contra...
