How much more proof do we need that being online isn't healthy for us? The latest terrible tech research is from Kaiser Permanente. In a study of hundreds of pregnant women in the Bay Area, the authors found that those who were more exposed to the kind of radiation produced by cell phones, wireless networks and power lines were nearly three times as likely to suffer miscarriages. These electromagnetic fields, or EMFs, are around every single one of us. There will be tremendous pushback against any research showing how dangerous this stuff may be. An example: San Francisco's radiation-warning law, championed by then-Mayor Gavin Newsom, passed in 2010. But after a lawsuit from the cell phone industry, the city backed off on implementing it. Around the same time, the California Department of Public Health drew up its set of guidelines to inform the public about the risks associated with cell phone use. The health department then sat on these guidelines for seven years. The health department's lawyers ... argued that releasing the guidelines might cause the public to panic. Well, it might be time to start panicking. More and more, it sounds like the long-term effects of our Internet habits could be dangerous, not just for our relationships and our ability to focus, but our brains and bodies as well. The small-but-growing body of EMF research looks like anti-tobacco research must have looked in the 1950s - necessary and important work that will surely gain researchers an ugly, uphill battle against better-funded opponents.
