View Original AbstractMicrowave radiation damaged rats' heart pacemaker cells at power levels comparable to some wireless devices, with effects lasting up to 12 months.
Plain English Summary
Researchers exposed rats to pulsed microwave radiation and found significant damage to the sinoatrial node, the heart's natural pacemaker. At moderate to high power levels, the radiation caused cell swelling, structural damage, and permanent scarring that lasted up to 12 months, potentially affecting heart rhythm control.
Why This Matters
This study provides compelling evidence that microwave radiation can directly damage the heart's pacemaker system, the sinoatrial node that controls your heartbeat. What makes this research particularly concerning is that the damage wasn't temporary - structural changes and scarring persisted for the entire 12-month observation period. The exposure levels that caused damage (10-50 mW/cm²) are within ranges that can occur near high-powered wireless devices and cell towers, though typically much higher than what you'd experience from a cell phone held at arm's length. The science demonstrates that EMF exposure doesn't just affect brain tissue or reproductive organs, as often discussed, but can also impact the cardiovascular system in ways that could potentially affect heart rhythm regulation. This adds to the growing body of evidence showing that EMF bioeffects extend beyond heating, contradicting the wireless industry's position that non-thermal effects don't occur.
