Natural killer cell activity decreases in workers occupationally exposed to extremely low frequency magnetic fields exceeding 1 microT
Authors not listed · 2009
Workplace magnetic field exposure above 1 microTesla significantly weakens immune system defenses against cancer and infections.
Plain English Summary
Researchers measured magnetic field exposure in 121 workers and tested their immune system function. Workers exposed to magnetic fields above 1 microTesla showed significantly reduced natural killer cell activity, which are crucial immune cells that fight cancer and infections. This suggests workplace EMF exposure may weaken immune defenses.
Why This Matters
This study provides compelling evidence that occupational EMF exposure compromises immune function at levels many workers encounter daily. Natural killer cells are your immune system's first line of defense against both cancer cells and viral infections. When these cells don't function properly, your body becomes more vulnerable to disease. What makes this research particularly significant is the exposure threshold: 1 microTesla. That's a level you might encounter working near electrical equipment, in manufacturing facilities, or even in some office environments with heavy electrical infrastructure. The science demonstrates a clear dose-response relationship, with higher exposures showing greater immune suppression. This isn't just theoretical harm - it's measurable biological dysfunction that could translate into real health consequences over time.
