Microwave radiation at cell phone frequencies caused measurable liver damage in rats, with antioxidants providing only partial protection.

Plain English Summary

Summary written for general audiences

Researchers exposed rats to cell phone-frequency radiation (900 MHz) for 4 hours daily and found significant liver damage after 20-60 days, including increased oxidative stress and cellular damage. Melatonin supplements provided only partial protection, suggesting microwave radiation harms liver tissue through multiple pathways.

Why This Matters

This study adds to growing evidence that radiofrequency radiation affects organs beyond the brain, demonstrating measurable liver damage at exposure levels comparable to prolonged cell phone use. The 900 MHz frequency and power levels used mirror real-world wireless exposures, making these findings particularly relevant for understanding cumulative health effects from our wireless devices. What's especially noteworthy is that even melatonin, a powerful antioxidant, could only partially protect against the oxidative damage. The science demonstrates that EMF exposure triggers multiple pathways of cellular harm simultaneously, which explains why simple antioxidant approaches may not provide complete protection. You don't have to eliminate all wireless technology, but this research reinforces why reducing unnecessary exposures and taking breaks from devices makes biological sense.
