Plain English Summary
Researchers exposed wounded rats to different types of radiofrequency radiation for 30 minutes daily during the first 5 days of healing. They found that unmodulated RF radiation reduced inflammation and slowed healing, while modulated RF radiation (the type used in wireless communications) significantly increased inflammation and accelerated tissue formation. This demonstrates that RF radiation can directly alter the body's wound healing processes, with different effects depending on the signal characteristics.
Why This Matters
This study reveals something crucial that the wireless industry rarely discusses: the biological effects of RF radiation depend heavily on signal characteristics, not just power levels. The researchers found that modulated RF signals - the type used in all modern wireless devices - produced dramatically different healing responses than unmodulated signals. The modulated radiation significantly increased inflammatory markers and altered collagen production, showing that our bodies respond differently to the complex, pulsed signals from cell phones and WiFi compared to simple continuous waves. What makes this particularly relevant is that the frequencies tested (42-53 GHz) are now being deployed in 5G networks. The science demonstrates that RF radiation isn't just about heating tissue - it's about how these signals interact with fundamental biological processes like wound healing and inflammation.
Exposure Information
Specific exposure levels were not quantified in this study. The study examined exposure from: (1) 53.53 GHz without modulation; (2) frequency 42.19 GHz without modulation; (3) frequency 42.19 GHz, but with a frequency modulation band 200-MHz wide. Duration: 30 min daily during the first 5 day
Study Details
The effect of radio frequency electromagnetic fields (RF EMF) was studied on Wistar rats with excised full-thickness dermal wounds in the interscapular region.

Thus, our experiments confirm the effects of non-thermal EMF on the reparative-proliferative processes of animals with soft tissue wounds.
