Plain English Summary
Researchers exposed human white blood cells (lymphocytes) to cell phone radiation at levels similar to what phones emit during calls. They found that 30-60 minutes of exposure caused changes in the DNA packaging inside cells that were similar to heat stress damage. These cellular changes occurred in most test subjects and suggest that phone radiation may trigger stress responses in our immune cells even at low power levels.
Why This Matters
This study reveals something concerning about how cell phone radiation interacts with our immune cells at the molecular level. The researchers found that GSM phone signals at a SAR of 5.4 mW/kg triggered chromatin condensation - essentially causing the DNA packaging in lymphocytes to compress in ways typically seen during cellular stress or damage. What makes this particularly significant is that this SAR level is well within the range of everyday phone use. The fact that these effects resembled heat shock responses suggests our cells may be interpreting RF radiation as a stressor, potentially triggering protective mechanisms that weren't designed for chronic activation. The individual variation in response that the researchers documented also aligns with what we see clinically - some people appear more sensitive to EMF exposure than others. This adds to the growing body of evidence that our current safety standards, which only consider heating effects, may be missing important biological responses happening at the cellular level.
