Plain English Summary
Researchers exposed human immune cells to cell phone radiation at typical frequencies for 30 minutes to 1 hour. The extremely weak signals - 200 times below safety limits - triggered DNA packaging changes resembling heat stress in most subjects, suggesting cellular effects from everyday phone use.
Why This Matters
This study delivers a crucial insight into how cell phone radiation affects our cells at the most fundamental level. The researchers found that GSM frequencies - the same ones your phone uses to make calls - caused changes in how DNA is packaged inside immune cells, creating a stress response similar to heating cells to 104-111°F. What makes this particularly significant is the extraordinarily low exposure level: just 5.4 milliwatts per kilogram, roughly 200 times below current FCC safety limits. The fact that most donors showed cellular responses at such minimal exposures challenges the industry narrative that only thermal effects matter. The research also revealed important individual variations in sensitivity, with some people's cells responding more strongly than others - a finding that aligns with growing evidence of electromagnetic hypersensitivity in the population.

Where This Falls on the Concern Scale
Study Details
Here we investigated whether microwaves (MWs) of Global System for Mobile Communication (GSM) induce changes in chromatin conformation in human lymphocytes.
Effects of MWs were studied at different frequencies in the range of 895-915 MHz in experiments with...
30-min exposure to MWs at 900 and 905 MHz resulted in statistically significant condensation of chro...
The conclusion-GSM microwaves under specific conditions of exposure affected human lymphocytes similar to stress response. The data suggested that the MW effects differ at various GSM frequencies and vary between donors.
