Conspiracy theories about cell towers and wireless communications have existed since the first days of these technologies. However, in an age where disinformation spreads rapidly, these theories have become more widespread and persistent than ever. 5G technology, in particular, has become the focus of these conspiracy theories, both because it was released at the same time as the COVID-19 pandemic and because it has become the subject of outrageous claims such as the “microchip vaccine.”

Although there is no scientific basis for these claims, researchers from Constructor University in Germany conducted a new study to clarify this issue. The study, published in the May issue of the journal PNAS Nexus, once again revealed that 5G's electromagnetic fields do not pose any harm to human health.

HUMAN CELLS EXPOSED TO 5G

5G networks operate within specific frequency ranges. While all 5G networks currently operate below 6 gigahertz (GHz), these frequencies are expected to expand to 24.3–27.5 GHz and 39.5–43.3 GHz in the coming years. However, these frequencies can only be absorbed by the body to a depth of a few millimeters. This means that these signals do not have any damaging effects on internal organs or DNA.

As part of the research , scientists exposed fibroblast and keratinocyte cells in human skin to electromagnetic waves of varying intensities at frequencies of 27 and 40.5 GHz for both short (2 hours) and long (48 hours) periods. Moreover, this exposure was 10 times more intense than the recommended limits.

The most striking aspect of this study is the methods used. The researchers examined possible changes in the genetic and epigenetic structures of the cells using advanced techniques such as whole-genome RNA sequencing and methylation sequencing. In other words, whether 5G signals affect the functioning or genetic structure of the cells was tested comprehensively.

RESULT: THERE IS NOT THE SLIGHTEST CHANGE IN THE GENETIC STRUCTURE

The results of the study were clear: 5G frequencies did not cause any changes in gene expression or DNA methylation in human cells beyond random levels.

The researchers summarized this result as follows:

"The quantum energies at the frequencies tested are too low to produce a photochemical or ionizing effect. Our findings are fully consistent with biophysical facts. But more importantly, they demonstrate that temperature effects must be carefully controlled and compensated for if necessary in such studies."

Because it is thought that some studies that previously reported negative results about 5G did not control for this temperature effect, that is, the changes in the cells were actually caused by heat.
