Researchers Exposure of Human Cells to 5G Radiation: Exploring Potential Results
A recent study conducted by researchers from Constructor University has found that exposure to electromagnetic waves from 5G networks does not pose a health risk to human skin.
The study, published in PNAS Nexus on a Tuesday, was conducted at frequencies above 6 GHz, which are the frequencies that 5G networks will operate on in the near future. The researchers exposed two types of human skin cells, fibroblasts and keratinocytes, to 5G electromagnetic waves at 27 and 40.5 GHz frequencies with varying levels of intensity.
Under worst-case conditions, no significant changes in gene expression or methylation patterns were observed in human skin cells after exposure. This finding adds to a growing body of evidence showing that 5G cell phone signals do not pose a health risk to humans.
The study found that electromagnetic waves up to 3 GHz penetrate the skin at a depth of about 0.39 inches (10 millimeters), while waves at or higher than 10 GHz remain superficial, reaching at most 0.039 in (1 mm) deep. This means that the skin primarily absorbs 5G frequencies, which may induce biological effects such as possible oxidative stress and DNA damage. However, the evidence is mixed and complex.
Some recent research presented in 2025 examined how 27.5 GHz 5G frequencies impact neonatal skin, highlighting ongoing investigation into developmental sensitivity. However, the overall scientific consensus still calls for additional focused research to clarify potential risks, especially at exposure levels complying with international safety guidelines.
The researchers point out that frequencies above 6 GHz, when applied at intensities far exceeding safety reference levels, can cause heat-related damage. However, this study kept the intensities within safe levels and conducted temperature-controlled experiments to rule out possible nonthermal biological effects of exposure.
It is important to note that this study does not cast fundamental doubt on the existence of possible nonthermal biological effects of 5G exposure. However, the greater concern should be the impact of ever-increasing screen time on our well-being.
In the next couple of years, 5G will also operate on frequencies from 24.3 to 27.5 GHz and 39.5 to 43.3 GHz. Devices such as cell phones transmit data via electromagnetic waves within specific frequency ranges.
In summary, current evidence indicates potential biological effects of 5G electromagnetic waves on human skin cells, including DNA damage and oxidative stress, but these findings are not conclusively linked to adverse health outcomes and are influenced by exposure parameters. Precautionary measures alongside existing safety standards are recommended until more definitive data is available.
A recent study analyzed electromagnetic waves used by 5G networks, which were at the center of conspiracies linking the technology to COVID-19 infections. However, no evidence exists that cell phones compromise human health due to electromagnetic waves used by 5G networks.
- The study, published in PNAS Nexus, was conducted on two types of human skin cells, fibroblasts and keratinocytes, to investigate the potential health effects of 5G electromagnetic waves.
- The findings of the study suggest that under worst-case conditions, human skin cells do not show significant changes in gene expression or methylation patterns when exposed to 5G electromagnetic waves.
- In the near future, 5G networks will operate on frequencies above 6 GHz, a fact highlighted in the study that focused on the impact of 5G technology on health-and-wellness.
- Despite the potential biological effects of 5G electromagnetic waves on human skin cells, such as possible oxidative stress and DNA damage, the overall scientific consensus calls for more focused research to clarify potential risks, especially at exposure levels complying with international safety guidelines.
