They tested two types of skin cells: fibroblasts and keratinocytes. Scientists exposed human skin cells to 5G frequencies for 48 hours.
5G and Human Skin Cells: No Harmful Effects Found
A new study has brought good news about 5G technology. Researchers found that 5G signals do not harm human skin cells. This study was published in the PNAS Nexus Journal by Oxford Academic.
What Did the Study Test?
The researchers wanted to see if 5G electromagnetic fields (EMF) could change the genes or DNA methylation in skin cells. DNA methylation is a process that can affect how genes work.
They tested two types of skin cells: fibroblasts and keratinocytes. Scientists exposed human skin cells to 5G frequencies for 48 hours. They used exposure levels 10 times higher than public safety limits.
What Did They Find?
The results were clear. 5G exposure did not cause any significant changes in the cells. The gene expression and DNA methylation stayed the same.The researchers also compared the results to cells exposed to UV radiation. Unlike 5G, UV radiation caused clear changes in the cells.
Why Is This Important?
Many people worry about the health effects of 5G. Indeed, some believe it could cause cancer or other problems. Actually, this study shows that 5G signals are safe for human skin cells, even at high levels.
How Was the Study Done?
The study used advanced methods like RNA sequencing and methylation analysis. Scientists exposed human skin cells to 5G frequencies for 48 hours. They increased exposure levels to 10 times higher than public safety limits. Additionally, the researchers ensured careful control of the experiments. They also used a blinded design. This means scientists didn’t know which cells were exposed to 5G until after the tests. This helps ensure the results are unbiased.
What Does This Mean for You?
This study shows that 5G technology is unlikely to harm your skin. Therefore, the researchers hope their findings will reduce public fears about 5G.
Final Thoughts
The study provides strong evidence that 5G signals are safe for human skin cells. As 5G continues to expand, this research helps ensure that the technology is both useful and safe.
