Scientists confirm, 5G waves do not harm human health

There is no evidence that 5G technology is harmful to health, as confirmed by a new scientific study that analyzed in detail the impact of the electromagnetic waves used by the 5G network, with the aim of putting an end to this debate.

During the COVID-19 pandemic, 5G has been the subject of conspiracy theories linking it to the virus, without any evidence.

But researchers at Constructor University have now exposed two types of human skin cells – fibroblasts and keratinocytes – to electromagnetic waves above recommended safety limits, for two and 48 hours.

The results show that permitted levels of exposure to 5G waves do not damage human skin or cause changes at the gene level or epigenetic patterns.

It is reported that the study was published in the journal PNAS Nexus.

"These results contribute to clarifying uncertainties," the authors say.

What did they test and why?

Mobile phones and similar devices transmit data wirelessly, via electromagnetic waves in specific frequency bands.

Due to increased traffic, these bands are becoming congested, so 5G technology was introduced, which uses a wider spectrum, including frequencies between 24.3 and 43.3 GHz.

While waves up to 3 GHz penetrate the skin to a depth of 10 mm, those above 10 GHz, which includes 5G, penetrate only 1 mm into the skin's surface.

Despite this, many have been concerned about the potential "invisible consequences" of 5G technology, especially when the higher frequencies begin to be used.

The problem, the researchers say, is that previous studies that have raised concerns have had serious methodological flaws, such as a lack of temperature control and opaque statistics.

What did this study show?

It is reported that the new study used blind testing and temperature control, meaning that all potential sources of error were eliminated.

Skin cells are exposed to 5G frequencies of 27 and 40,5 GHz, at varying levels of intensity, including levels well above recommended limits.

The results are clear: there were no significant changes in gene expression or epigenetic patterns (DNA methylation).

In other words, even under the most adverse exposure conditions, skin cells show no signs of damage.

What about tissue heating?

The authors note that very strong radiofrequency waves, such as those used in wireless networks, can heat tissue.

But this effect only occurs when exposure levels are much higher than safety standards.

In this study, temperature control also removed this effect, further questioning the existence of any biological effect unrelated to heat.

This study joins a growing body of scientific evidence confirming that 5G technology poses no risk to human health. If there's one thing we should be concerned about, it's not the signal itself, but the increased time spent in front of screens. /Telegraph/
