How do 5G waves affect human skin?

(Dan Tri) - A recent study from scientists at Constructor University (Germany) has given an official answer to this question.

Research on 5G waves to clarify the impact on cells in the body (Illustration: Adobe).

Accordingly, the research team conducted an experiment by exposing two types of human skin cells directly to 5G electromagnetic waves under strictly controlled conditions.

The frequencies used in the experiment were up to 27GHz and 40.5GHz; much higher than the current commercial 5G wave frequencies.

Additionally, the intensity levels used in the study were deliberately pushed beyond normal safety levels to simulate worst-case scenarios. At the same time, the test lasted continuously for 48 hours, a period long enough to detect any abnormal biological reactions, if any.

The results showed absolutely no significant changes in the way the cells functioned after exposure.

Scientists focused on analyzing two key indicators: Gene expression and DNA methylation levels, fundamental factors that represent cell stability and potential for mutation.

Both of these metrics were reportedly unaffected, regardless of the frequency or intensity of the electromagnetic waves.

This is clear evidence that 5G waves, even at higher than normal levels, do not harm human skin cells.

Additionally, the study focuses on clarifying a major concern related to the heat factor caused by radio waves.

In theory, high frequency waves can increase the temperature of biological tissue, leading to thermal injury if it exceeds a safe threshold.

However, the authors took this factor seriously by strictly controlling the temperature throughout the entire experiment, ensuring that any potential effects from 5G were clearly separated from those caused by heat.

It was concluded that, except for a slight increase in temperature, there were no other negative effects on the cells under the experimental conditions.

Accordingly, it can be seen that 5G waves do not pose a biological threat and are completely safe to use, although the security of 5G is still in doubt.
