The introduction of the advanced 5G cellular network has sparked a myriad of conspiracy theories and myths regarding potential health risks.

However, scientists have repeatedly debunked these claims and are now prepared to provide further evidence that smartphones do not pose a danger to people.

Research has revealed that 5G frequencies do not cause any alterations in human skin cells.

This information was published in the journal PNAS Nexus, according to Popular Science.

Cellular networks operate within designated frequency ranges, with 5G functioning at 6 gigahertz. It is expected that this range will soon be expanded from 24.3 to 27.5 and from 39.5 to 43.3 gigahertz.

While extremely strong electromagnetic fields can potentially cause physiological harm, 5G frequencies are unable to penetrate the body beyond a few millimeters of skin.

Researchers from the Constructor University (Germany) conducted an experiment to assess whether such cellular communication could harm humans.

They exposed skin cells to 5G frequencies and much stronger electromagnetic fields.

The team focused on testing two types of cells – fibroblasts and keratinocytes, which form connective tissue and most of the epidermis.

During a series of tests, the researchers subjected the cells to various frequencies for periods of two and 48 hours.

Subsequently, scientists analyzed how the action of electromagnetic fields affected human cells genetically and epigenetically (changes in gene characteristics and how they utilize hereditary information).

The results indicated that even at ten times the recommended exposure limits, the frequencies did not induce any changes. The authors of the study noted that these findings somewhat contradict previous work, as earlier researchers did not control for temperature during the experiment, which may have influenced the results.

"Our results align well with biophysical facts: at such frequencies, quantum energy is too low to induce photochemical or ionizing effects", the researchers wrote.

The authors hope their findings will finally "close the debate" on the "harmfulness of 5G".
