Is 5G Harmful to Humans? Here’s What Scientists Say...!

A major scientific study has addressed persistent public concerns over the potential health risks of 5G technology associated with smartphones. The research conclusively found that high-intensity 5G electromagnetic waves do not have any harmful biological effects on human cells. It dismissed claims that 5G radiation causes non-thermal biological damage.

This study was conducted by scientists from Constructor University in Germany and was published in the reputed scientific journal PNAS Nexus. As part of the research, scientists collected human skin cells—specifically fibroblasts and keratinocytes—and exposed them to high-intensity 5G electromagnetic waves. They used millimeter-wave bands between 27 gigahertz (GHz) and 40.5 GHz, which are expected to become widely adopted in future 5G applications.

The cells were subjected to these electromagnetic fields for durations ranging from two to 48 hours. The researchers intentionally used radiation levels far exceeding the limits recommended by international safety guidelines. "Our objective was to evaluate the impact of 5G under the most extreme conditions," the researchers reportedly stated.

Despite such intense exposure, the study found no significant changes in gene expression or DNA methylation patterns in the human cells. Both are critical indicators of cellular health and performance. Scientists explained that while frequencies up to 3 GHz can penetrate skin up to about 10 millimeters, frequencies of 10 GHz or higher can only reach about 1 millimeter deep, significantly reducing the likelihood of deep biological effects.

It is already known that high-intensity radio frequencies can cause heating in tissues. However, this study specifically excluded thermal effects and focused solely on non-thermal biological impacts. The core conclusion, the researchers stated, is: “No harm occurs as long as heating does not happen.” The study further remarked, “Our data raise fundamental doubts about claims suggesting non-thermal biological impacts of 5G radiation.”

The researchers expressed hope that this study would help dispel baseless speculation and provide evidence-based clarity on 5G health concerns. They emphasized the importance of educating the public about how electromagnetic radiation works within safe limits. However, experts also noted that concerns persist regarding the excessive use of screens and wireless devices, which may indirectly affect mental and physical health.
