Unraveling the 5G Enigma: A Look at Brain Activity

As 5G technology continues to roll out, questions about its safety have been a hot topic. A recent study titled “Assessment of Electrical Brain Activity of Healthy Volunteers Exposed to 3.5 GHz of 5G Signals within Environmental Levels: A Controlled-Randomised Study” aims to shed light on this issue.

The Source Article Details

Assessment of Electrical Brain Activity of Healthy Volunteers Exposed to 3.5 GHz of 5G Signals within Environmental Levels: A Controlled-Randomised Study by Layla Jamal et al. in 2023.

The Source Article's Abstract

Background

Following the recent deployment of fifth-generation (5G) radio frequencies, several questions about their health impacts have been raised. The study aimed to investigate the bio-physiological effects of a generated 3.5 GHz frequency on the wake electroencephalograms (EEG) of 34 healthy volunteers.

Methods

The sessions were a maximum of one week apart, and both contained an exposure period of approximately 26 min and were followed by a post-exposure period of 17 min. The power spectral densities (PSDs) of the beta, alpha, theta, and delta bands were then computed and corrected based on an EEG baseline period.

Results

A statistical analysis showed an overall non-significant change in the studied brain waves, except for a few electrodes in the alpha, theta, and delta spectra.

Conclusion

This study showed that 3.5 GHz exposure, within the regulatory levels and exposure parameters used in this protocol, did not affect brain activity in healthy young adults.

International Journal of Environmental Research and Public Health, 20(18), 6793-6793. 10.3390/ijerph20186793

The Experiment: Setting the Stage

The study involved 34 healthy volunteers who were exposed to 3.5 GHz of 5G signals. The experiment was carefully designed to mimic real-world conditions, with the electromagnetic fields emitted in an electrically shielded room.

The sessions were spaced a week apart and included both “real” and “sham” exposure sessions, lasting approximately 26 minutes each. The study also included a post-exposure period of 17 minutes.

What the EEG Tells Us

Electroencephalograms (EEG) were used to measure the brain activity of the volunteers. The study focused on the power spectral densities (PSDs) of different brain wave bands: beta, alpha, theta, and delta.

Interestingly, the study found an overall non-significant change in brain activity, except for minor fluctuations in the alpha, theta, and delta spectra.

Implications for Public Health

The study is particularly important as it is one of the first to investigate the effects of 5G on human brain activity. The findings suggest that 5G exposure, at least under the conditions tested, does not have a significant impact on brain activity.

This could be a stepping stone for future research, especially as 5G technology continues to evolve and become more widespread.

FAQs

  • Does 5G affect brain activity? According to this study, no significant changes were observed.
  • How reliable are the results? The study was a randomized controlled trial, which is a high level of evidence in the EBM pyramid.
  • What’s next? More research is needed to confirm these findings and explore other potential health impacts of 5G.

So, what do you think about the impact of 5G on brain activity? Is it a cause for concern or a technological advancement we should embrace? Leave your thoughts below.
