Millimeter-wave high frequency 5G (26 GHz) electromagnetic fields do not modulate human brain electrical activity.

Area of Science:

• Neuroscience
• Electromagnetic Field (EMF) Research
• Telecommunications Engineering

Background:

• 5G networks use millimeter-wave (mmWave) frequencies like 26 GHz.
• Concerns exist regarding potential neurophysiological effects of mmWave exposure.
• Controlled studies on 26 GHz exposure and human brain activity are lacking.

Purpose of the Study:

• To investigate the effects of 26 GHz electromagnetic field (EMF) exposure on human electroencephalogram (EEG) activity.
• To assess potential neurophysiological changes in healthy adults exposed to 5G mmWave frequencies.
• To provide preliminary safety data for the deployment of 5G technology.

Main Methods:

• A randomized, triple-blind, crossover study involving 31 healthy adults.
• Participants underwent two sessions: real 26 GHz exposure (26.5 min at 2 V/m) and sham exposure.
• EEG was recorded before, during, and after exposure, with analysis of delta, theta, alpha, and beta frequency bands.

Main Results:

• No significant modulation of EEG power spectral density was observed in any frequency band.
• Statistical analysis showed no main effects or interactions for exposure conditions.
• This study is the first controlled investigation of 26 GHz 5G effects on human EEG.

Conclusions:

• Exposure to 26 GHz EMF under regulatory-compliant conditions did not alter human EEG activity.
• Findings suggest no detectable changes in brain electrical activity related to 26 GHz 5G exposure.
• Further research is warranted across diverse populations and exposure scenarios for comprehensive safety assessment.
