Abstract

Overview

Mobile phones are essential in modern daily life, yet there are widespread concerns about the adverse effects from the electromagnetic fields (EMF) they emit. This study investigates the impacts of long-term evolution (LTE) EMF on brain activity as recorded by awake electroencephalograms (EEG).

Participants and Method

Thirty-eight healthy volunteers, aged between 20 to 36 years, were exposed to LTE-like EMF for 30 minutes. The specific absorption rate (SAR) was measured at a maximum of 2.0 W/kg over a 10-g mass. EEGs were taken before and after both real and sham exposures.

Findings

• The analysis focused on EEG power spectrums in θ, α, and β frequency ranges.
• Enhancements in the θ and α band waves were observed following both types of exposure.
• The observed changes might be attributed to participants' drowsiness during EEG recording in both real and sham exposure scenarios.

Conclusion

Despite the modifications in EEG post-exposure, this study found no detectable harmful effects on the awake EEGs of healthy humans after a 30-minute LTE-like EMF exposure. However, ongoing research is needed to continually assess potential impacts and uphold EMF safety.
