Radiofrequency Electromagnetic Field Exposure and the Resting EEG: Exploring the Thermal Mechanism Hypothesis
Abstract
Overview
There is extensive evidence pointing towards the impact of radiofrequency electromagnetic field (RF-EMF) exposure on human electroencephalogram (EEG) recordings, specifically affecting the alpha band during rest.
Findings
- A controlled study involving thirty-six healthy adults was conducted in a randomized, double-blind, counterbalanced setup to determine the potential thermal mediation of RF-EMF effects on EEG.
- Participants wore a water-perfusion suit at 34°C to stabilize skin temperature and negate environmental variation.
- The study included one calibration session followed by three exposure sessions, where EEG and skin temperatures were recorded. Exposures included Sham, Low RF-EMF (1 W/kg), and High RF-EMF (2 W/kg) conditions over 30 minutes each.
- Results corroborate previous findings where higher alpha EEG activity was observed during the high exposure condition compared to Sham. Additionally, finger temperature, indicating thermoregulatory responses, was elevated in both exposed conditions relative to Sham.
Conclusion
The link between EEG alterations and RF-EMF exposure may be explained via thermoregulatory mechanisms. These findings affirm the potential health risks associated with RF-EMF exposure, underscoring the need for ongoing research and precautionary measures in the use and exposure of EMF technologies.
