Status of the Neuroendocrine System in Animals Chronically Exposed to Electromagnetic Fields of 5G Mobile Network Base Stations
Abstract
Overview
We investigated the biological impacts of chronic exposure to multifrequency electromagnetic fields that simulate the effects of 5G NR/IMT-2020 mobile communication systems on male Wistar rats.
Methods
- Animals were exposed to 24-hour radiation at a power density of 250 μW/cm2 over 4 months.
- Both the exploratory activity and blood concentrations of ACTH and corticosterone of the animals were assessed monthly during exposure and one month post-exposure.
Findings
The chronic exposure notably affected the functional activity of the hypothalamus-pituitary-adrenal axis, indicating that the exposure was stressful for the animals.
- Notable waveform changes in serum levels of ACTH and corticosterone were observed.
- Enhanced serum corticosterone levels were more pronounced, with significant differences from the control groups noted after 1 and 2 months of exposure, peaking one month after exposure cessation.
- While changes in exploratory and emotional behavior were observed, they did not achieve statistical significance; normalcy returned a month post-exposure.
Conclusion
This study underscores the potentially stressful effects of 5G electromagnetic fields on the neuroendocrine system of exposed animals, highlighting the need for deeper investigations into the long-term health implications of chronic exposure to 5G EMFs.
