Abstract

Overview

This study investigates the effects of extremely-low frequency electromagnetic fields (ELF-EMFs) on cortisol secretion in workers frequently exposed to these fields due to their proximity to high voltage substations and transmission lines.

Findings

  • The study involved 14 men with a long history (1-20 years) of exposure to ELF-EMFs, analysing their cortisol levels compared to age-matched unexposed controls.
  • Magnetic field strength ranged from 0.1 to 2.6 μT, measured over a week using Emdex dosimeters.
  • Significant differences in cortisol patterns were observed between exposed groups and controls, indicating an impact of EMF exposure on cortisol levels.

Conclusion

The chronic exposure to ELF-EMFs is suggested to alter peak-time serum cortisol levels, warranting further research on its broader impacts, especially in vulnerable groups such as children and the elderly.
