Abstract

Overview

The study focuses on the effects of Extremely Low Frequency Electromagnetic Fields (ELF-EMFs) on cortisol secretion among workers in high-voltage environments.

Findings

  • Examined the relationship between ELF-EMF exposure (50 Hz) and cortisol levels in 14 men working near high-voltage substations.
  • Magnetic field strength measured; exposure assessed over a week with dosimeters.
  • Comparative analysis indicated significant differences in cortisol levels between exposed workers and unexposed controls.
  • Long-term exposure linked to altered cortisol secretion patterns, raising concerns about broader health implications including cancer risks.
  • Highlighted the necessity for further research on vulnerable populations like children and the elderly.

Conclusion

The study provides evidence that chronic exposure to ELF-EMFs can disrupt normal cortisol production, indicating potential health risks including hormonal imbalances and associated diseases. Calls for ongoing monitoring and research into biological effects of long-term ELF-EMF exposure.
