Abstract

Overview

The research explores how local extremely low-frequency magnetic fields (ELF-MFs) affect sleep induction and anxiety levels in male rats, stressing the public health implications due to its effects on sleep quality and potential anxiety modulation.

Methods

  • Forty male rats were divided into four groups (n=10 each).
  • Groups were exposed to ELF-MF at 0, 10, and 18 Hz at 200µT for 10 minutes per day over three days.
  • Control (sham-treated) group did not receive any ELF-MF exposure.
  • Assessments: Serum oxalic acid levels and behavioral changes measured using elevated plus maze and open-field test (OFT).

Findings

  • Significant reduction in serum oxalate levels in rats exposed to 10 Hz ELF-MF.
  • Behavioral assessments post-exposure indicated significant modulation in anxiety-like behavior and movement activities.

Conclusion

The study confirms that short-time exposure to ELF-MF can modulate metabolic and behavioral parameters in male rats, implicating potential risks to organisms exposed to such fields, reflecting the importance of regulating exposure durations and intensities.
