View Original AbstractRats exposed to an extremely low frequency magnetic field for 4 h/day showed increased anxiety-like behaviors, while 1 h/day had no effect.
Plain English Summary
The study investigated whether anxiety levels could be affected by repeated extremely low frequency magnetic field (ELF MF) exposure of different daily durations. Rats exposed for 4 h/day showed increased anxiety-like behaviors in the open field test and the elevated plus maze test, without changes in locomotor activity, but showed no effect in the light/dark box test. Rats exposed for 1 h/day showed no effect in any of the tests.
Why This Matters
The researchers used multiple behavioral tests to assess anxiety, including an open field test, an elevated plus maze test, and a light/dark box test. The anxiogenic effect was found to be dependent on the daily exposure duration. The researchers noted the effect appeared more sensitive to void space than to strong light.
Exposure Details
- Magnetic Field
- 2 mT
- Source/Device
- 50 Hz
- Exposure Duration
- 1 h/day or 4 h/day for 25 days.
Exposure Context
This study used 2 mT for magnetic fields:
- 100Kx above the Building Biology guideline of 0.2 mG
- 20Kx above the BioInitiative Report recommendation of 1 mG
Building Biology guidelines are practitioner-based limits from real-world assessments. BioInitiative Report recommendations are based on peer-reviewed science. Check Your Exposure to compare your own measurements.
Where This Falls on the Concern Scale
Study Details
The aim of the present study was to investigate whether the anxiety level could be affected by repeated ELF MF exposure of different daily durations.
Results demonstrated that MF exposure 4 h/day increased the anxiety-like behaviors in rats in the op...
