Abstract

Overview

The rapid development of technologies that use weak static magnetic fields (SMF) poses potential concerns regarding their effects on biological systems. This systematic review focuses on evaluating such effects, particularly in the context of weak SMF exposures (≤ 1 mT).

Methods

• Followed PRISMA guidelines for systematic reviews.
• Assessed methodological limitations via the OHAT Risk-of-Bias Rating Tool.

Findings

Analysis included eleven experimental animal studies. Notable responses observed were in rats, rabbits, and quails which showed alterations in melatonin biosynthesis, locomotor activity, vasomotion, blood pressure, and other biochemical indicators related to health.

The significance of these findings for health is unclear due to the initial studies' limitations in determining whether these effects were beneficial or detrimental.

Conclusion

Current evidence is insufficient to conclusively determine the health-related effects of weak SMF. The presence of experimental inconsistencies and methodological weaknesses calls for more rigorous and targeted research in this area, especially concerning human health.

Further Recommendations

Future research should aim to clarify the ambiguous results and focus more on human biological responses to SMF exposure, exploring potential risks to human health more thoroughly.
