Abstract

Overview

The study examines the influence of natural geomagnetic fields and geomagnetic storms on zebrafish's biological circadian rhythms.

Findings

• An observed decrease in swimming speed of zebrafish occurred due to geomagnetic disturbances occurring before or after diurnal geomagnetic variations.
• When geomagnetic perturbations coincided with diurnal geomagnetic fluctuations, the impact on zebrafish's swimming speed was minimal, indicating a potential synchronization with the circadian geomagnetic variations.

Conclusion

This research underlines the significant connection between geomagnetic disruptions and biological circadian rhythms, suggesting that disturbances in these rhythms could relate to broader medical or biological implications, including risks on health due to EMF exposure.
