Static magnetic fields alter blood cell counts and immune markers in direction-dependent ways, even without causing visible organ damage.
Plain English Summary
Summary written for general audiences
Researchers exposed spontaneously hypertensive rats to static magnetic fields (SMF) pointing upward or downward for an extended period. They found that magnetic field exposure altered blood cell counts and immune system markers, with different effects depending on field direction. Heart and kidney tissue showed no structural damage.

}Quick Questions About This Study
Yes, this study found that upward-oriented static magnetic fields decreased blood lymphocytes and bone marrow red blood cells, while downward-oriented fields increased bone marrow lymphocytes. Both orientations reduced platelet counts, showing direction matters for biological effects.
Rats exposed to downward-oriented static magnetic fields showed reduced anxiety-like behavior compared to controls. This suggests static magnetic field exposure can alter behavioral responses, though the mechanism and human relevance remain unclear from this single study.
Static magnetic field exposure decreased granulocytes (infection-fighting white blood cells) in both spleen and bone marrow regardless of field direction. This reduction in key immune cells could potentially affect the body's ability to fight infections.
No structural damage was observed in heart or kidney tissue after chronic static magnetic field exposure in this study. However, the lack of visible tissue damage doesn't rule out functional changes or molecular-level effects that weren't measured.
Yes, static magnetic fields don't oscillate like radiofrequency radiation from phones or WiFi. This study shows even non-oscillating magnetic fields can affect blood chemistry and behavior, demonstrating that EMF biological effects extend beyond just RF radiation.
