K, so, for whatever reason, this decade has been popular for articles from seemingly scientific sources saying that geomagnetic storms are causing negative health effects on the body, through magnetic field fluctuations. I looked it up…and during the most extreme geomagnetic storms, Earth’s magnetic field fluctuates at a rate of about 500 nanotesla per minute. Is that rate of change enough to induce enough of a current that it acts as a cellular stressor?
edit: I was reading through a Reddit thread earlier where ER staff mentioned how during geomagnetic storms the ER is unusually busy and how their hospital is considering installing magnetic field detecting devices so they can plan accordingly…?
This study accounted for weather, and found an increased rate of nearly 30 percent in heart attacks (MI) during geomagnetic storms. https://doi.org/10.1007/s00484-013-0660-0 That is massive, akin to the increase you’d expect during an environmental catastrophe, such as a severe heatwave or something.
Those methods are prone to false positives, a large US study found it more like 0.31% increase in MI deaths, which is more than 24 hour PM2.5 but less than the effect the cold season

Sample size and demographic makeup could skew things like that.
