The narrative isn’t so much the static magnetic field but fluctuating/time varying magnetic fields induced on Earth during magnetic storms. When a magnetic field changes it can induce currents in tissues. It’s proportional to both the strength of the field and the rate of change. During an extreme geomagnetic storm, the rate of change can be up to 500 nanoteslas per minute.

Still insignificant. Solar storms and fluctuating magnetic fields have been happening for longer than humans have been here and have been happening while humans were here. Theres tons of pseudo-science gaining popularity online, can’t believe astrology is still so popular with people, and this sounds like one of them to be honest.

That means humans developed in an environment where these changes wee happening - so if it could affect us, natural selection would’ve compensated.
Just like how our lungs and cardio system is adapted to our nitrogen/oxygen atmosphere.

This study accounted for weather, and found an increased rate of over 20 percent in heart attacks (MI). 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.
