Geomagnetic Storms Linked to Stroke Risk
the MPR take:
While there are numerous risk factors for stroke, geomagnetic storms could be added to that list. A review in the journal Stroke analyzed data from 6 population-based stroke incident studies of 11,453 patients from 1981–2004 in New Zealand, Australia, United Kingdom, France, and Sweden and found that geomagnetic storms were associated with a 19% increase in stroke risk occurrence. The effect was most evident in individuals <65 years of age and during severe/extreme geomagnetic storms. It is hypothesized that geomagnetic storms increase blood pressure and impact heart rhythms and blood clotting abilities, which are known risk factors for stroke.
Geomagnetic storms happen when the Earth's magnetic field is disturbed by solar winds or coronal mass ejections, which throw out powerful magnetic fields from the sun. Among more than 11,000 people who had a stroke, the event was almost 20 percent more likely to happen on days with geomagnetic ...
