The effect of geomagnetic storms on suicide
AbstractObjectives: To correlate geomagnetic storm activity with suicide rates.
Design: A retrospective analysis over a 13 year period, Janaury 1980 to December 1992.
Setting: Hermanus Magnetic Observatory (data on geomagnetic storm activity), South African Central Statistical Services (data on suicide rates).
Outcome measures: Geomagnetic storm activity and suicide rates.
Results: A significant correlation (r= 0,6964 ; p< 0,01) was found between the mean total of suicides and the mean average of storm activity during the same period. This correlation was true of both male (r= 0,6301 ; p< 0,025) and female (r= 0,7544 ; p< 0,005) suicides.
Conclusions: Geomagnetic storm activity is correlated with suicide, and confirms previous research suggesting an impact of ambient magnetic field activity on behaviour.
