Space weather hazards and their impact on human cardio-health state parameters on Earth
"The statistical significance of the influence of geomagnetic activity levels and cosmic ray intensity variations on heart rate and RR intervals was estimated. Results revealed that heart rate increase and RR intervals variations were more pronounced for high levels of geomagnetic activity and large cosmic ray intensity "
I suspect that during a period where we are not as protected by our magnetosphere, these events play a role in the more chaotic times in society.
