Story summary

A Brazilian study links geomagnetic disturbances to higher heart-attack admissions over several years.
Researchers analyzed data by age and sex, finding women aged 31-60 had higher rates during disturbed geomagnetic conditions.
The study notes a significant association with solar activity but does not prove causation.
Men had nearly double overall rates, but the storm-related increase was smaller; study is needed.
