Grade A · Meta-Analysis
Storms & Cardiovascular Risk (Population)
28 of 36 epidemiological studies report statistical links (RR 1.3–1.5) across millions — never individual causation.
Grade B · Cohort Studies
Blood Pressure & HRV Autonomic Adaptation
Cohort tracking links geomagnetic disturbance days with small BP shifts; higher resting HRV buffers storm stress.
Grade C · Mechanistic Hypothesis
Melatonin Rhythm & Individual Headache
Pineal melatonin modulation remains a hypothesis; zero peer-reviewed studies can blame one person's migraine on a flare.
