Peer-Reviewed Clinical Evidence Library (DOI-Verified)

Every study below is programmatically verified against Crossref and graded into Tier A/B/C so you can separate population statistics from mechanistic hypotheses.

Scoring Formula & Governance →
Grade A · Systematic Review https://doi.org/10.4103/jmp.jmp_122_24
Journal of Medical Physics (2025)

Geomagnetic storms and acute myocardial infarction / ACS risk (RR 1.3–1.5)

Synthesizes epidemiological cohorts confirming elevated acute coronary admissions during severe storms in clinically vulnerable groups.

Boundary: Population-level statistic only; never predicts individual cardiac events.
Grade A · Comprehensive Review https://doi.org/10.7759/cureus.99851
Cureus / Springer Nature (2025)

28 of 36 epidemiological studies report significant cardiovascular links; stroke risk up to +52% in severe storms

Reviews 36 human studies showing consistent population links for stroke and cardiovascular load while noting index heterogeneity.

Boundary: Observational latitude variance exists; individual causation remains unproven.
Grade B · Nationwide Cohort https://doi.org/10.1038/s43856-025-00887-7
Communications Medicine · Nature Portfolio (2025)

Myocardial infarction admissions and in-hospital mortality rise on geomagnetic disturbance days (Brazil nationwide data)

Nationwide hospital dataset demonstrating age- and sex-stratified increases in cardiac admissions on geomagnetically disturbed days.

Boundary: Ecological design; controls for temperature, though individual lifestyle habits remain unmeasured.
Grade B · Multi-City Cohort https://doi.org/10.1038/s43856-025-00822-w
Communications Medicine · Nature Portfolio (2025)

Blood-pressure fluctuations track geomagnetic activity in Qingdao & Weihai cohorts, independent of temperature and PM2.5

Isolates an independent statistical link between geomagnetic activity and systolic/diastolic blood pressure after controlling for temperature and PM2.5.

Boundary: Mean shift is subtle (1–3 mmHg) and easily buffered in healthy adults.
Grade B · Bio-Signal Telemetry https://doi.org/10.3390/atmos16020219
Atmosphere · MDPI (2025)

Human heart rate rhythms synchronize with millihertz (mHz) geomagnetic oscillations during storm recovery (61 ECGs)

Long-duration ECG telemetry showing phase-synchrony between autonomic heart rate rhythms and ambient mHz magnetic pulsations.

Boundary: Small volunteer cohort (n=61); reflects physiological adaptation rather than arrhythmia.
Grade B · HRV Adaptation Study https://doi.org/10.3390/atmos14121707
Atmosphere · MDPI (2023)

Higher resting heart rate variability (HRV) predicts stronger physiological resilience during geomagnetic storms

Explains why sensitivity varies: robust baseline vagal tone (HRV) acts as an autonomic buffer against geomagnetic stress.

Boundary: Sleep debt, caffeine, and stress impact HRV far more than space weather.
Grade C · Mechanistic Hypothesis https://doi.org/10.3390/ijerph17093083
Int. J. Environ. Res. Public Health (2020)

Exploratory pineal melatonin, circadian rhythm, and magnetoreception pathways in geomagnetic bio-sensitivity

Maps candidate pathways (retinal cryptochromes and pineal melatonin modulation) while emphasizing individual clinical proof remains open.

Boundary: Hypothesis-level pathway; never proves a solar flare caused your headache.
Medical Boundary: Population correlations never imply individual medical causation. If experiencing chest pain or acute symptoms, seek emergency medical care immediately.

Clinical Evidence Frequently Asked Questions

Why are studies separated into Grade A, Grade B, and Grade C?

To prevent early hypotheses from being overstated as clinical proof, Grade A covers systematic reviews across multi-million-person cohorts, Grade B covers multi-city blood-pressure and continuous ECG cohorts, and Grade C covers exploratory melatonin and cryptochrome hypotheses.

Does population relative risk (RR 1.3–1.5) mean a storm will make me sick tonight?

No. Population relative risk reflects statistical admission shifts in clinically vulnerable groups during severe storms; healthy adults buffer subtle 1–3 mmHg blood pressure shifts naturally. Use Blind Check-in on the workspace to measure your personal 30-day correlation.

How are these 7 peer-reviewed studies verified?

Every study in this library is programmatically verified against the official Crossref API for valid DOI resolution, journal metadata, and publication year during our automated build gate.
