Five parts of Health Intelligence
Research Library
Plain-language study summaries with evidence labels, limitations, and primary sources.
Browse the library →Conditions & Treatments
Focused condition pages that separate claims, evidence, and uncertainty — not a full medical encyclopedia.
Open conditions →Clinical Trials & Biomarkers
How to read trial listings and biomarker signals without treating them as personal advice.

Reviewed briefs Sonic Vitality can reuse
Guides and hubs show these cards; the claim stays owned by Research. Product pages never become the source of a health claim.
Evidence Brief Evidence: Supported — Controlled-chamber particle-removal data from a federal research program is strong for the engineering claim (DIY cleaners clean air effectively); it does not by itself establish health-outcome benefits in homes.
EPA chamber testing: DIY box-fan air cleaners removed wildfire-smoke particles at rates comparable to commercial purifiers
Box-fan air cleaners built with MERV-13 filters produced clean-air delivery for smoke-sized particles comparable to commercial portable HEPA purifiers, at a fraction of the purchase price; multi-filter (CR box) designs outperformed single-filter designs, and fan-motor temperature testing found no fire-safety concern with filters attached.
Evidence Brief Evidence: Emerging — The core mechanism claim (entrainment) has genuinely mixed direct evidence — neither confirmed nor refuted.
Systematic review finds inconsistent EEG evidence for binaural-beat brainwave entrainment
Roughly half of the reviewed EEG studies reported evidence consistent with brainwave entrainment during binaural-beat stimulation and half did not; methodological differences (carrier frequency, beat frequency, exposure time, masking) plausibly explain the split.
Evidence Brief Evidence: Supported — Large, long, well-conducted cohort with dose-response — strong observational evidence, but not causal proof.
Frequent sauna bathing associated with lower cardiovascular and all-cause mortality in Finnish men
Compared with one sauna session per week, 4–7 sessions per week were associated with roughly 50% lower risk of fatal cardiovascular events and ~40% lower all-cause mortality over ~20 years of follow-up, with a dose-response pattern for both frequency and session length.
Evidence Brief Evidence: Emerging — A pooled positive effect exists, but heterogeneity, blinding problems, and protocol dependence keep this promising rather than established.
Meta-analysis finds small-to-moderate effects of binaural beats on anxiety, attention, and pain
Binaural-beat exposure showed a small-to-moderate pooled effect (g ≈ 0.45) across memory, attention, anxiety, and pain-perception outcomes, with longer exposure and beat presentation before/during tasks appearing more effective.

Public communities are idea signals only. Claims reach this hub after they are traced to a primary source and given an evidence label.
