Four parts of Health Intelligence
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: Established — A formal evidence synthesis by a major public-health body, consistent with a large observational literature.
WHO guidelines identify environmental noise as a significant public-health risk
Chronic exposure to environmental noise above recommended levels is associated with sleep disturbance, annoyance, and increased risk of ischaemic heart disease; WHO issues exposure-limit recommendations for road, rail, aircraft, wind-turbine, and leisure noise.
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.
Evidence Brief Evidence: Supported — A controlled human experiment with physiological endpoints, consistent with larger observational literature on light at night — but small and short.
Light exposure during sleep associated with cardiometabolic effects and impaired sleep physiology
One night of sleeping in moderate room light (100 lux) versus dim light (<3 lux) increased nighttime heart rate, decreased heart-rate variability, and increased next-morning insulin resistance.

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