The papers that informed this month's Jawra updates — the methodology we trusted, the methodology we didn't, and what changed in the app as a result.
New 18-month longitudinal data on tongue-up resting posture and inter-molar palate distance in children aged 6–11. We shifted the foundational tongue-posture routine from 2× to 3× daily for under-12 users based on the effect-size delta.
Graded CO₂-tolerance work led to a 38% reduction in nighttime mouth-open events at 6 weeks. We added an evening "ladder" variant and tuned the breath-hold cap.
Compelling pooled effect on heart-rate variability and reported migraine intensity. We updated the in-app hum guide to target the 100–110Hz band with real-time pitch feedback.
Three weeks of camera-cued chin retraction reduced reported jaw-load by a clinically meaningful margin. Drove the new posture-cue overlay in the iOS build.
