Select interventions to build a combined therapy stack. Verified against NBC News expert reporting.

🦷

Mandibular Mouthpiece (MAD)

Mechanically shifts lower jaw 3-6mm forward, enlarging retroglossal airway space.

High Target Plausibility

📐

Wedge Pillow (30° Incline)

Elevates upper torso to minimize gravitational airway narrowing and pharyngeal collapse.

Moderate Plausibility

👃

Nasal Dilator Strips

Spring-like bands widen anterior nasal valve, reducing negative inspiratory pressure.

Source Grounding: Based on clinical reporting via NBC News & @nbcselected on OTC anti-snoring efficacy. Mandibular advancement devices (MADs) provide robust retroglossal expansion; wedge pillows alleviate gravitational supine collapse; nasal dilators lower nasal resistance when congestion is present.
