CPAP therapy is highly effective for obstructive sleep apnea — when people use it. Studies consistently find 30-50% of CPAP users discontinue within a year. The mask discomfort, noise, claustrophobia, and travel challenges are real barriers that deserve real alternatives. Here’s what the evidence actually shows, ranked by effectiveness.
First: Know Your Apnea Severity
Apnea severity is measured by the Apnea-Hypopnea Index (AHI) — breathing disruptions per hour. Mild: 5-15. Moderate: 15-30. Severe: 30+. The appropriate alternative depends heavily on your AHI. Know your number before evaluating alternatives. Our guide on sleep apnea symptoms covers the diagnostic pathway.
What Actually Works
Oral Appliance Therapy — Best Alternative: Custom-fitted mandibular advancement devices reposition the lower jaw forward, keeping the airway open mechanically. Multiple RCTs show MADs are effective for mild-to-moderate sleep apnea with AHI reductions of 50-60% on average. Custom-fitted devices from sleep dentists ($1,000-3,000) have much stronger evidence than over-the-counter boil-and-bite versions. Covered by many insurance plans.
Positional Therapy: Many people have apnea primarily when sleeping on their back. Preventing supine sleep reduces AHI by 50%+ in positional apnea patients. Commercial devices like Night Shift have clinical evidence; tennis ball in the back of a sleep shirt is the DIY version.
Weight Loss: A 10% weight reduction reduces AHI by approximately 26% on average. The only intervention addressing the underlying cause rather than compensating for it.
Hypoglossal Nerve Stimulation (Inspire): Increasingly covered by insurance for CPAP-intolerant patients with appropriate anatomy. Much stronger evidence than older surgical approaches.
What Doesn’t Work
Anti-snoring pillows, chin straps, nasal strips, and most OTC devices have little or no evidence for actual apnea treatment. Chin straps may help with mouth-breathing snoring — a different problem addressed in our snoring remedies guide.
