Breathing and throat exercises can meaningfully reduce sleep apnea severity, cutting the number of breathing interruptions per hour by roughly 50% in adults. That’s a significant improvement, though it comes with important caveats about who benefits most and what kind of exercises actually work. The exercises that help aren’t the deep-breathing relaxation techniques you might picture. They’re targeted movements that strengthen the muscles in your throat, tongue, and airway.
How Throat and Mouth Exercises Reduce Apnea
Obstructive sleep apnea happens when the soft tissues in your upper airway collapse during sleep, blocking airflow. The muscles that hold your airway open relax too much, and gravity does the rest. Throat and mouth exercises, formally called myofunctional therapy or oropharyngeal exercises, work by strengthening those specific muscles so they’re better at keeping your airway open while you sleep.
Think of it like physical therapy for the inside of your throat. You’re training your tongue, soft palate, and the walls of your pharynx to maintain tone even during sleep. A systematic review and meta-analysis published in the journal Sleep found that adults who practiced these exercises for at least three months reduced their apnea-hypopnea index (the number of times breathing stops or becomes shallow per hour) from an average of about 25 events per hour down to around 13. That 50% reduction is clinically meaningful. In children, the results were even more pronounced, with a 62% reduction.
One study also found that in people with moderate apnea, these exercises reduced neck circumference, which correlated with fewer breathing interruptions. A thicker neck puts more pressure on the airway, so even small reductions in tissue bulk around the throat can help.
What the Exercises Actually Look Like
The exercises that have evidence behind them target four main areas: your tongue, soft palate, throat walls, and facial muscles. Common exercises include pressing your tongue firmly against the roof of your mouth and sliding it backward, pronouncing certain vowel sounds repeatedly to engage the throat muscles, and practicing forceful swallowing patterns. These aren’t complicated movements, but they need to be done consistently.
A typical routine takes about 10 minutes, split into two five-minute sets performed twice daily. Most studies showing real improvement required at least three months of consistent daily practice before significant changes appeared in sleep study results. This is a long-term commitment, not a quick fix.
Beyond structured exercises, some activities that work the same muscles have shown results. A randomized controlled trial published in the BMJ tested didgeridoo playing in people with moderate sleep apnea. Participants practiced about 25 minutes a day, nearly six days a week, for four months. The didgeridoo group had significantly less daytime sleepiness, and their partners reported less disruption from snoring. The circular breathing technique required to play the instrument engages the entire vocal tract, training the lips, tongue, cheeks, and throat muscles simultaneously. The researchers noted that the collapsibility of participants’ upper airways measurably decreased. Singing and playing other wind instruments may offer similar, though less studied, benefits.
Other Types of Breathing Retraining
A review of 14 studies found that several different breathing approaches can improve sleep apnea beyond just throat exercises. These include the Buteyko method (which focuses on nasal breathing and reducing breathing volume), inspiratory resistance training (breathing in against a device that creates resistance, like a workout for your breathing muscles), and diaphragmatic breathing techniques.
Inspiratory and expiratory muscle training use handheld devices that make you work harder to breathe in or out, gradually building strength. One small study found that five weeks of expiratory muscle training improved apnea severity in people with mild to moderate cases. However, another study using inspiratory muscle training for 12 weeks found improvements in snoring, fatigue, and sleep quality but no significant change in the actual number of apnea events. The results are mixed, and these approaches seem most helpful for people who have minimal anatomical obstruction and already have some degree of breathing dysfunction during the day.
Where Exercises Fall Short
Sleep apnea severity is measured by the apnea-hypopnea index: 5 to 14 events per hour is mild, 15 to 29 is moderate, and 30 or more is severe. Breathing exercises show the most consistent benefit for mild to moderate cases. If your airway is collapsing 30 or more times an hour, muscle strengthening alone is unlikely to solve the problem. The structural deficit is simply too large for toned muscles to overcome.
Even the 50% reduction seen in studies still left many adult participants with an average of about 13 events per hour, which falls in the mild apnea range. That’s a real improvement in symptoms and health risk, but it’s not a cure. For people with severe apnea or significant anatomical factors like a very narrow airway, large tonsils, or obesity, CPAP (a machine that keeps the airway open with air pressure) remains the primary treatment.
Combining Exercises With CPAP
One of the most practical findings is that throat exercises and CPAP work well together. A study found that people who combined myofunctional therapy with CPAP used their CPAP machines more consistently than those using CPAP alone. This matters because CPAP only works when you actually wear it, and adherence is one of the biggest challenges in sleep apnea treatment. Many people find CPAP uncomfortable and skip nights, which undermines the therapy.
A network meta-analysis comparing different treatment combinations found that pairing CPAP with inspiratory muscle training improved sleep quality more than CPAP by itself. The exercises don’t replace the machine, but they appear to make the overall treatment experience better and help people stick with it. Strengthening your airway muscles may also allow for lower CPAP pressure settings over time, making the device more comfortable to use.
Getting Started
If you have mild to moderate sleep apnea and want to try this approach, the most evidence-backed option is oropharyngeal (myofunctional) exercises performed consistently for at least three months. A speech-language pathologist or myofunctional therapist can teach you the specific movements and make sure you’re targeting the right muscles. Some sleep clinics now offer this as part of their treatment programs.
For people already on CPAP who struggle with adherence, adding throat exercises is a low-risk way to potentially improve comfort and compliance. For those with mild apnea who want to avoid a machine altogether, exercises represent a reasonable first-line approach, with the understanding that consistent daily practice is non-negotiable and results take weeks to months to appear. A follow-up sleep study after three to six months of practice is the only way to know whether the exercises are making a measurable difference in your case.
