Breathing & Sleep

What nasal spray do myofunctional therapists recommend?
In our clinical practice, we most commonly recommend xylitol-based nasal sprays — including Xlear for adults and Xlear Kids for children — and propolis plus xylitol formulas for immune and sinus support. These are drug-free, non-habit-forming, and support the nasal microbiome without the rebound effects of medicated sprays. They are a foundational tool for patients working to shift from mouth breathing to consistent nasal breathing.

Can supplements help with mouth breathing and sleep?
Supplements cannot correct the underlying muscle dysfunction that drives mouth breathing — that requires myofunctional therapy. However, they can meaningfully support the nervous system and sleep quality while patients are doing the clinical work. Magnesium is one of the most commonly recommended supplements in our practice for sleep-disordered breathing patients, supporting muscle relaxation, nervous system regulation, and deep sleep. Glycine is another evidence-supported option for sleep quality optimization.

What is SOVT breathing and how does it help airway function?
SOVT stands for Semi-Occluded Vocal Tract — a category of breathing exercises that create resistance in the airway to strengthen the muscles involved in breathing and voicing. In myofunctional therapy, SOVT tools are used to activate the tongue base, improve lip seal, and build the muscle coordination necessary for consistent nasal breathing. The airflow training tools in this collection are selected specifically for this application.

What is the best natural sleep supplement for nervous system support?
In our clinical practice, the most commonly recommended foundational supplements for nervous system support and sleep quality are magnesium — particularly magnesium glycinate or magnesium malate forms — and glycine powder. For children, we frequently recommend gentle magnesium formulas and omega-3 fatty acids. These supplements support the nervous system regulation that is often disrupted in patients with airway dysfunction and sleep-disordered breathing.

How do I support nasal breathing at home between therapy sessions?
The most effective home strategies include daily use of a xylitol nasal spray to keep nasal passages clear, consistent practice of the oral motor and breathing exercises assigned by your clinician, and using airway training tools such as SOVT devices as directed. Environmental support — including eucalyptus shower vapors and breathe-blend essential oil rollers — can help reinforce the nasal breathing habit as part of a daily routine.

Is mouth breathing in adults treatable?
Yes — myofunctional therapy has strong clinical evidence for improving nasal breathing patterns in adults. The process involves identifying and addressing the root causes of mouth breathing, retraining the muscles of the tongue, lips, and airway, and establishing new functional habits. The products in this collection are selected to support that process at home, alongside formal clinical intervention.

What is the difference between a xylitol nasal spray and a medicated nasal spray?
Medicated nasal sprays — including oxymetazoline and similar decongestants — work by constricting blood vessels to reduce swelling. They are effective short-term but cause rebound congestion with regular use and are not recommended for daily nasal hygiene. Xylitol nasal sprays work differently: xylitol inhibits bacterial adhesion in the nasal passages, supports the nasal microbiome, and helps maintain moisture without any rebound effect. They are safe for daily use in adults and children and are the type we recommend most frequently in clinical practice.
