LA CATAORA

A good night’s sleep is one of the pillars of good health. Yet, for millions of people, restful sleep remains elusive, disrupted by snoring, restlessness, and frequent waking. While many factors can contribute to poor sleep, a surprising culprit is often hiding in plain sight: the way we use the muscles of our mouth and face. This is where myofunctional therapy, a specialised form of physical therapy for the mouth, tongue, and facial muscles, comes into play.

This therapy is gaining recognition for its profound impact on breathing patterns, particularly during sleep. Addressing dysfunctional oral habits can help resolve issues that contribute to snoring and sleep-disordered breathing, including sleep apnoea. This article examines the intricate relationship between our oral muscles, breathing, and sleep quality, and reveals how myofunctional therapy provides a non-invasive approach to quieter, more restful nights.

Understanding the Orofacial Complex: More Than Just a Mouth

To understand how myofunctional therapy works, we first need to grasp the concept of the «orofacial complex.» This term refers to the intricate system of muscles in the mouth, jaw, and face. These muscles are responsible for essential functions like chewing, swallowing, speaking, and, most importantly, breathing.

For optimal health, these muscles should work in harmony with one another. This includes maintaining proper oral rest posture:

• Lips: Gently sealed without straining.
• Teeth: Slightly apart, not clenched.
• Tongue: Resting gently against the roof of the mouth (the palate), just behind the front teeth.

When this posture is compromised, a cascade of problems can begin. An incorrect tongue position, for instance, is one of the most common myofunctional disorders.

The Link Between Tongue Posture, Breathing, and Sleep

The position of your tongue at rest is more critical than you might think. When the tongue rests correctly on the palate, it acts as a natural support system for the upper airway, helping to keep it open and clear.

However, many people have what is known as a «low tongue posture,» where the tongue rests on the floor of the mouth. This can occur due to habits formed in childhood, such as thumb-sucking, prolonged pacifier use, or chronic nasal congestion from allergies that lead to mouth breathing.

When the tongue rests low, it tends to fall back towards the throat, especially when you are lying down to sleep. This narrows the airway, creating a bottleneck through which air must pass. As air is forced through this smaller space, it causes the soft tissues in the throat to vibrate, producing the sound we know as snoring.

In more severe cases, the tongue can fall back far enough to completely block the airway. This causes a pause in breathing, an event known as an apnoea. The brain senses the lack of oxygen and sends a panic signal to wake the body up just enough to resume breathing, often with a gasp or snort. When this happens repeatedly throughout the night, it is diagnosed as obstructive sleep apnoea (OSA), a serious condition linked to high blood pressure, heart disease, and daytime fatigue.

How Myofunctional Therapy Helps

Myofunctional therapy is essentially a workout programme for your face and mouth. It involves a series of customised exercises designed to correct poor muscle habits and retrain the orofacial complex to function correctly. A trained myofunctional therapist works with you to achieve several key goals that directly impact sleep and breathing.

1. Re-establishing Correct Tongue Posture

The primary goal is to train the tongue to rest naturally on the roof of the mouth, or the palate. Exercises focus on strengthening the tongue muscles and improving their coordination, so the correct posture becomes second nature, even during sleep. When the tongue is properly positioned, it provides structural support to the airway, thereby reducing the likelihood of collapse.

2. Promoting Nasal Breathing

Humans are designed to be nasal breathers. The nose warms, filters, and humidifies the air we breathe, preparing it for the lungs. Mouth breathing bypasses this natural filtration system and contributes to a low tongue posture. Myofunctional therapy includes exercises to encourage a proper lip seal and promote nasal breathing, both during the day and at night. Consistent nasal breathing helps stabilise the airway and improve oxygen saturation.

3. Strengthening Pharyngeal Muscles

The therapy does not just focus on the tongue. It also involves exercises that tone the muscles of the soft palate, throat (pharynx), and face. Weak, flabby muscles in the airway are more prone to collapsing during sleep. By strengthening these tissues, myofunctional therapy makes them firmer and more resistant to vibration and collapse. This can significantly reduce the severity of both snoring and sleep apnoea.

4. Correcting Swallowing Patterns

Another common issue is an incorrect swallowing pattern, often referred to as a «tongue thrust,» where the tongue pushes forward against the teeth during swallowing. This pattern reinforces a low and forward tongue position. Through targeted exercises, targeted exercises retrain the swallowing reflex, encouraging the tongue to press up against the palate instead. This proper swallow further reinforces the correct oral rest posture.

Who Can Benefit from Myofunctional Therapy?

Myofunctional therapy is a valuable treatment for a wide range of individuals, including:

• Snoring: For many, snoring is the first and most obvious sign of a compromised airway. Myofunctional therapy can be a highly effective treatment for reducing or even eliminating snoring by toning the muscles of the airway.
• Obstructive Sleep Apnoea (OSA): While CPAP (Continuous Positive Airway Pressure) is the gold standard for severe OSA, recent findings show that oral myofunctional therapy can serve as an effective adjunct treatment.

• Obstructive Sleep Apnoea (OSA): While CPAP (Continuous Positive Airway Pressure) is the gold standard for severe OSA, myofunctional therapy is recognised as an effective adjunct treatment. Studies have shown it can significantly reduce the Apnoea-Hypopnoea Index (AHI), a measure of sleep apnoea severity. For some individuals with mild to moderate OSA, it may even serve as a standalone therapy.
• Children with Sleep-Disordered Breathing: Early intervention in children can be particularly effective. Correcting poor oral habits and promoting proper facial development can prevent more serious sleep and breathing issues later in life.
• Individuals Who Struggle with CPAP: Many people find it difficult to tolerate wearing a CPAP mask. Myofunctional therapy can improve their ability to use CPAP or, in some cases, reduce their dependency on it.

The Treatment Process: A Commitment to Change

Myofunctional therapy is not a passive treatment. It requires active participation and commitment from the patient. A therapist will design a personalised exercise plan, which you will need to practise daily.

The process typically begins with a comprehensive evaluation to identify your specific myofunctional disorders. Based on this assessment, your therapist will guide you through exercises, meeting with you regularly to monitor your progress and introduce new exercises as you advance. While it requires dedication, the results can be life-changing, offering a natural and empowering way to enhance your overall well-being.

A Path to Better Sleep and Breathing

The connection between facial muscles, breathing, and sleep is undeniable. Dysfunctional oral habits that seem minor can have a major impact on our ability to breathe efficiently at night, leading to snoring, fragmented sleep, and serious health conditions like sleep apnoea.

Myofunctional therapy offers a logical and effective solution by addressing the root cause of the problem: weak and uncoordinated orofacial muscles. By retraining your tongue, promoting nasal breathing, and strengthening your airway, this targeted therapy helps restore the natural harmony of your body. It is a powerful tool for anyone seeking to reclaim quiet, restful nights and improve their overall health and well-being.
