Why is it Easier to Breathe Through My Mouth Than My Nose?
The body naturally chooses the easiest way to get air. When breathing through the nose feels difficult, restricted, or simply doesn't feel satisfying, mouth breathing can become the body's preferred habit—even during sleep. Congestion, a deviated septum, difficulty keeping the lips together, and inefficient breathing patterns can all contribute.
How Can Orofacial Myofunctional Therapy Help?
Therapy helps address the functional barriers to comfortable nasal breathing. Through targeted exercises, improved lip closure, breathing practice, habit development, and subconscious retraining, Orofacial Myofunctional Therapy helps make nasal breathing easier, more comfortable, and more automatic—during the day and throughout sleep.
Signs of Mouth Breathing in Adults and Children
Mouth breathing isn't always obvious. Some people breathe through their mouths throughout the day, while others only notice it during sleep. Recognizing the signs can help identify breathing habits that may be affecting everyday comfort, sleep, and oral function.
Mouth Breathing in Adults
Difficulty breathing comfortably through the nose, lips that fall open when relaxed, dry mouth upon waking, overnight mouth breathing, snoring, heavy breathing during sleep, restless sleep, nighttime teeth clenching or grinding, waking tired, daytime fatigue, brain fog, memory difficulties, or difficulty concentrating.
Mouth Breathing in Children
Sleeping with the mouth open, snoring, heavy breathing, drooling, restless sleep, moving around frequently in bed, difficulty keeping the lips together, waking tired despite a full night's sleep, difficulty concentrating, becoming easily frustrated, restless or unfocused energy, dental crowding, or concerns about facial growth and development.
Mouth breathing, snoring, and heavy breathing during sleep can be associated with obstructive sleep apnea (OSA) and Upper Airway Resistance Syndrome (UARS). As the body relaxes during sleep, reduced muscle tone can contribute to airway narrowing. Orofacial Myofunctional Therapy works to improve the strength, tone, coordination, and function of the tongue and surrounding orofacial muscles, while developing more automatic oral posture and breathing habits that may help support airway stability during sleep. Therapy can complement medical treatment for sleep-disordered breathing.

Yes, Orofacial Myofunctional Therapy can still help. Therapy retrains breathing patterns, supports diaphragmatic breathing, encourages more efficient airflow, and improves the muscle function and habits that support comfortable nasal breathing. Many people are surprised to learn that congestion is often only one piece of the puzzle. Muscle function, lip closure, oral posture, breathing habits, and airway use can also influence nasal breathing.
Yes, Orofacial Myofunctional Therapy can still be beneficial. A deviated septum does not automatically mean nasal breathing is impossible. While a septal deviation may contribute to resistance in the nose, breathing habits, congestion, muscle function, lip closure, and oral posture also play important roles. Therapy helps address these factors to support more comfortable and sustainable nasal breathing.
Keeping the lips closed comfortably is about more than willpower. If breathing through the nose does not feel comfortable or satisfying, the lips fatigue easily, or the muscles that support the lips and jaw are not functioning efficiently, the mouth may naturally fall open. Orofacial Myofunctional Therapy helps improve breathing patterns, lip closure, muscle function, and habit formation so that keeping the lips closed becomes easier, more comfortable, and more automatic—during the day and throughout sleep.
During sleep, the body gradually relaxes and conscious control disappears. As sleep deepens, breathing relies less on effort and more on muscle tone, airway function, and subconscious habits. Lips that stay closed easily during the day may fall open at night if the muscles that support the lips, jaw, and airway are not functioning efficiently. Some people also notice congestion, sinus pressure, or post-nasal drip only after lying down, making nasal breathing more difficult than it feels during the day. Orofacial Myofunctional Therapy helps retrain the muscles and subconscious habits that support comfortable nasal breathing, helping it become easier to maintain throughout the night.
Mouth breathing is rarely a simple willpower problem. If breathing through the nose does not feel comfortable or satisfying, the lips do not stay closed easily, congestion is present, or the muscles and habits that support nasal breathing have not been developed, the body will naturally return to the easiest way to get air. Simply trying harder often isn't enough. Orofacial Myofunctional Therapy helps address the physical and functional factors that may be contributing to mouth breathing while using repetition, habit development, and subconscious retraining to help make nasal breathing easier, more comfortable, and more automatic over time.
Mouth taping can be a useful training tool, but it is rarely the entire solution. If breathing through the nose does not feel comfortable, congestion is present, the lips do not stay closed easily, or the habits that support nasal breathing have not been developed, the tape may not stay on throughout the night and mouth breathing often returns once the tape is removed.
Orofacial Myofunctional Therapy helps make nasal breathing more comfortable, improves lip closure, and develops the subconscious habits needed to maintain nasal breathing during the day and throughout sleep. The goal is to use tape as a tool—not rely on it forever—and instead make nasal breathing natural and sustainable.
Yes. While breathing habits become deeply ingrained over time, the body continues to adapt throughout life. Many adults assume they are too old to change, but nasal breathing, lip closure, muscle function, and breathing habits can all improve with consistent practice. Orofacial Myofunctional Therapy uses targeted exercises, habit development, and subconscious retraining to help make nasal breathing easier, more comfortable, and more automatic over time.
Yes. Persistent mouth breathing during sleep is not something most children simply outgrow. Children who regularly sleep with their mouth open may also snore, drool, wake restless, grind their teeth, struggle to keep their lips closed during the day, have difficulty concentrating, or appear tired despite getting a full night's sleep. Over time, chronic mouth breathing may influence facial growth and development, contributing to dark circles under the eyes, a longer and narrower facial appearance, a high vaulted palate, and dental crowding.
The earlier mouth breathing is identified, the greater the opportunity for change. Children are still growing and developing, making them especially responsive to intervention. Orofacial Myofunctional Therapy helps improve breathing habits, support healthy muscle function and facial development, and establish comfortable nasal breathing patterns that can positively influence growth, sleep, and overall function for years to come.
Yes. Young children are often the easiest to help because their habits, muscles, and growing facial structures are still developing. With parent involvement and consistent practice, Orofacial Myofunctional Therapy uses age-appropriate exercises, games, and habit-building strategies to help make nasal breathing natural, comfortable, and sustainable. The earlier healthy breathing habits are established, the greater the opportunity to positively influence growth, sleep, breathing, and overall function.
