Are Endless Respiratory Infections in Your Child Caused by Oral Breathing?
As the weather turns colder, parents brace themselves for yet another season of relentless colds, viruses, and sleepless nights with a child, all while missing out on kindergarten or school. In the quest to combat these persistent illnesses, many turn to various remedies such as supplements, syrups, salt rooms, and medication. However, amidst these efforts, one significant factor is often overlooked – oral breathing.
Oral breathing can significantly impact a child’s susceptibility to respiratory infections because it disrupts the natural process of nasal breathing, which is designed to filter, humidify, and warm the air before it reaches the lungs. This protective mechanism is compromised when a child breathes through their mouth, leading to dried mucous membranes and reduced saliva and nitric oxide production.
These disruptions weaken the body’s defenses, making it easier for harmful bacteria and viruses to enter the respiratory system.
Oral Breathing Dries Out Saliva and Bypasses the Mucous Membranes of the Nose
The nasal passages are equipped with a sophisticated system of filters, including tiny hairs called cilia and mucous membranes. These components work together to trap pathogens, dust, and other airborne particles, preventing them from reaching the lungs. Additionally, the nose warms and humidifies the air, making it more comfortable for the lungs and reducing the risk of irritation or infection.
When a child breathes through their mouth, they bypass these crucial defense mechanisms. The constant airflow through the mouth dries out the mucous membranes, making them less effective at trapping and filtering harmful particles.
By drying out the mouth and throat, mouth breathing also reduces saliva production.
Saliva contains powerful enzymes and antibodies, such as lysozyme and immunoglobulin A (IgA), which help neutralize harmful bacteria and viruses. Last but not least, saliva helps maintain the pH balance in the mouth, preventing harmful bacterial overgrowth that can spread to the respiratory system.
The Importance of Nitric Oxide in Nasal Breathing
Oral breathing also impacts the production of nitric oxide, a gas with many important roles in the body.
Nitric oxide helps dilate blood vessels and bronchi, enhancing circulation and improving breathing. It also has antimicrobial properties and supports oxygen exchange in the lungs. Mouth breathing significantly reduces nitric oxide production, which increases the risk of infections and weakens the immune response.
Nasal breathing is essential for maintaining adequate nitric oxide levels and ensuring that natural defence mechanisms such as air filtration, pathogen capture, and the enhancement of immune function work properly.
What Can Cause Mouth Breathing
Mouth breathing in children can stem from various factors. Common colds and sinus infections often lead to nasal congestion, which may force a child to breathe through their mouth. Persistent nasal congestion, if not properly addressed, can turn mouth breathing into a habitual pattern.
Allergies are another significant cause of mouth breathing. Exposure to allergens such as pollen, dust, or pet dander can inflame and block nasal passages, making it difficult for children to breathe through their nose.
Anatomical issues, such as enlarged adenoids or tonsils, can also obstruct nasal airflow, prompting children to rely on mouth breathing.
Dental and orthodontic issues, including malocclusion or misalignment of the teeth and jaw, can restrict airway space and contribute to mouth breathing.
Similarly, a high palate or poor tongue posture can affect nasal breathing. TMJ disorders, affecting the temporomandibular joint, can lead to mouth breathing due to discomfort or misalignment.
Which Doctor Can Help Your Child Avoid Oral Breathing?
To address mouth breathing in children, it is essential to identify its underlying causes. Typically, the problem falls within the realms of ENT or dental medicine.
Ear, nose, and throat (ENT) specialists assess the nasal passages and throat for structural issues, such as enlarged adenoids or tonsils, that may obstruct airflow. They conduct detailed examinations and recommend treatments ranging from medication to surgery, depending on the severity of the obstruction.
Functional dentists evaluate dental and orthodontic issues that may contribute to mouth breathing, such as malocclusion or misalignment of the teeth and jaws. They provide treatments and other interventions to correct these issues, improving both the function and comfort of the child’s oral and respiratory systems.
In cases where mouth breathing becomes a habit, even after addressing the initial cause, myofunctional therapists can help. They focus on retraining oral and facial muscles to promote proper breathing habits. Through specialized exercises and behavioral techniques, they help children develop and reinforce nasal breathing patterns, supporting long-term respiratory health.
Parents’ Role in Encouraging Nasal Breathing at Home
Parents can promote nasal breathing by encouraging good posture, keeping the nose clean, reminding children to keep their lips closed during activities, and monitoring sleep patterns. Teaching children breathing exercises with a licensed breathwork expert can also help them master proper breathing and self-correct when they resort to oral breathing.
Children who breathe properly through their noses are less likely to suffer from respiratory infections, resulting in better academic performance, mood regulation, and overall health.
