As an integrative airway dental practice, we have seen firsthand the profound impact that proper nasal breathing can have on overall health. Central to this discussion is nasal nitric oxide (nNO), a remarkable molecule produced in the paranasal sinuses and released during nasal breathing. Understanding the importance of nasal nitric oxide can transform our approach to breathing and health, highlighting why nasal breathing should be prioritized over mouth breathing.
Enhanced Oxygen Uptake in the Blood
One of the most critical roles of nasal nitric oxide is its ability to enhance the amount of oxygen uptake in the blood. When we breathe through our nose, the nitric oxide is carried into the lungs, where it helps to dilate the blood vessels in the alveoli, the tiny air sacs where gas exchange occurs. This dilation allows for more efficient transfer of oxygen from the air into the bloodstream. Studies have shown that nasal breathing can increase oxygen uptake in the blood by approximately 10% compared to mouth breathing. This increase is not just a minor benefit; it can significantly impact physical performance, cognitive function, and overall vitality.
Redistributing Blood Flow in the Lungs
Nasal nitric oxide also plays a crucial role in optimizing blood flow within the lungs. It helps to redistribute blood flow to the areas of the lungs that are most efficiently ventilated. This means that the parts of the lungs that are receiving the most air also receive the most blood flow, which maximizes the efficiency of gas exchange. This optimized redistribution is crucial for maintaining healthy lung function and ensuring that the body gets the maximum possible oxygen from each breath.
First Line of Defense Against Pathogens
Beyond its role in oxygenation, nasal nitric oxide is a critical component of the body’s immune defense system. nNO possesses potent antimicrobial properties, acting as a first line of defense against airborne pathogens. When we breathe through our nose, the nitric oxide released into the nasal passages helps to neutralize bacteria, viruses, and other harmful microorganisms before they can reach the lungs and cause infection. This natural defense mechanism is particularly important in today’s world, where respiratory infections are a significant concern.Integrative Approach to Breathing
At Santa Teresa Smiles we emphasize the importance of nasal breathing not just for its immediate benefits, but also for its long-term impact on health. We encourage patients to adopt nasal breathing which leads to improved sleep quality, reduced snoring and sleep apnea symptoms, and better overall respiratory health. Techniques such as myofunctional therapy, which strengthens the muscles of the tongue and throat, support the transition to nasal breathing and help maintain it.
Nasal nitric oxide is a powerhouse molecule that plays a vital role in enhancing oxygen uptake, optimizing blood flow in the lungs, improving oxygenation, and defending against pathogens. As we continue to explore and understand the benefits of nasal breathing, it becomes increasingly clear that this simple practice can have profound effects on our health and well-being. By prioritizing nasal breathing, we can harness the power of nasal nitric oxide and breathe our way to better health.
