While breathing is something we tend to do unconsciously, it's not that common for individuals to ever sit down and reflect on how the way one breathes, the nose or the mouth can actually affect overall well-being. Cardiac surgeon Dr. Jeremy London recently addressed the subject in a social media clip, where he explained the science behind why breathing through the nose is significantly better than breathing orally. From enhancing oxygen uptake to soothing the nervous system, nasal breathing is essential in aiding physical and mental well-being.
One of the lesser-known but potent advantages of nasal breathing is stimulating the production of nitric oxide, an important molecule produced in the nasal passages. This molecule encourages the opening of blood vessels, leading to improved circulation and more effective transport of oxygen and nutrients to the body. Enhanced circulation not only ensures proper nourishment of tissues but also aids in keeping blood pressure healthy. This critical process is circumvented when you inhale through the mouth, bypassing nitric oxide's protective effects on the heart.
Dr. Jeremy emphasizes that the body becomes far more efficient at oxygen intake when you breathe through your nose. The nasal passages retard and warm the air, providing the lungs with more time to absorb additional oxygen.
This reduces the workload on the heart, which does not have to pump as hard to supply oxygenated blood. In the long run, this can lead to increased stamina, increased energy, and less strain on the cardiovascular system.
A second important benefit of breathing through the nose is the way that it automatically engages the parasympathetic nervous system, otherwise known as the "rest and digest" mode. Stimulating this system causes the body to relax by decreasing the heart rate and blood pressure. Conversely, mouth breathing is commonly associated with the sympathetic nervous system, which governs the body's "fight or flight" response and maintains it in a state of tension. Breathing through the nose can be an invitation to calmness and emotional balance.
Aside from oxygenating and regulating the nervous system, the nose is also a natural defense system. Its small hairs and mucous lining catch dust, allergens, and pathogens before they enter the lungs. It also humidifies the air before it reaches the lungs, making the respiratory system easier. Mouth breathing provides none of these protections and simply allows dry, unfiltered air to be introduced directly into the lungs, elevating the risk of irritation, inflammation, or infection. This added stress can even indirectly impact cardiovascular health in the long term.
The combined effect of nasal breathing is evident in its beneficial effect on cardiovascular performance. Not only does it regulate blood pressure and heart rate, but it protects the lungs and allows for more efficient oxygenation of the body. You're an athlete wanting to enhance performance; you're a stress manager looking to reduce pressure; you're a long-term care patient seeking general health. Nasal breathing is an easy adjustment with wide-ranging benefits.
In short, the way you breathe is more important than you realize. According to Dr. Jeremy, this simple action, when breathed through the nose, can make a huge difference in your overall health. From increased circulation to lowered anxiety, breathing through the nose is a powerful, natural mechanism for physical and emotional equilibrium. So, the next time you take a pause to breathe, have it pass through your nose, your body will appreciate it.
