Advantages Of Breathing Through Your Nose
Breathing through your nose comes with a few key advantages. The human nose produces nitric oxide, which helps your lungs to absorb oxygen more efficiently. Nitric oxide is also important in the transport of oxygen throughout the body, including to the heart. When it is produced naturally, it helps the blood vessels to dilate and relaxes the smooth muscles in your heart for improved absorption of oxygen. Nitric oxide also has antibacterial, antifungal, antiparasitic, and antiviral properties, which means it can help your immune system function more efficiently.In addition to producing nitric oxide, the act of breathing through your nose can help filter out tiny particles in the air you breathe. When cold air passes through the nostrils, its warmed slightly before it reaches the lungs. Your nose can also add moisture to dry air, reducing irritation to the lungs and bronchial tubes. As you breathe through your nose, the action naturally adds resistance to the stream of air, which boosts the elasticity of the lungs and increases the oxygen uptake.
What Are Mouth Breathing Symptoms
Many mouth breathing symptoms affect children and adults the same way. Here are some examples:
- Dry mouth: Breathing through your mouth as you sleep dries salvia that keeps your mouth moist.
- Bad breath: Mouth breathing affects saliva flow that usually keeps your mouth clean.
- Drool on pillows: Saliva that usually collects in your mouth seeps out from your open mouth.
- Malocclusion:Malocclusion happens when your upper and lower teeth dont align.
Children who mouth breath have different and more serious symptoms:
- Mouth breathing face:Mouth breathing can affect childrens facial development, causing whats called mouth breathing face. People who have mouth breathing face often have narrowed faces with receding chins or jaws.
- Behavior problems:Studies show some children with mouth breathing develop behavioral problems that are similar to problems found with children who have attention deficit hyperactivity disorder .
The Nose Filters Heats And Humidifies Air
As air is inhaled through the nasal membranes dust and dirt are filtered and removed. The air is also heated up and humidified. Air that is hot, clean and humidified is quickly absorbed by the lungs. Nasal breathing also oxygenates the nasal membranes and sinuses. Oxygen kills anaerobic bacteria that cause sinus and nose infections. Oxygen promotes growth of healthy bacteria in the nose and sinuses. In people who nose breathe their immune system works better and they get less bacterial and viral infections.

Why Is It Better To Breathe Through The Nose
You might think that air is air, and as long as were getting enough of it into our bodies, it doesnt make a difference how we breathe it. But thats not entirely true the mechanics of breathing mean that air that came in through the nose is different from air from the mouth.
The reason why this is so important is because when you breathe through the nose, you are forcing air through all of these very intricate structures. And as that air is forced through these structures, it’s heated up, its humidified, it’s pressurised, and it’s filtered, Nestor says. So, that air, when it gets to your lungs, can be so much more easily uploaded into your bloodstream.
We can extract about 20 per cent more oxygen breathing through our noses than we can equivalent breaths through our mouths. Thats no small difference, especially when youre exercising. A 1996 study showed that breathing exclusively through the nose during exercise not only lowers your breathing, but also significantly increases your endurance. And on top of that, you might even feel more comfortable doing it: participants felt like they were exerting themselves less.
The noses filtration system also plays an important role in your immune system. First, air passes the nasal hairs in your nostrils, which capture pollen and other allergens. A study published in 2011 showed that hay fever sufferers with a greater density of nasal hairs were less likely to develop asthma.
Mouth Breathing: How To Spot It And Fix It
Posted on April 16, 2021 by Site Admin –News & Updates
Breathing is one of the most vital functions of the human body, and provides our bodies with the oxygen we need to survive. But despite this, most of us dont think about how we breathe.
There are two air passageways to your lungsyour mouth, and your noseand healthy people use both to breathe. During strenuous exercise, you may breathe through your mouth to help oxygen get to your muscles faster, but consistent mouth breathing can lead to various health issues.
So what is mouth breathing, what are some of the symptoms, and how is it diagnosed and treated?

Nose Breathing Helps Fight Infections
When you breathe in through your nose, the air is warmed, moistened, conditioned, and mixed with nitric oxide- which does two important functions- it kills deadly bacteria and works as a vasodilator on the airways, arteries, and capillaries.
Our body has a gene T2R38, that stimulates the noses receptors when you breathe through your nose, which reacts with the chemicals that bacteria in the air use to communicate. It stimulates nitric oxide that kills the bacteria, so you breathe in relatively less infectious air.
Mouth Breathing Vs Nose Breathing
Experts agree that breathing through your nose has many more benefits than mouth breathing. Our noses process air differently than our mouths do. These differences are our bodyâs way of keeping us safe and healthy. When you breathe in through your nose, it:
Controls temperature. Your lungs prefer air thatâs not too cold and not too hot. Unless you have a block, like a deviated septum or chronic rhinitis, your nose will warm or cool the air that goes into your lungs. This will help the air reach an ideal temperature for your body. Mouth breathing doesnât do this.
Filters toxins. The small, hair-like structures called cilia in your nose filter out toxins and debris when you breathe. They help send them to your throat instead of your lungs. Mouth breathing directs everything you breathe into your lungs.
Humidifies. Your nasal passages humidify the air you inhale. Your mouth doesnât typically do this, which is why some mouth breathers wake up with dry mouth or a sore throat.
Senses smell. Your nose can smell harmful substances in the air or your food. Your mouth canât find these toxins as effectively.
The only time itâs absolutely necessary to breathe through your mouth is when youâre doing intense exercise or if your nose is blocked from congestion, a cold, or allergies. Temporary mouth breathing can help you get air to your lungs quicker in these situations.

Breathe Out Of The Nose
If you don’t breathe out of the nose when swimming, you’re bound to end up with water in your face and sand in your eye. And if your technique is rusty, it may be even trickier to breathe out of the nose! To overcome this issue, here are some tips. First, exhale slowly through your nose. You’ll need to breathe out slowly and deeply to avoid getting water in your nose.The next tip is to exhale deeply. Exhaling through the nose is easier than from the mouth, but it’s more natural. To learn how to breathe out of the nose while swimming, start with the front crawl and gradually introduce it into your stroke. Make sure you breathe every three strokes until your head reaches its highest position. Then, repeat the process for the remainder of your hand movements. There are breathing suggestions for newcomers and they should understand the importance of breathing and its methods..
Nose Breathing Is Better For Your Health And Plays An Important Role In Immune System Function
Lundberg J, Weitzberg E. Nasal nitric oxide in man. Thorax.1999 :947-952
Among the various biological properties of nitric oxide are its effects on the growth of various pathogens including bacteria, fungi, and viruses.
What does it mean?
Nitric oxide offers a natural first line of immune system defense against airborne pathogens such as viruses.

Nose Breathing Increases Arterial Oxygen Tension
Lundberg JO. Nitric oxide and the paranasal sinuses. Anat Rec .2008 Nov ):1479-84
Nitric oxide is released in the nasal airways in humans. During inspiration through the nose this NO will follow the airstream to the lower airways and the lungs. Nasally derived NO has been shown to increase arterial oxygen tension and reduce pulmonary vascular resistance, thereby acting as an airborne messenger.
What does it mean?
When you breathe through your nose, you inhale nitric oxide deep into your lungs. Nitric oxide helps more oxygen get into your blood.
Is Mouth Breathing Reversible
“People think they grew to this face because of genetics â- it’s not, it’s because they’re mouth-breathers.” It’s reversible in children if it’s caught early — an orthodontist might use a device to expand the jaw, which will widen the mouth and open the sinuses, helping the child breathe through the nose again.

Mouth Breathing Causes Constriction Of Blood Vessels
You can’t kiss someone and breathe through your mouth.
You may think that by opening your mouth to breathe you are taking in more air, but in reality, you are just slowing down the breathing. When mouth breathing, the brain thinks carbon dioxide is being lost too quickly and sensing this, it stimulates the goblet cells to produce mucus, slow the breathing and cause constriction of blood vessels. The nostrils and sinuses filter and warm the air going into the lungs. An average mouth breather bypasses this. The sinuses produce nitric oxide which is a pollutant- but in small doses, it is harmful to bacteria.
Nitric oxide is one of the very important chemical parts of sexual arousal. It vaso-dilates and plays a part in maintaining the erection.
Nasal Breathing Takes Practice
You can breathe far more air into your lungs through your mouth than you can breathe through your nose. You can exercise intensely when you breathe just through your nose, but you will need to practice :6425-6430). How intensely you can exercise depends on how fast oxygen can pass from red blood cells into muscle cells. The cells lining your nose and sinuses release large amounts of a gas called nitric oxide while the cells lining your mouth and throat do not . Breathing through your nose releases far larger amounts of nitric oxide, which specifically widens the very small blood vessels next to muscles to bring the red blood cells closer to muscle cells, to increase markedly the rate that oxygen passes from red blood cells to muscle cells.
One study showed that with training, you can get enough air while breathing through your nose to exercise at up to 85 percent of your maximum capacity :22). Ten recreational runners practiced nasal breathing during exercise for six months and when they breathed through their noses while exercising at up to 85 percent of their maximal capacity, they had the same: time to exhaustion, maximal capacity to take in and use oxygen , and peak lactate levels. .Nasal breathing brought in the same maximal amount of oxygen as mouth breathing, but nasal breathing markedly reduced: respiratory rate , and ratio of oxygen intake to carbon dioxide output.

Mouth Breathing Vs Nasal Breathing
Proper breathing is vitally important for our health. This might sound strange coming from a Dentist but Dentists are in a unique position to help screen their patients for breathing disorders. Dentists may be the first healthcare professionals to have contact with children who might be mouth breathers. I feel that it is very important for us to screen children for mouth breathing. So, why is it important for us to breathe through our noses?
Proper breathing through the nose helps us breathe better. Firstly breathing in through our nose helps get rid most of the allergens and microbes in the air. Secondly, the air gets humidified naturally and lastly gets mixed with nitric oxide from the sinus area. This mixing with nitric oxide is thought to increase the ability to absorb oxygen.
When we breathe out through our nostrils, it actually takes us longer to exhale. This is important because absorption of oxygen actually happens during exhalation. So the increase in time that it takes for us to breathe out through our noses helps us absorb oxygen better. It is thought that you actually absorb Oxygen around 15% better when you exhale through your nose when compared to mouth breathing.
So, while this is all good but what is the big deal if you are a mouth breather. Firstly we have to
It Helps During Your Workouts
The lungs are a primary source of our energy level. They extract oxygen from the air we breathe primarily on the exhale. When you exhale through small nostrils compared to your mouth, a back-pressure is created, and exhaled air is restricted and slowed down, which is precisely the time the lungs use to absorb more oxygen.
It slows the air escape, so the lungs have more time to extract oxygen from them. The blood will maintain a balanced pH when there is proper oxygen-carbon dioxide exchange. Our oxygen uptake happens mostly during the restricted exhale through the nose.
Oxygen absorption is decreased if carbon dioxide is lost too quickly, as in mouth breathing. If you want better performance during your exercise, you have to stop over-breathing or hyperventilation- a.k.a mouth breathing. Nose breathing imposes approximately 50 percent more resistance to the air stream in normal individuals than does mouth breathing, resulting in 10-20 percent more O2 uptake.
“During exercise, nasal breathing causes a reduction in FEO2, indicating that on expiration the percentage of oxygen extracted from the air by the lungs is increased and an increase in FECO2, indicating an increase in the percentage of expired air that is carbon dioxide”. :51-5. PMID: 8599744)

How Nitric Oxide Kills Viruses
In an in vitro study done in 2004 during the last SARS outbreak, experimental compounds that release NO increased the survival rate of nucleus-containing mammalian cells infected with SARS-CoV. This suggested that NO had a direct antiviral effect. In this study, NO significantly inhibited the replication cycle of SARS-CoV by blocking production of viral proteins and its genetic material, RNA.
In a small clinical study in 2004, inhaled NOwas effective against SARS-CoV in severely ill patients with pneumonia.
The SARS CoV, which caused the 2003/2004 outbreak, shares most of its genome with SARS CoV-2, the virus responsible for COVID-19. This suggests that inhaled NO therapy may be effective for treating patients with COVID-19. Indeed, several clinical trials of inhaled NO in patients with moderate to severe COVID-19, who require ventilators, are currently ongoing in several institutions. The hope is that inhaled NO will prove to be an effective therapy and lessen the need for ventilators and beds in the ICU.
The sinuses in the nasal cavity, but not the mouth, continuously produce NO. The NO produced in the nasal cavity is chemically identical to the NO that is used clinically by inhalation. So by inhaling through the nose, you are delivering NO directly into your lungs, where it increases both airflow and blood flow and keeps microorganisms and virus particles in check.

Maintain Normal Blood Pressure
As a vasodilator, nitric oxide helps widen the blood vessels that increases the oxygen in the blood. Consequently, this process helps maintain lower blood pressure. According to Dr. Hernan Chang in his book Nitric Oxide: The Mighty Molecule, nitric oxide serves a crucial role in heart health, endocrine system, and immune systems and is extremely significant throughout the human body.

Nose Breathing Improves Pulmonary Function
Airway physiology. Tidsskr Nor Laegeforen. 1999 Nov 10 119
Nitric oxide has important functions in a variety of physiological and pathophysiological processes in the body, including vasoregulation, haemostasis, neurotransmission, immunity and respiration. The discovery of surprisingly high concentrations of NO in the nasal airway and paranasal sinuses has important implications for the understanding of airway physiology. The high NO levels in the nasal and paranasal airways contribute to the first line defence against microorganisms. Furthermore, autoinhalation of nasal NO may improve pulmonary function and other remote physiological processes.

The nitric oxide you inhale during nose breathing improves the function of your lungs, immune system, blood vessels and breathing.
Untying The Tongue Assists In Nose Breathing
People who do not have tongue and lip ties and who have healthy tongue function will not be mouth breathers. Reread that again. If you have proper tongue function, you will not be a mouth breather. Ultimately tongue and lip ties cause all upper airway problems during infant and child growth and development. There is a cause and effect relationship between tongue tie, poor tongue function and mouth breathing.

Physical Effects Of Nose Breathing Vs Mouth Breathing
One 2017 study examined the differences between nose breathing and mouth breathing during exercise. The researchers found that nose breathing during anaerobic exercise decreased the chance of hyperventilating.
They also noted that breathing through the nose produces nitric oxide. This may improve performance during exercise, although future studies are necessary to investigate this further.
Research also indicates that nose breathing may affect a personâs ability to think. Another study found enhancements in brain activity when participants were nose breathing. There was also a strengthening of connections between different brain regions during this breathing type.
The researchers did not observe these cognitive benefits during mouth breathing. They concluded that this breathing method may negatively affect a personâs ability to think.
