Why Nose Breathing Is Important

Why Nose Breathing Is Important.

Worldwide research has proven that nose (nasal) breathing is the correct and most optimal way to breathe. Our bodies are designed for nose breathing based on the specific apparatus and the mechanisms by which we inhale and exhale, also there are numerous health benefits to be had from correct and consistent nose breathing.

Mouth Breathing

Unfortunately mouth breathing bypasses the important stages in the breathing process, which leads to many health problems such as snoring and sleep apnea.

With regards to dental health, breathing through the mouth can dry the oral cavity and lead to bad breath, gum disease and tooth decay.

Children who mouth breathe generally have a smaller chin, slower growth and produce poor performance at school due to fatigue and inattention. Causes of mouth breathing in children can range from things like enlarged tonsils and/or adenoids to allergies. The good news is that if your child is a regular mouth breather, pop in and see your local doctor who can examine them and offer appropriate solutions to help move from mouth to nose breathing.

Your nose is the only organ able to properly prepare the air you breathe, whereas mouth breathing leads to over breathing, chronic hyperventilation, elevates your blood pressure and heart rate and worsens allergies, asthma, rhinitis, etc. It also deprives your heart, brain and other organs of the optimal oxygen they require.

Breathing through your mouth tricks your brain into thinking that carbon dioxide is escaping the body too quickly. This in turn stimulates the production of mucous, as the body attempts to slow the breathing.

Mouth breathing at night can cause or worsen dry mouth due to the drying out of the mucous linings of the airway passages, especially in older people, which can lead to hoarseness, bad breath, and dental problems.

Cardiovascular Type Exercises

Nasal breathing is much more efficient than mouth breathing in terms of supplying oxygen to our bodies. Therefore, when performing cardiovascular type exercises, it would be preferable to inhale and exhale through the nose. However, with exercise you can become out of breath and it is obviously faster to exhale through the mouth than the nose: But this will reduce the amount of oxygen extracted from each exhalation.

Another very important role the nostrils and sinuses play is that they filter and warm the air that is inhaled into the lungs. This assists in keeping bacteria and particles out of your body. When exercising in very cold weather, breathing through the nose prevents the cold air going directly to your lungs, causing chest and throat pain.


10 Benefits of Breathing Through your Nose:

1 The air we breathe in through the nose is warmed and moistened, therefore it doesn’t irritate the sensitive airways.
2 The air inhaled through the nose helps filter out dust and other allergens.
3 Promotes good oral health, whereas mouth breathing dries out the air passages and gums, it increases the acidity in the mouth that can lead onto cavities and gum disease.
4 It regulates the volume of air breathed, thus maximizing the body’s oxygen needs.
5 Nasal breathing assists in the reduction of snoring and sleep apnoea.
6 Nasal breathing encourages good facial development and straighter teeth, due to the fact that with a closed mouth the tongue mostly resides in the roof of the mouth, which helps with the development of the jaw to accommodate all the teeth.
7 It lowers the heart and breath rate, compared to mouth breathing.
8 Increases brain wave coherence (associated with the calm and organized brain function), compared to mouth breathing.
9 Increases the production of nitric oxide that is important for increasing blood flow, expands blood vessels and protects the organs from damage.
10 Air that is exhaled through the nose reabsorbs moisture efficiently thus reducing dehydration.

Nose Breathing

Some people will constantly breathe through the mouth because they have chronic nasal congestion or perhaps an anatomical abnormality within the nose, such as a deviated septum. If you are having difficulties breathing through your nose consistently then please consult with your local doctor, in some cases they may refer you onto an ear, nose, and throat specialist.

To summarise:

Our bodies are designed for air to flow in and out via our nose. The air flowing in is filtered, warmed and moistened making it suitable for our airways and lungs and it’s also good for our oral health!
On the other hand, our mouth is designed for eating, drinking, and speaking, at all other times it should remain closed.
