Mouth Breathing Treatment: Stop Mouth Breathing with 9 Easy Everyday Tips

Breathing is one of the most important aspects of life – in fact, without breathing, we cannot live. This is a commonly known fact.

Breathing is vital for allowing the body to receive oxygen, which all cells depend on to survive. Additionally, breathing also allows the body to get rid of waste products, including carbon dioxide, that is collected in the lungs.

You never concentrate on breathing, so we do not always consider how we breathe. Essentially, we can breathe air through either the nose or the mouth, both leading the air toward the lungs.

Normally, a person would use both their mouth and their nose to breathe in and out. The nose, however, is the main pathway that we use for breathing.

At times, however, when sinus or allergies strike, as well as the common cold, the nose may become congested and blocked – this makes breathing through the mouth essential. When the nose opens up again, we return to breathing through the nose.

In some people, however, breathing occurs primarily through the mouth. While this may not seem harmful at first, there are complications in both children and adults that may develop with mouth breathing.

In this post, we’ll explore how you can recognize the symptoms of mouth breathing, look at why it is vital to utilize your nose for breathing and consider some easy steps that will help you train your body to use your nose instead of your mouth for breathing.

How to You're a Mouth Breather

The first step to addressing mouth breathing is recognizing the symptoms. Since breathing becomes such an automated activity of the body, you often do not recognize the fact that we may be breathing through the wrong airway.

Mouth breathing is relatively common at night, especially, and can produce a number of symptoms in both children and adults.

In adults, symptoms of mouth breathing may include snoring at night, frequently experiencing dry mouth symptoms, halitosis, hoarseness of the voice, and waking up in an irritable mood.

You may also start to develop dark circles underneath your eyes and experience chronic fatigue. Some people also experience brain fog when they breathe through their mouth.

Children may experience irritability, enlarged tonsils, dry or cracked lips, daytime sleepiness and they may find it difficult to concentrate while at school.

Mouth breathing in children may also cause the child to experience a reduced growth rate and even cause them to cry frequently at night.

What causes mouth breathing?

blocked nasal

In the majority of cases where a person continuously breathes through their mouth instead of their nose, an obstruction in their nose is to blame.

When the body is unable to obtain its required oxygen supply through the nose, then the body will automatically resort to the mouth for getting the oxygen it needs to survive.

A blocked nasal airway is often caused by a sinus infection, a cold or by allergies, but other problems can also cause the nasal airway to become blocked. Such issues may include enlarged tonsils or adenoids, a deviated septum, and the growth of polyps in the nose. 

Additionally, the shape of a person's nose or their jaw may also have an impact on their risk of experiencing nasal congestion.

Individuals with obstructive sleep apnea are also prone to breathing through their mouth instead of their nose, especially during sleep.

It should be noted that after the nasal congestion has been resolved, some people may continue to breathe through their mouth instead of their nose as mouth breathing has become a habit for them.

Apart from nasal congestions, anxiety, stress and similar symptoms can also make a person prone to breathing through their mouth instead of relying on their nose for breathing.

Why is it important that you breathe through your nose?

It is important that individuals who frequently find themselves breathing through their mouth to realize why it is essential for them to adopt habits of breathing through their nose.

The nose is the primary airway that helps the lungs receive oxygen for many important reasons.

Firstly, nitric oxide is produced inside of the nose. Nitric oxide is an essential gassy substance that is carried to the lungs with the air that is breathed in – the nitric oxide helps to improve the absorption of oxygen by the lungs, leading to more oxygen being distributed throughout the body.

In addition to assisting with the absorption, the nitric oxide is also an important substance for the vasodilation of blood vessels – this helps oxygen-rich blood to be transported to all parts of the body more easily.

 In addition to providing an improvement in the absorption of oxygen in the body, the nitric oxide produced in the nose also contains agents that make the substance antibacterial, antiparasitic, antiviral and antifungal. 


This means nitric oxide can destroy pathogenic materials and help the immune system fight against bacteria, parasites, viral infections and fungal infections.

4. Adopt a good sleeping position

Your sleeping position also plays a part in allowing you to experience a relief of nasal congestion and ensuring you can easily breath through your nose while you are asleep. Sleeping on your back is a good way to prevent continuously breathing through your mouth as this position, when elevated at the top, can help to relieve nasal congestion.

5. Exercise​​​​

Physical exercise is beneficial for the entire body and contributes to a healthier immune system, as well as many other advantages. A study by James N. Baraniuk, MD and others indicated that aerobic exercise can help to provide a relief in nasal congestion within as little as half a minute.

8. Using nasal saline spray

The use of a saline nasal spray can also bring about relief of nasal congestion and even be helpful in the treatment of sinus infections. Additionally, a nasal saline spray will help to reduce inflammation that may be present in the mucous membranes and provide adequate levels of moisture to nasal passages that have become dry.

9. Using mouth guards

Mouthguards for snoring have been designed to help keep your mouth closed while you are sleeping. In turn, this avoids mouth breathing and will force your body to rely on your nasal airway to obtain oxygen instead.

You might also want to try using Continuous Positive Airway Pressure (CPAP) Machines. They are a common treatment for obstructive sleep apnea. A CPAP machine uses a hose and mask or nose piece to deliver constant and steady air pressure through the nose. By doing this they also offer relief for snoring caused by mouth breathing.
