The Dangers and Consequences of Mouth Breathing: Tips to Restore Nasal Breathing

**The Importance of Nasal Breathing for Health**

Respiratory health plays a vital role in overall well-being, and yet many individuals unknowingly engage in improper breathing habits that can negatively impact their health. The Taiwan Rhinological Medical Association recently organized an educational event called “Free Nasal Inhalation Clinic Tour Day” to raise awareness about the significance of correct breathing techniques. During this event, doctors from the Department of Otolaryngology at the National Taiwan University Hospital provided free consultations to the public, highlighting the importance of nasal breathing.

Breathing through the mouth is only meant to be a temporary substitute for nasal breathing and should not be considered a normal respiratory channel. Various factors can contribute to foul breath, including congenital or acquired breathing issues. Congenital factors may involve a curved septum or adenoid hypertrophy, while acquired causes commonly include hypertrophy of the inferior turbinate, which affects normal nasal breathing.

The nose and mouth serve different functions, and their impact on the body differs significantly. Nasal breathing allows the micro-vessels and mucus in the nasal mucosa to effectively filter dust, bacteria, and viruses from the air. The mucus layer also adds moisture and warmth to the inhaled air, reducing potential lung damage. Conversely, mouth breathing can cause dryness in the throat and lacks the respiratory mucous membrane’s ability to filter and adjust the air, resulting in the direct inhalation of pollutants into the lungs, thus negatively impacting overall health.

Long-term mouth breathing can lead to several conditions. First, it can contribute to crooked teeth, as the tongue is unable to maintain proper positioning against the roof of the mouth due to the lack of nasal breathing. This imbalance in mouth muscles can result in various dental issues and malocclusion. Second, mouth breathing increases the risk of respiratory infections since it does not filter harmful substances like nasal breathing does. This puts individuals, especially young children prone to tonsil hyperplasia, at a higher risk of developing respiratory tract infections. Lastly, mouth breathing reduces breathing efficiency. The nose’s filtering, warming, moisturizing, and antibacterial functions diminish when mouth breathing is practiced, leading to chronic hypoxia in the body, causing symptoms of chronic fatigue.

If individuals have become habituated to mouth breathing, it is crucial to seek treatment. Mouth breathing can adversely affect sleep, overall health, and mood. It can lead to sleep apnea, snoring, oxygen deprivation, and interruptions in the sleep cycle, resulting in reduced sleep quality. Continual mouth breathing also increases vulnerability to pathogens, as the air bypasses the natural filtration process of the nasal cavity. Various surgical and medical interventions are available to address nasal congestion and other related issues. By seeking professional help, individuals can successfully restore nasal breathing and maintain a healthy balance in their bodies.

For those looking to transition back to nasal breathing, experts recommend practicing four essential techniques:

1. Constantly remind oneself to breathe through the nose.
2. Inhale with lips tightly closed and the tongue resting against the roof of the mouth.
3. Avoid forced breathing and stabilize breathing rhythm.
4. If experiencing nasal congestion, apply a warm towel to the nostrils temporarily to relieve congestion.

By regularly performing these exercises and maintaining a comfortable pace and intensity, individuals can gradually develop the habit of nasal breathing, leading to improved overall health. It is important to consult with an otolaryngologist if experiencing chronic nasal congestion to receive a professional assessment and prevent further health issues associated with mouth breathing.

Health and Medical Network: “The Impact of Nasal Breathing on Respiratory Health

[Rhwydwaith Meddygol Iechyd / Gohebydd Zheng Yifen]The nose is the correct respiratory organ, but many people breathe through the digestive organ – the mouth. Ye Dehui, former chairman of the Taiwan Society of Rhinology and the Department of Otolaryngology of the National Taiwan University Hospital, reminded that when the public finds that the resistance of mouth breathing is small and easy, they will naturally get used to breathing through the mouth, reducing stimulation leading to slower development, and the shape of the face will change accordingly, causing abnormalities in the upper and lower jaws, which will easily lead to malocclusion. People who are used to mouth breathing can practice 4 tips to regain “nasal breathing”.

Respiratory information is very different Use the wrong method to breathe pollution directly into the body

Correct breathing is often neglected, and many people breathe in the wrong way without realizing it, which affects their health. On the 20th, the Taiwan Rhinological Medical Association held a health education activity called “Free Nasal Inhalation Clinic Tour Day”. Doctors Su Yuyan and Dr. Zhao Junhao from the Department of Otolaryngology of National Taiwan University Hospital provided free consultations to the public on the spot.

Mouth breathing is only a temporary replacement for nasal breathing, not a normal breathing channel, and causes of foul breathing include congenital or acquired breathing:

Congenital: Common eg curvature of the septum or adenoid hypertrophy.Acquired: The common one is hypertrophy of the inferior turbinate, causing the nose not to breathe normally.

Although breathing can be done through the mouth or through the nose, the functions of the nose and mouth are different, and the effects on the body are also very different.

nasal breathing

When air enters through the nose, the micro-vessels and mucus of the nasal mucosa can effectively filter dust, bacteria and viruses in the air, The mucus layer can moisten and warm the inhaled air and reduce air damage inhaled into the lungs.

mouth breathing

It is easy to make the throat dry, and there is no respiratory mucous membrane in the mouth to filter and adjust the air, so these pollutants in the air can be inhaled directly into the lungs, seriously affecting on the health of the body.

Breathing through the mouth for a long time can lead to 3 conditions

The rapid industrial development in recent years has led to increasingly serious air pollution, and the climate of the island of Taiwan makes the environment hot and humid with large temperature differences. According to the analysis of health insurance declaration data, the number of Chinese people seeking medical treatment due to allergic diseases in 2018 was about 3.55 million, and the doctor seeing rate was 15,038 per 100,000 population 54.0%), showing that allergies nasal is quite common in Taiwan.

Non-allergic rhinitis is also a major problem, and rhinitis caused by non-allergic causes is more likely to occur in adults over the age of 20. Swollen inferior turbinate mucosa is often found in patients with chronic rhinitis Many patients have a curved nasal septum at the same time, causing many patients to feel that their noses are blocked and want to breathe through their mouths; If you use mouth breathing for a long time, these problems can lead to the following three situations:

1 crooked teeth

When breathing through the mouth, the tongue must be flat against the bottom of the mouth. Over time, the strength to lift the tongue is not sufficient, and the muscles in the mouth are unbalanced. In the long term, problems such as crooked teeth, buckets, malignant, and malocclusion lead to causing diseases of other organs.

2 Increased risk of respiratory infections

Mouth breathing cannot filter harmful substances in the air as effectively as nose breathing, so it is more likely to cause respiratory tract infections, especially in young children who are prone to tonsil hyperplasia.

3 Reduced breathing efficiency

The nose has filtering, warming, moisturizing, and antibacterial functions. If you switch to mouth breathing, you will lose the protective function of the nose. And because the oxygen content in the blood is reduced, it will cause chronic hypoxia in the body in the long term, leading to symptoms of chronic fatigue.

How is mouth breathing treated?

Zhang Zhihui, an otolaryngologist at Zhenxing Hospital, shared that if you get used to mouth breathing for a long time, it will affect your sleep, health and mood. It is also prone to apnea, snoring, lack of oxygen, sleep apnea , etc., which interrupt the sleep cycle and reduce the quality of sleep; Sensitive patients who use their mouth to breathe for a long time, because the air does not pass through the nasal cavity and loses the filtering function, it is easier for pathogens to enter the body and affect on their health.

Nasal allergies are quite common in Taiwan With the development of medical technology, in addition to drug treatment, there are also various surgical methods for treatment. Xu Yingshuo, head and neck otolaryngology surgeon at Xinguang Hospital, said there are three main reasons for the pain caused by nasal congestion surgery: the wound is too large, the field of vision is limited, and the anesthesia does not get administered properly, and the nasal congestion after surgery stops bleeding, which makes it impossible to breathe through the nose However, there are many advanced surgical procedures. The method and r new medical materials are optional. After the operation, the bleeding can be stopped quickly, so that the patient can breathe through the nose immediately without pain, and there is no need to go through the process of removing the nasal stuffing Observe after the operation, and the next day will be fine Go back to your daily routine and save a lot of hospital time.
