Comparing Health Benefits of Nose Vs. Mouth Breathing

The article provides a comprehensive analysis of nose breathing vs. mouth breathing. It underscores the multifaceted benefits of nose breathing, including its natural filtration, humidification, and temperature-regulating properties. These attributes contribute to improved respiratory and cardiovascular health, as well as overall well-being. In contrast, mouth breathing is portrayed as having potential downsides, such as reduced filtration, humidification, and nitric oxide production, along with the risk of oral health and facial development issues.

Overall, the article serves as an informative resource for people seeking to understand the implications of their breathing habits on their health.

What Are the Advantages of Nose Breathing Vs. Mouth Breathing

Nose breathing and mouth breathing are two distinct methods of inhaling and exhaling air, ultimately delivering oxygen to the lungs, and they come with their own distinct effects for our health and well-being. However, nose breathing and mouth breathing have distinct characteristics and implications. Here’s a closer look at the differences between the two:

Nose Breathing

Your nose plays a crucial role in facilitating safe, efficient, and proper breathing. Its unique features enable it to perform several important functions:


The presence of nasal hair in the nasal passages structures trap airborne particles, dust, allergens, and pathogens, preventing them from entering the respiratory system

Humidify inhaled air:

The nasal passages warm and humidify the inhaled air by adding moisture. It brings the air you take in to body temperature.

Nitric Oxide Production:

The cells lining the nasal passages contain enzymes that produce nitric oxide. When you breathe in through your nose, the airflow comes into contact with these cells, leading to the release of nitric oxide gas into the nasal airway.

Cardiovascular Health:

Nitric oxide plays a vital role in maintaining healthy blood pressure levels. It helps to reduce resistance to blood flow, dilating blood vessels, which in turn can lead to lower blood pressure. This is crucial for overall cardiovascular health.

Mouth Breathing

Chronic mouth breathing, particularly during childhood and adolescence, can have lasting effects on facial and jaw anatomy.

Longer Face:

Chronic mouth breathing might contribute to facial changes that result in a longer, less harmonious appearance of the face.

Limited Humidification:

Mouth breathing doesn’t provide the same level of humidification, which can lead to dryness in the respiratory tract and discomfort.

Oral Health Issues:

Chronic mouth breathing can lead to dry mouth, increasing the risk of dental problems and bad breath.

While there are situations where mouth breathing is necessary:

  • Small Nostrils
  • Nasal Congestion
  • Enhanced Ventilation
  • A Deviated Septum

While breathing through the mouth in these situations can be beneficial and even necessary, it’s important to recognize the distinction between situational needs and chronic mouth breathing habits.

Because outside of these situational needs, mouth breathing can lead to health issues. Here are some of the associated issues:

  • Oral Health Issues
  • Allergic Reactions To Allergens
  • Snoring
  • Sleep-Disordered Breathing
  • Teeth Or Jaw Abnormalities
  • Inhaling Unfiltered Air
  • Dry Mouth (Xerostomia)

Is One Better for You Than the Other?

While nose breathing is generally preferred for its numerous health benefits and the specialized functions of the nasal passages, there are circumstances where mouth breathing becomes necessary or unavoidable.

Addressing chronic mouth breathing during sleep is crucial for preventing potential issues.


Many people tend to overlook their breathing patterns, and some may not even be aware of the potential impact that breathing through the mouth can have on their.
