Nasal Breathing vs. Mouth Breathing: Which Is Better for Your Airway Health?

Updated: Jan 26

Nasal breathing and mouth breathing play essential roles in our everyday lives. However, they serve different functions, and their impact on airway health is distinct. Continue reading to compare nasal and mouth breathing and evaluate their benefits and drawbacks.

What Is Nasal Breathing?

Nasal breathing refers to inhaling and exhaling through the nose, which is critical for various reasons.

● Filtration: The nose has tiny hair-like structures called cilia that trap dust and other particles, acting as a natural air filter.

● Humidification: The nose moisturizes the air we breathe, preventing the dryness of our respiratory tract.

● Air Warming: The nose also helps warm the air to body temperature, making it easier for the lungs to use.

What Is Mouth Breathing?

Mouth breathing is inhaling and exhaling through the mouth instead of the nose. While it can be helpful during intense physical activity, consistent mouth breathing can have several negative health impacts.

● Dry Mouth: Mouth breathing can lead to dry mouth, causing bad breath and potentially leading to gum diseases.

● Throat Irritation: The mouth doesn’t humidify air like the nose, which can result in throat dryness and irritation.

● Poor Sleep Quality: Chronic mouth breathing can result in lower sleep quality, leading to snoring and conditions like sleep apnea.

Nasal Breathing vs. Mouth Breathing

Given the benefits and drawbacks, nasal breathing is generally better for airway health than mouth breathing. In addition to providing filtration, humidification, and air warming, it promotes better oral health and sleep quality.

However, it’s crucial to mention that in certain circumstances, mouth breathing is necessary and beneficial, like when the body requires more oxygen. In such cases, the body naturally shifts to mouth breathing to meet the increased oxygen demands. But for most of the day, especially during sleep, nasal breathing is preferred due to its benefits to airway health. If mouth breathing becomes habitual, it may be necessary to consult a healthcare provider because it can signal underlying health issues like nasal obstructions or sleep apnea.
