The structure of one's face and oral cavity can influence breathing patterns. Medical conditions such as sinusitis or respiratory inflammation often alter the airway structure, causing nasal congestion and leading to a habit of mouth breathing instead of normal nasal breathing.

Individuals who breathe through their mouth from a young age, whether due to habit or underlying medical conditions, can experience effects on their facial and jaw anatomy. They commonly exhibit a longer facial length, measured from the forehead to the point between the eyebrows. Frequent mouth breathers may also have a protruding upper jaw, a prominent forehead, and a long, narrow face. Mouth breathing also affects tongue position, causing it to rest lower to allow more air entry.

Both mouth and nasal breathing deliver oxygen to the lungs, but nasal breathing is preferred. It promotes proper alignment of the upper and lower jaws, helping maintain average facial height and a balanced mandibular plane angle.

Mouth breathing negatively impacts oral health, often leading to malocclusion, an increased risk of jaw misalignment, and crooked teeth. This breathing habit dries the mouth, creating conditions favorable for the development of gingivitis, periodontitis, and cavities. Additionally, dry mouth contributes to chapped lips, bad breath, oral pain, and drooling during sleep.

In contrast, nasal breathing offers numerous benefits for the respiratory system. Nasal hairs and mucous cilia function to filter out dust, allergens, and airborne pollutants. Moreover, the turbinates warm and humidify inhaled air before it reaches the lungs, protecting the throat and lower airways. The nasal cavity also helps regulate air temperature, aiding the body in maintaining a stable core temperature.

Several techniques can help you retrain proper breathing:

Alternate nostril breathing: This yoga practice, involving alternating breaths through each nostril, is often recommended to improve respiration. It enhances lung, heart, and cognitive health, reduces stress, and thereby helps modify breathing patterns.

Diaphragmatic breathing (belly breathing): This technique focuses on utilizing the diaphragm, the primary respiratory muscle located beneath the lungs. Like other breathing exercises, it improves lung function.

Breath of fire: This breathing technique involves normal inhalation followed by rapid, forceful exhalations. It requires breathing entirely through the nose, without opening the mouth. This method can enhance lung function, reduce anxiety, and improve memory and other cognitive functions.
