Mouth vs. Nose Breathing: 6 Science-Backed Reasons to Breathe Correctly

Benefit 1: A beautiful face

Being a mouth breather, especially while younger, can lead to an elongated and narrow facial shape that does not have room for teeth or tongue. When you breathe through your nose, your tongue naturally fills your palate space and exerts an upward and outward pressure. It promotes forward growth of the jawbones which will give your face a fuller look and a sharper jawline.

Benefit 2: The marvels of nasal cilia

Inside your nose lies a remarkable defense mechanism—tiny hairs called cilia. These unsung heroes filter, warm, and humidify the air you breathe, shielding you from a staggering 20 billion foreign particles daily.

Benefit 3: Debunking exercise mythology

Contrary to common belief, research dispels the notion that mouth breathing is necessary for optimal air intake during exercise. Studies reveal that nose breathing, despite its resistance, leads to 10–20% better oxygenation, debunking the need for open-mouthed exertion.

Benefit 4: Efficiency unleashed

Nose breathing emerges as the efficiency champion, being 22% more effective than its mouth counterpart. This revelation translates to easier breathing and less fatigue for the respiratory muscles, offering a game-changing perspective on how we approach physical exertion.

Benefit 5: Clear airways, clear victory

Breathing through the nose keeps airways clear, a stark contrast to the congestion induced by mouth breathing. Addressing the age-old question of how to breathe with a stuffy nose, the surprising solution lies in embarking and acclimating to nose breathing.

Benefit 6: The art of nasal exhalation

Unraveling a hidden aspect of respiration, we discover that nasal exhalation creates a backflow of air into the lungs during nose breathing. This prolonged interaction between air and lungs enhances oxygen extraction, promoting a more efficient respiratory process.
