For the majority, breathing is an unconscious process, overlooked in daily life. However, the method of respiration, whether through the nose or mouth, can significantly influence an individual's health. While both methods help bring oxygen into the body, one is much better for our respiratory system than the other. So, here is everything we need to know about nose breathing vs mouth breathing and which one is healthier and why.
Oxygen intake
When we breathe through our nose, the air passes through tiny nasal passages that filter, humidify, and warm it before it reaches your lungs. This makes oxygen absorption more efficient. On the other hand, mouth breathing delivers dry and unfiltered air straight to your lungs, making it less effective at oxygenating our body. Over time, this can lead to lower energy levels and fatigue.
Air filtration
Our nose has tiny hair-like structures called cilia and a mucus lining that traps dust, bacteria, and other harmful particles. This keeps our lungs safe from pollutants and infections. Mouth breathing, however, allows all these unwanted particles to enter directly, increasing the risk of respiratory infections, allergies, and even lung irritation.
Lung health
Since nose breathing delivers warm and moist air to the lungs, it prevents dryness and irritation in the airways. In contrast, mouth breathing can dry out the throat and lungs, making them more susceptible to inflammation, congestion, and conditions like asthma. If you often wake up with a dry mouth or sore throat, it could be a sign that you are breathing through your mouth while sleeping.
Carbon dioxide balance
Our body needs the right balance of oxygen and carbon dioxide to function properly. Nose breathing slows down the breathing process, allowing your body to maintain healthy levels of carbon dioxide. This helps keep blood vessels relaxed and supports overall lung function. Mouth breathing, however, often leads to shallow and rapid breaths, which can disrupt this balance and cause issues like dizziness, anxiety, and even high blood pressure.
Impact on sleep and snoring
If you or someone you know snores loudly, chances are they breathe through their mouth while sleeping. Mouth breathing is linked to snoring, sleep apnea, and poor sleep quality. On the other hand, nose breathing promotes deeper sleep, reduces snoring, and helps the body recover better overnight.
