Which way is better, breathing through the nose or the mouth? For better health

We may not think much about how we breathe on a daily basis, but breathing through the nose or mouth is not just a small difference, it's a habit that directly affects our health and quality of life.


The nose is not just an airway; it's an integrated system for purifying, humidifying, and preparing the air for the lungs. While mouth breathing may sometimes seem like a quick fix, in the long run it can carry unexpected risks, such as dry throat, snoring, and sleep disturbances.

Understanding the difference between the two methods is the first step toward improving your breathing and enjoying better health and deeper sleep.


Is it better to breathe through the nose or mouth: what does the body prefer?

Breathing is the simplest human function, but it's not really a mechanical process. Choosing between mouth or nose breathing can make a huge difference to your health.

  • The nose acts as the first line of defense, humidifying and warming the air before it reaches the lungs, and filtering it from dust and germs.


  • The mouth overrides these normal functions, which can lead to dry throat, recurrent respiratory infections, and sleep disturbances such as snoring.

For this reason, the body always prefers nose breathing as the natural way to maintain breathing balance and the quality of your health in the long term.

Why is nose breathing the best choice for your health?

If you're wondering which is better, breathing through your mouth or your nose? Nose breathing isn't just a natural habit; it's a mechanism designed by the body to protect you and support your overall health. When air passes through the nose, a series of vital processes occur that make breathing safer and more effective:

  • Air purification : The fine hairs inside the nose act as a natural filter that traps dust, bacteria, and pollutants before they reach the lungs.


  • Humidifies and warms the air : The nasal mucosa prepares the air to match the body's temperature and humidity, reducing airway irritation.


  • Increased oxygen levels : Breathing through the nose stimulates the production of nitric oxide.
  • (Nitric Oxide), a compound that helps dilate blood vessels and improve oxygen distribution in the body.


  • Boosting immunity : Thanks to these functions, the body becomes better able to resist infection and support the immune system naturally.


That's why nasal breathing is considered the best option for maintaining lung health, sleep quality, and even daily energy levels.


When should we resort to mouth breathing? Possible cases and risks

Although breathing through the nose is the natural and best option, there are situations that may prompt us to breathe through the mouth temporarily or permanently.


Common cases of mouth breathing:


  • When you have a blocked or stuffy nose due to a cold or allergies.


  • During intense exercise when the body needs a larger amount of oxygen quickly.


  • When there are structural problems in the nose, such as a deviated septum or enlarged adenoids.



Long-term harms of mouth breathing:

  • Dry mouth and throat , which increases the likelihood of tooth decay and gum infections.


  • Sleep disorders such as snoring and sleep apnea.


  • Poor quality of inhaled air because it does not go through the purification and humidification process provided by the nose.


  • General fatigue due to inefficient oxygen flow into the body.


Therefore , mouth breathing is considered a temporary solution in some cases, but continuing to do so may lead to health problems that require intervention and treatment.



How to get rid of mouth breathing while sleeping

Mouth breathing while sleeping may seem normal, but over time, it negatively impacts your health and the quality of your night's sleep. Fortunately, there are simple steps to address mouth breathing and help you return to normal nasal breathing while sleeping:

  • Treating nasal congestion : Treat nasal congestion and mouth breathing by using saline sprays or consulting a doctor to treat allergies or a deviated septum.


  • Keep the room humid : Dry air makes nasal breathing more difficult, so it's best to use a humidifier.


  • Sleeping on your side: Instead of sleeping on your back, this helps reduce snoring and mouth breathing.


  • Commitment to breathing exercises : Practice deep breathing exercises through the nose during the day to train the body to adopt this habit.


  • Use of aids : such as the Breth nasal strip, which opens the airway and prevents the mouth from remaining open during sleep.


By following these steps, anyone can improve their nighttime breathing and enjoy deeper, more restful sleep.
