and the mouth for taking in food!

Breathing is a fundamental aspect of life, but the way we do it can have a significant impact on our health and well-being. A large proportion of the population breathes more through their mouths, both day and night. Current scientific findings show us why we should focus on nasal breathing.

  1. Filtration and humidification:
  • The nose acts as a natural filtering system, trapping particles and bacteria from the air. In addition, it humidifies the air to ensure that the delicate airways remain moist. This natural filtration and humidification process helps prevent respiratory infections and irritation.
  1. Production of nitric oxide:
  • The sinuses located in the nose produce nitric oxide - a powerful vasodilator. Meaning nitric oxide helps dilate blood vessels, improves oxygen uptake in the lungs, and promotes overall cardiovascular health. Mouth breathing bypasses this essential process and foregoes the benefits of nitric oxide.
  1. Regulating the air flow:
  • Nasal breathing allows for a regulated flow of air. The nostrils have small, hair-like structures that create resistance, ensuring a controlled and even flow of air enters the lungs. This resistance stimulates the diaphragm and activates the lower lungs, promoting a more efficient exchange of oxygen and carbon dioxide.
  1. Improved oxygen supply:
  • Nasal breathing facilitates greater uptake of nitric oxide and oxygen. This optimal oxygenation supports improved brain function, increased energy levels, and improved cognitive performance. In contrast, mouth breathing can lead to shallow breaths and reduced oxygen uptake.
  1. Reduced stress and anxiety:
  • Deep diaphragmatic breathing, often associated with nasal breathing, activates the parasympathetic nervous system, promotes relaxation, and reduces stress. Mouth breathing, on the other hand, can activate the sympathetic nervous system and contribute to an increased stress response.

In summary, the benefits of nasal breathing extend beyond mere breathing and encompass a holistic approach to health. By utilizing the natural mechanisms of the nose, people can reap a wealth of benefits and promote improved respiratory, cardiovascular and mental health.

So, the next time you breathe, think about which path it takes and check whether you need to work more on your nasal breathing.
