Benefits of Nasal Breathing

Nasal breathing has significant advantages over mouth breathing, particularly in children, as it can enhance physical and cognitive development. This method of breathing promotes proper jaw alignment and facial structure, which can lead to higher IQ levels and better overall health. When breathing through the nose, the tongue naturally rises to the roof of the mouth, supporting the development of the craniofacial structure. Furthermore, nasal breathing improves oxygen efficiency and provides natural filtration through the nasal passages, protecting the body from pathogens.
