Answer 2

The benefits of breathing through your nose are many; I will just mention a few of them here.

1) Air inhaled through the nose is warmed and moistened, so it does not irritate the sensitive airways.

2) Air exhaled through the nose reabsorbs moisture efficiently, reducing dehydration.

3) Air inhaled through the nose is filtered, (spun as it rushes round specially designed structures the concha or turbinates, so any particles – allergens, microbes – stick to the mucus lining of the airways where they are destroyed by enzymes and gases with anti- microbial properties).

4) Nasal breathing promotes good oral health. Mouth breathing causes a drying out of the gums, increases the acidity in the mouth encouraging both cavities and gum disease.

5) Breathing through the nose encourages good facial development and straight teeth. A closed mouth, with the tongue where is should be, in the roof of the mouth for most of the time, can help the jaw grow enough to accommodate all the teeth.

6) Nasal breathing helps reduces snoring and sleep apnoea and ensure a good night’s sleep.

7) Breathing through the nose helps regulate the volume of air breathed, so that it can effectively match the body’s oxygen needs.
