Natural Growth of Nose Hair

Let us come to nose now. Natural growth of hair in the nose is a protector from the diseases of throat, tonsils and lungs. Children who suffer from enlarged tonsils should be trained by the mothers to see that they sleep with their mouths closed. Children sleeping with their mouth open during day or night should be got examined at the earliest and cure of rhinitis or polyps etc., if existing. As a matter of fact, such situations should be taken note of, right from the infancy. We gave no reason to say that hair growth in the nose have no part to play to remove dust particles entering the lungs. If the nasal hair is for the protection of lungs, why not to consider that hair on face also do protection of face and its underneath construction like gums and teeth?
