Answer
Breathing through the nose is said to be healthier than through the mouth because the external part of the nose bears two nostrils separated by a cartilaginous septum. The hairs present in the nostrils prevent large particles from entering the respiratory system. So, always breathe through the nose and not through the mouth.
