What are the Advantages of Nasal Breathing?

Breathing through nose is healthier because it is a natural process. The air which is inhaled contains dust, bacteria, etc., get filtered in the nose. Thus the air which goes into lungs is cleaner. The conchae of the nose also filter and warm up the air.

1. At rest, breathing occurs about 14-18 times per minute in a normal man, being more in children.

2. Mammals have negative pressure breathing as it allows them to eat and breathe at the same time.

3. In human female, thoracic breathing is more predominant. Artificial Respiration

Persons who have stopped breathing because of drowning, electric shocks, or smoke inhalation may be subjected to artificial breathing until their own breathing can be initiated. A variety of methods of artificial respiration have been practiced over the years, but the mouth to mouth breathing is very common.
