Breathing through the nose has many benefits. Breathing through the mouth, many negatives. There are some researchers who believe that mouth breathing and associated hyperventilation causes or exacerbates asthma, high blood pressure, heart disease, and many other medical problems.


1. The lungs are a primary source of our energy level. They extract oxygen from the air we breathe primarily on the exhale. Because the nostrils are smaller then the mouth, air exhaled through the nose creates back pressure when one exhales. It slows the air escape so the lungs have more time to extract oxygen from them. When there is proper oxygen-carbon dioxide exchange, the blood will maintain a balanced pH. If carbon dioxide is lost too quickly, as in mouth breathing, oxygen absorption is decreased.

2. Afferent stimuli from the nerves that regulate breathing are in the nasal passages. The inhaled air passing through the nasal mucosa carries the stimuli to the reflex nerves that control breathing ...more

Mouth is not connected to lungs, it is connected only to one's stomach. While eating -that too very spicy food- if you laugh, food particles enter the breath pipe and you struggle- have you ever suffered that! There is a one way valve which links breath pipe and food pipe. This valve is always shut but opens if you laugh loudly. You may ask if it always shut, why such construction. That is the beauty of HIS creation. Supposing you are not able to consume food through mouth for any reason, you can insert a pipe through your nostril -put the other end of the pipe in a bottle & suck the liquid from the bottle to go to your stomach. What a master HE is! When the lungs empty this valve closes to prevent polluted air in reaching the breath pipe.
