Why is it important to breathe through your nose than your mouth?

Answer 1

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. Always better whenever possible (deviated septum and small nostrils may make it impractical) nose breathing 24 hours a day is extremely important for those who desire the longest and most healthy life.

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 mucous carries the stimuli to the reflex nerves that control breathing. Mouth breathing bypasses the nasal mucous and makes regular breathing difficult. During sleep, it predisposes one to loud snoring and irregular breathing and can lead to a serious condition called Sleep Apnea and heart conditions.

3. Also, when mouth breathing, the brain thinks carbon dioxide is being lost too quickly and sensing this, will stimulate the goblet cells to produce mucous, slow the breathing and cause constriction of blood vessels. Breathing through the nose also limits air intake and forces one to SLOW down. Proper nose breathing reduces hypertension and stress for most people. Kind of like a speed control (governor) on a car engine.

4. The nostrils and sinuses filter and warm the air going into the lungs. The mouth breather bypasses this. The sinuses produce nitric oxide (NO) which is a pollutant but harmful to bacteria in small doses. Nitric (not nitrous) oxide is one of the very important chemical parts of sexual arousal. It vaso-dilates (engorgement) and plays a part in maintaining erection.

Answer 2

In your nose their are small hair's which prevents dirt from going in your lungs, and in your mouth their is nothing similar.

There are other reasons as well, this is the only one I know :)

Answer 3

the nose acts like a filter because of all the little hairs...

Answer 4

It's not better. It's just that the nose is the natural way of breathing. That's why having Allergies or sinus congestion can really bother you.

Answer 5

The cilia inside your noise get a chance to filter dust and other particulates from the air that you are breathing.

Answer 6

It isn't
