Nose vs. Mouth breathing

Nose vs. Mouth breathing

The are a few combinations to choose from, when it comes to Nose vs. Mouth breathing.

A Inhale nose – exhale nose
B. Inhale mouth – exhale mouth
C. Inhale nose – exhale mouth
D. Inhale mouth – exhale nose

Nose was meant for breathing and mouth was meant for eating but there are a few exceptions….

When inhaling through the nose

1 Air is filtered while passing through the fine nasal hair. Dust, pollen and other particles are filtered.

2 Mucus that coats the sides of the nose, functions as a sticky filter for dust, pollen and other particles.

3 Air is sampled with an odder sensor (smell), allowing evaluation of the air inhaled.

4 Air is humidified which facilitates better oxygen absorption in the lungs.

5 Nitric Oxide is added in the nasal cavity to the inhaled air and functions as a disinfectant. Nitric Oxide dilates blood vessels in the lungs, which allows better oxygen absorption.

6 Temperature of the air is regulated so, that it is closer to body temperature, 37 deg. which facilitates better oxygen absorption in the lungs.

Inhaled air-flow is restricted by a narrow passage in the nasal cavity.

When inhaling through the mouth compared to the nose

1 No hair filtering.

2 Moderate filtering by particle adherence to the saliva.

3 Air is humidified by evaporating saliva which dries the mouth. Less saliva in the mouth means, less protection from the teeth against bacteria, less digesting enzymes.

4 Poor temperature regulating.

5 Minimal nitric-oxide added.

Inhaled air-flow not restricted, wide passage.

When exhaling through the nose

1 The exhaled air, heats up the narrow passages in the nasal cavity, allowing better temperature regulation, on the next inhale (heat recycling).

2 The exhaled air, deposits humidity in the nasal cavity, allowing reuse, in the next inhale (moisture recycling).

Exhaled air-flow is restricted by a narrow passage.

When exhaling through the mouth compared to the nose

1 Poor heat recycling mechanism.

2 Poor moisture recycling mechanism.

Exhaled air-flow not restricted, wide passage

Generally speaking, nose breathing is more effective than mouth breathing. Nose breathing is a good choice for breathing with a few exceptions.

1 In case of emergency, during fight or flight (escaping danger), mouth breathing is more practical, because it allows intensive pumping of air in and out of the lungs.

2 When communicating, for example speaking, sound is created by exhaling from the mouth vibrating the vocal cords.

3 Singing or sighing which produces vocal sounds that may give comfort.

4 When overdriving the body during an extreme concentrated physical effort.

4 When exercising specific breathing exercises that produce a positive effect.
