Question

Why breathing by the nose is better than breathing by mouth

Answer 1

The air we breathe is first processed through the nose. The nose is a miraculous filter lined with tiny hairs called cilia. The cilia have many functions: they filter, humidify and warm or cool the air (depending on the temperature) before it enters the lungs. It is estimated that cilia protect our bodies against about 20 billion particles of foreign matter every day!

Once it exits the nose, air passes through the mucus-lined windpipe. This is another avenue to trap unwanted particles before they enter the lungs. Next, air enters the lungs, where the oxygen is pumped into the bloodstream and circulated through the body. In exchange, the air leaving the body carries with it carbon dioxide from the cells, a waste material that is expelled through exhalation.

THE BENEFITS OF NASAL BREATHING

Breathing through the nose is the way our bodies were designed. In fact, it’s been said that breathing through your mouth is about as practical as trying to eat through your nose!

According to experts, most people breathe at 10-20 percent of their full capacity. Restricted breathing greatly decreases respiratory function, which in turn decreases energy levels in the body. Since oxygen is our main source of life, and exhalation is the main way to expel toxins from our bodies, poor breathing can contribute to a multitude of health problems, from high blood pressure to insomnia. Poor breathing may even contribute to some forms of cancer: In 1931, Otto Warburg won a Nobel Prize for determining that only oxygen-starved cells will mutate and become cancerous. That should be proof enough to learn how to breathe properly!

Many of us feel stressed out, overworked, and overstimulated during our daily lives, which leaves us in a chronic state of fight or flight response. Breathing in and out through the nose helps us take fuller, deeper breaths, which stimulates the lower lung to distribute greater amounts of oxygen throughout the body. Also, the lower lung is rich with the parasympathetic nerve receptors associated with calming the body and mind, whereas the upper lungs — which are stimulated by chest and mouth breathing — prompt us to hyperventilate and trigger sympathetic nerve receptors, which result in the fight or flight reaction.
