Breathing provides our body with much-needed air (oxygen). It not only helps us to assimilate what surrounds us, but also to absorb some "fragments of life", to understand them and, in turn, devotes a part of itself (CO2).
Nose breathing in particular, since we breathe through our noses and not our mouths, is necessary for many things and for many different reasons. First, our bodies function effectively in a state of balance, alternating between action and relaxation, daydreaming and rational thinking. This balance is affected and can even be controlled by nasal cycle.List following reasons why nose breathing is good for you:
The right nostril is "airbag"
Inhalation mainly through right nostril will speed up blood circulation. It also causes your body to heat up, causing stress, raising cortisol levels, blood pressure, and heart rate.
Breathing through right side of nose activates sympathetic nervous system, which puts body into a state of heightened alertness and alertness. It also sends more blood to opposite hemisphere of brain, especially prefrontal cortex, which is involved in logical decision making, speech, and calculations.
The left nostril is "brake"
The left nostril is closely linked to parasympathetic nervous system, which lowers body temperature and blood pressure, cools body, and reduces anxiety. Breathing through left nostril diverts circulation to other side of prefrontal cortex, area responsible for creative thinking, emotions, and formation of mental abstract thoughts.
Researchers at University of California San Diego recorded breathing patterns of a woman with schizophrenia over past three years and found that her left nostril was "more" dominant. They theorized that this breathing habit overstimulated "creative" right hemisphere of her brain, causing her imagination to spiral out of control. The researchers taught her to breathe through her "logical" right nostril in a few sessions, which made her hallucinate much less.
"The big secret of life"
Although we Eastern cultures have been using nasal breathing for centuries, it wasn't until 19th century that many people in West began to learn this useful technique. All thanks to artist and explorer George Catlin, who spent six years traveling Great Plains documenting lives of 50 Indian tribes.
One of tribes he encountered, including Lakota Sioux, Omaha, Cheyenne and Blackfeet, all in Missouri, were mysterious Mandan who were 6 feet tall and lived in a bubble house. Many of them have blue eyes and Snow White hair. Until then, no one of European origin bothered to contact Mandan or other tribes, let alone talk to them, study and live with them, and learn about their beliefs and traditions.
Tribal people who have never been to a dentist or a doctor have perfectly straight teeth. According to Kathleen, they are "like piano keys with regularity". The tribes attributed their exuberant health to drug, which Kathleen called "life's great secret." this secret? Nasal breathing.
The Native Americans explained to Kathleen that breath inhaled through mouth weakens body, distorts face, and causes stress and disease. Nasal breathing, on contrary, strengthens body, makes face beautiful and prevents diseases.
"The air entering lungs is different from air entering nostrils, just like distilled water is different from water in a regular pool or frog pond"
Helps your sinuses and helps you sleep
More than a century later, Northern California dentist and sleep researcher Mark Buren began to study relationship between breathing and sleep. He found that former caused periodontal disease and bad breath, and believed that this was main cause of tooth decay, even more harmful than sugar, poor diet, or poor hygiene. He also found that mouth breathing is one of causes of snoring and sleep apnea. So he advises his patients to tape their mouths at night.
The health benefits of breathing through your nose are undeniable. One of them is release of large amounts of nitric oxide from sinuses, a molecule that plays a key role in increasing blood circulation and saturating cells with oxygen. Nitric oxide levels can seriously affect immunity, weight, mood, and even sexual function.
Nitric oxide can be increased 6 times by nasal breathing alone, and oxygen can be absorbed 18% more than by mouth breathing. Mouth bandages helped a 5-year-old patient overcome ADHD, a disorder associated with difficulty breathing while sleeping. He helps him and his wife deal with snoring and breathing problems. Hundreds of other patients have reported similar benefits.
Laboratory tests have shown that nitric oxide improves survival of mammalian cells infected with coronavirus. Inhalation of nitric oxide is being studied as a therapy to help restore lung function and enhance immune response in patients with severe symptoms of COVID-19.
