This was an excellent assessment of our breathing, the apparatus of our mouths to teeth to the nasal cavity. You will never think about breathing the same ever again.
Though only a few of these are mentioned in the inter\view, it is a well-known and established fact that breathing through your nose has greater health effects on bodily functions and bodily form.
Quickly, Healthline offers a shortlist of the benefits of breathing through your nose and problems of breathing through your mouth.
Yet, breathing primarily through your mouth is associated with some health risks. With mouth breathing, your mouth loses moisture, which can cause dry mouth. It could also increase your risk of inhaling unfiltered air, of allergic reactions to allergens, asthma, bad breath, tooth decay, gum inflammation (gingivitis), snoring, sleep apnea, teeth or jaw abnormalities
Nose breathing is beneficial primarily because it allows your nasal
cavities to
1) Reduce exposure to foreign substances
2) Humidify and warm inhaled air
3) Increase airflow to arteries, veins, and nerves
4) Increase oxygen uptake and circulation
5) Slow down breathing
6) Improve lung volume
7) Help your diaphragm work properly
8) Lower your risk of allergies and hay fever
9) Reduce your risk of coughing
10) Aid your immune system
11) Lower your risk of snoring and sleep apnea, and
12) Support the correct formation of teeth and mouth
In the course of this interview, Nestor references a couple of people and their studies that I'd never heard of. One was Swedish breathing expert, Anders Olson.
A second was Yandell Henderson at Yale, who studied the benefits of CO2, you know, the very thing that the climate changers or climate alarmists or global warmers or globalists are trying to persuade force all of us to get less of. But Henderson's study at Yale is particularly interesting. According to Encyclopedia.com
Henderson’s greatest contribution to science was probably in the practical application of his ideas. He introduced the technique of administering a mixture of carbon dioxide and oxygen, instead of only oxygen, as a method of resuscitation. His conviction that carbon dioxide stimulated circulation and respiration led him to use carbon dioxide-oxygen inhalation as treatment for carbon monoxide poisoning, surgical shock, asphyxia of newborn babies, and similar conditions. This technique proved very successful and saved countless lives. Henderson also became involved in the design of mine rescue apparatus and in the fixing of ventilation standards for the Holland Tunnel. During World War I he supervised the production of gas masks for the Chemical Warfare Service of the U.S. Army.
One of Nestor's early references in the interview was to freediving. Rushcult explains that freediving is
any aquatic activity that involves holding your breath underwater”. Some examples of activities in water that would hence be a form of freediving include free-dive photography, breath-held spearfishing, apnea diving and synchronized swimming.
The host mentions diaphragmatic breathing. The words give you a clue, but specifically, it involves rapid breathing, a lot like the Wim Hof breathing method. The Cleveland Clinic explains that
Diaphragmatic breathing is intended to help you use the diaphragm correctly while breathing to. It helps strengthen the diaphragm. It decreases the work of breathing by slowing your breathing rate. It decreases your demand for oxygen. And you use less effort and energy to breathe.
At the 36-minute mark, Nestor mentions Wim Hoff's breathing method. What is that?
Sitting at home, you can easily try it for yourself. While sitting in a comfortable place, take 30 quick, deep breaths, inhaling through your nose and exhaling through your mouth. Then, take a deep breath and exhale; hold until you need to breathe in. Inhale again, as deep as you can, and hold it for 10 seconds. Repeat as many times as you like.

Since the fact that the brain-gut connection has been overwhelming established, even since Shakespeare's days, it is important to know that correcting your breathing will more than likely fix gut issues.
