7 Key Concepts
Nasal Breathing
Breathing through the nose humidifies, pressurizes, filters, and conditions air, making oxygen absorption more efficient in the lungs. It also helps prevent the loosening of throat tissues, reducing snoring and sleep apnea.
Mouth Breathing
Breathing through the mouth bypasses the nose's filtering and conditioning functions, exposing the lungs to raw air. It can loosen throat tissues, increasing susceptibility to snoring, sleep apnea, and other respiratory problems.
Masticatory Stress
The physical act of chewing, particularly tougher foods, is vital for the proper skeletal development of the face and jaw, especially in childhood. Insufficient mastication can lead to smaller mouths, crooked teeth, and constricted airways.
CO2 Balance
Carbon dioxide is crucial for oxygen delivery within the body. Over-breathing reduces CO2 levels, leading to vasoconstriction and making it harder for oxygen to offload from the blood to tissues, which can worsen conditions like asthma.
Autonomic Nervous System Control
Through conscious breathing practices, individuals can influence the 'automatic' functions of their nervous system, shifting from a stressed (sympathetic) to a relaxed (parasympathetic) state, which impacts immune function, digestion, and overall physiological balance.
Coherence (Physiological)
A state achieved through slow, rhythmic breathing where the body's systems, particularly heart rate and breathing, synchronize into efficient, smooth sine waves. This state optimizes bodily functions, improves mental clarity, and supports healing.
Email Apnea
An unconscious habit, common among office workers, of holding one's breath or breathing dysfunctionally while focused on digital tasks like emails or Zoom calls. This triggers a stress response, similar to sleep apnea, affecting neurological and physical health.
10 Questions Answered
Breathing practices have been studied and written about for millennia across cultures, but these discoveries were often forgotten and rediscovered. Modern science now provides instruments and interest to prove how these ancient practices work.
The foundation of healthy breathing involves breathing through the nose, exhaling more, and breathing more slowly and less frequently, aligning with metabolic needs.
Nasal breathing humidifies, pressurizes, filters, and conditions air for better oxygen absorption, while mouth breathing exposes lungs to unfiltered air, loosens throat tissues, and increases risk of snoring and sleep apnea.
Yes, the maxilla (upper jaw bone) can be remodeled at almost any age. Practices like specific chewing techniques and palate expanders can increase airway size and improve breathing.
Breathing less frequently and more deeply allows air to reach the lower lobes of the lungs where oxygen absorption is highest, and helps maintain a crucial CO2 balance, which is necessary for oxygen to offload from blood to tissues.
Slow, efficient breathing helps reduce inflammation by activating the parasympathetic nervous system, improves CO2 balance (beneficial for asthmatics), and can re-establish vagus nerve connectivity, which is vital for organ function and stress regulation.
Researchers can predict a panic attack an hour before it occurs by monitoring respiratory rate and CO2 levels. Slowing down breathing can abate panic attacks by allowing CO2 levels to normalize.
Email apnea is the unconscious habit of holding one's breath or breathing dysfunctionally while engaged in digital tasks. It mimics a stress response, leading to increased adrenaline, blood sugar spikes, fatigue, and potential long-term neurological and physical problems.
Nasal breathing allows athletes to perform harder with a lower heart rate, increases oxygen efficiency, and helps the body operate in an aerobic state for longer, improving endurance and recovery.
These intense, conscious over-breathing practices purposely stress the body for a short time to stimulate the autonomic nervous system and immune system, helping to regain balance and potentially alleviate symptoms of autoimmune diseases.
31 Actionable Insights
1. Prioritize Correct Breathing for Health
Prioritize breathing correctly, as it is fundamental to health, even more so than diet and exercise, for achieving true well-being.
2. Establish Foundational Breathing Habits
Consistently breathe through your nose, exhale more, breathe less frequently, and breathe slowly to establish a foundational practice for universal health benefits.

Improve vagus nerve connectivity through specific breathing and calming practices to enhance communication between organs and the brain, potentially resolving various physical and mental health issues.
11. Abate Panic Attacks by Slowing Breath
If prone to panic attacks, practice slowing down your breathing to increase CO2 levels, which can help abate an impending attack.
12. Combat “Email Apnea” at Work
Be aware of “email apnea” (holding breath or dysfunctional breathing while working) and consciously remind yourself to breathe regularly and calmly throughout the workday to prevent stress and fatigue.
13. Never Outwork Your Breath
During physical activity, ensure you can maintain correct breathing (preferably nasal breathing); if you find yourself breathing dysfunctionally, slow down and gradually build back up.
14. Recognize Biological Roots of Fear
Recognize that fear and anxiety can stem from physiological states, not just external events, and use breathing techniques to alter your internal biology and reduce these feelings.
15. Chew More for Jaw Development
Incorporate tougher, natural foods into your diet and chew more to support proper skeletal development of the mouth and jaw, which can improve airway health.
16. Chew One Side for Relaxation
Chew specifically on one side of your mouth to tone your airway, develop your face, and stimulate a parasympathetic (relaxation) response, aiding digestion and bone growth.
17. Use Mouth Tape for Nasal Sleep
Use a small piece of tape on your lips at night to train your mouth shut, promoting nasal breathing during sleep, which can reduce snoring and sleep apnea and increase oxygen intake.
18. Improve Digestion with Pre-Meal Breathing
Practice calm, relaxed breathing for a couple of minutes before meals to improve digestion and reduce adverse reactions to food, especially if you experience gut issues.
19. Utilize Transition Times for Calm
Utilize transition times (e.g., before meals, between work and home) for short breathing practices (e.g., 2 minutes of nasal breathing) to shift your body into a relaxed state, improving digestion and overall well-being.

4 Protocols
Mouth Taping for Nighttime Nasal Breathing
James Nestor (learned from Ann Kearney at Stanford)- Use a tiny piece of tape, about half the size of a postage stamp.
- Place it directly across your lips to gently train your mouth to stay shut while sleeping.
Mastication for Airway and Jaw Development
James Nestor (based on research from Dr. Ted Belfort and Scott Simonetti)- Incorporate more chewing into your diet, opting for tougher, natural foods.
- Chew on one side of your mouth at a time, then switch to the other side, to promote a parasympathetic (relaxation) response and aid bone growth.
Daily Slow Breathing Practice
James Nestor (referencing ancient practices and researchers like Dr. Patricia Gerbarg and Dr. Richard Brown)- Breathe exclusively through your nose.
- Exhale for a longer duration than your inhale.
- Aim for a breathing rate of approximately 6 breaths per minute (e.g., 5.5 seconds inhale, 5.5 seconds exhale).
- Practice for a few minutes daily, even while doing other activities.
Nasal Breathing for Athletic Performance
James Nestor (quoting Patrick McKeown)- Breathe through your nose during all exercise.
- Do not work out harder than you can maintain correct nasal breathing; slow down if you find yourself needing to breathe through your mouth.
