Summary

Humans are the worst breathers in the animal kingdom—half are habitual mouth breathers, most over-breathe, and our evolutionary trade-off of bigger brains for tighter airways has left us with epidemic levels of sleep apnea, deviated septums, and craniofacial dystrophy. The fix is ancient and simple: breathe through the nose, breathe less, breathe slowly (5.5 breaths per minute hits resonance), and exhale longer. Modern diets that require less chewing have literally deformed our faces and airways. On the other end of the spectrum, deliberate practices like Wim Hof breathing, breath holds, and vagus nerve stimulation can reset the autonomic nervous system, reduce chronic stress, and even modulate fear responses at the level of chemoreception.

Notes

1: The first experiment

1: The worst breathers in animal kingdom

• 1/2 of humans are habitual mouth breathers
• Dis-evolution of human jaw, nasal cavity
• Bigger brain → tighter airway

2: Mouth-breathing

• Goal: always stay in aerobic mode
• Literally reforms face, jaw
• Numerous other benefits

2: The lost art

3: Nose

• Nasal cycling:
• Nose closely linked with genital arousal
• Breathing controls how we think (L/R brain)
• Nose breathing improves circulation

4: Exhale

• Lung size is indicator of health
• Breathe from bottom of lungs

5: Slow

• Breathe to balance O2, CO2 levels
• 85% of weight is lost via breathing
• CO2 levels determine heart rate
• Over-breathing → anxiety etc.
• Resonant breathing: 5.5 breaths / min

6: Less

• Goal: less breathing, longer exhales
• Hypo-ventilation training:
• Asthma: air gets trapped in the lungs

7: Chew

• Modern diet → 10x more cavities
• Cause: less chewing
• ~3/4 people have deviated septum’s
• Sleep apnea
• Craniofacial dystrophy: head tilt to make up for poor airway; 50% of US population
• Chewing → stem cell release

3: Breathing +

8: More, on occasion

• Sympathetic, parasympathetic systems
• Chronic stress → poor blood flow
• Vegas nerve stimulation: fixes ↑
• Wim Hof breathing:
• Holotropic breath work:

9: Hold it

• Two sources of fear: amygdala, chemoreception
• Chemoreception: CO2 levels, regulates breathing
• Constant multitasking → shallow breathing
• 13% of people use SSRIs
• Hold your breath > take a deep breath
• Practicing ↑ → learned control over panic

10: Fast, slow, and not at all

• Indian yogis + Prana (blood flow) control
• Breathe slow, less, thru the nose
• High O2 → electron excitability → health?
• Traditional vs modern yoga
