10 Percent More, Rich Inner Core, and My Kind of Equanimity

Published December 12, 2022

4 Thoughts



1. The Famous 10-18% Nasal Breathing and Oxygenation Study

We here show that arterial oxygenation is improved in healthy awake subjects during nasal breathing as compared with mouth breathing.

- Lundberg et al. (1996)

Two take-homes from this oft-cited paper:

  • Nasal breathing increased tissue oxygenation by ~10% compared to mouth breathing in 6 of 8 healthy people.

  • Adding nasal air to a ventilator increased arterial oxygenation by ~18% in 6 of 6 mechanically ventilated people.

Deep dive of this paper:

This one was packed with fascinating results. If the take-home is all you need, stop there. But if you’re a serious breathing nerd, this one is a must-read/listen-to Science 411 (just released on Friday).

2. Use Your Diaphragm for Less Stress & Better Cognition

Diaphragmatic breathing can directly lower cortisol levels, reducing the negative physiological responses to stress and improving cognitive function.

- Patrick McKeown, The Breathing Cure

Sounds good to me. If we combine that with thought #1, we can also increase oxygenation while we’re at it 👏

3. Exercise Your Rich Inner Core for More Benefits (beyond abs or diaphragm)

More and more, I became convinced that our bodies are wired to benefit from exercising not only our muscles but our rich inner, human core — our beliefs, values, thoughts, and feelings.

- Herbert Benson, MD, Timeless Healing

What better way to exercise and express those than a daily self-care ritual? I like 20-30 min of morning breathing & gratitude, but anything you do to connect to your values, beliefs, and feelings will do.

Have fun exercising your rich inner core, this week 🙏

4. Equanimity

Equanimity is when the breather realizes they are the breath.
