Episode notes
From Stoicism To Breathing Teacher
- Rubén Sosa discovered breathing through meditation and stoic practice before diving into formal breathing methods.
- He turned that curiosity into five-plus years teaching functional breathing to friends, family and students.
Breath Rate Linked To Lifespan
- Ancient practices viewed breath count as a measure of life and longevity across species.
- Faster breathing correlates with shorter lifespans in many animals, highlighting breath rate's physiological importance.
CO2, Not Oxygen, Drives Breathing Effects
- Blood oxygen stays high (95–99%) so breathing practices mainly change carbon dioxide levels, not oxygen saturation.
- CO2 controls respiratory drive, vasodilation and vagal tone, so CO2 tolerance is central to breathing effects.
