(#200) How Nasal Breathing Counteracts Gravity

“In this work, we have demonstrated that nasal breathing counteracts the effects of gravity on pulmonary blood flow in the upright position by redistribution of blood to the nondependent lung regions.”

Sánchez Crespo et al. (2010)

 

It’s Friday, so a new 411 was just released. 

 

In this one, you’ll learn:

  • How nasal breathing redistributes blood flow (up to 24%) in the lungs to counteract gravity

  • How nitric oxide (NO) is the essential component of this blood flow redistribution

  • How nasal NO may have been an evolutionary adaption allowing us to walk upright

Enjoy your weekend,
