James Nestor - Breathing for Better Health (Ancestral Health Today Episode 003)

In this episode of Ancestral Health Today, we bring you a conversation with James Nestor.
James Nestor is a science journalist and author of the bestselling book Breath, which was on the New York Times bestseller list for 18 weeks, and won the a 2020 prize for Best General Nonfiction. James also wrote a book on free divers who test their limits by diving to the ocean floor without oxygen tanks, and he's published articles in Scientific American, The New York Times, The Atlantic, and Surfer's Journal. He suffered from some respiratory conditions and spoke to medical researchers, athletic trainers, and practitioners of different religious and meditative traditions, trying to understand the connection between breathing and health.
James spoke at the Ancestral Health Symposium conferences in 2021 and 2022.
In today's episode, we start by covering the physiology of breathing and how it influences oxygen, carbon dioxide and the autonomic nervous system. We'll get into some physiological experiments that James and a colleague took part in with leading doctors at Stanford, and how changing breathing lowered blood pressure, reversed apnea and other health issues. We'll then look the how the changes in diet and lifestyle in modern society has actually changed the shape of the human skull and our airways, impairing our ability to breath correctly. Finally, we'll look at some advanced breathing practices that can improve health and combat anxiety.

Excellent discussion. Nestor's information has the added benefit of being true, and it's easy to verify for oneself.

'Ancestral' children most likely didn't go from breast milk to half-rotten chewy leathery meat, or whatever was around. Their mothers would chew (process) the available food for them. Babies are born with a few teeth and not really setup to eat whatever the adults were eating. Not to mention that child mortality must have been through the roof then (heck, it was high a couple of hundred years ago).

James looks extremely healthy for his age

[@ferrisberlin6583]

How old is he?

[@Edelwiess1066]

I'd love to know what he would say about the carnivore diet. Lion diet. That's what i have been on for over a year and it has done me a world of good in several areas of my health.

👍

[@JackApfel]

He mentiones some guy that followed up on Weston Price called Robert Cortini or so? What is the name of that person, I couldn't understand it.

[@StanislavKozlovsk]

Pretty hard to do 4-5 seconds of inhale and exhale each!

[@Tyrannocaster]

Really? I don't find it hard at all. I certainly don't have any special training so I am surprised by your comment.

[@scoobtoober2975]

Warm into it. 2x2x2x2 in hold out hold. it can show your stress level. work up by one second increments. try taking a cold shower with the same rhythm. You will quicken your rate of in and out and less hold time.

I have 1 meter and 80 centimeters, and thin !! Am i the type of person who would benefit by breathing ina a 7 to 8 breaths ? Thank you
