Nestor's book didn't feel right. I don't think he's a crank, or that he's entirely wrong, but the idea that we're breathing wrong feels really unlikely. You don't have to be taught to breathe.

I'm sure that many of the lessons in the book are applicable and there is much to learn. But a lot of it felt like woo, even though I know full well that the author is a well-respected journalist.

I'd really like to hear a sound review from someone who knows the domain better than me.

You can generally see who has sleep apnea just by looking at their face - there's a particular anatomy that comes with heavy mouth breathing and obstructive sleep apnea. If you speak to people who have obstructive sleep apnea, virtually all of them report mouth breathing and mouth dryness.

I think, probably, there's some structural elements that can make mouth breathing more attractive or easier. But, mouth breathing doesn't actually work well for the breathing part. So, for those people, they experience obstructive sleep apnea. For others, they don't. I have spoken to sprinters who have told me that even sprinting is easier to do with nose breathing. But, for others, they cannot even sleep while nose breathing.

So, I definitely believe there are structural elements at play with breathing.

You sure? Haven't read the book / heard of the author. But after I started freediving and training holding my breath (also called static / dynamic apnea lol) and working a lot on related stuff, I realized I was mostly breathing shallow and with my chest, and not deep with my abdomen.

Now I notice it in others. I don't know if it matters in the end. But I breathe a couple of times a minute and then I hear people next to me quickly breathing in and out constantly like a rabbit. Seems stressful?

There's also the fact that using digital devices negatively affects our breathing a lot: https://www.npr.org/2024/06/10/1247296780/screen-apnea-why-s...

Considering how much we use them now it could change the default state significantly, and maybe we do have to consciously relearn the best way to breath.

That’s where I would disagree. Sure there’s a baseline of breathing that everyone does otherwise they’d be dead, but I think the ceiling towards skillful breathing is very high. The difference is more obvious under athletic conditions like if you’re running or biking, just improving your breathing rhythm can improve your performance. There’s even a proper way to breathe if you’re weightlifting, some people might pick it up naturally but I know it’s also commonly taught.

In psychology I’m pretty sure it’s well established and not pseudo science that certain breathing rhythms can increase your energy or decrease your anxiety, I think I read that they teach box breathing to some parts of the military to help keep them calm during missions.

So there’s definitely a range of breathing ability for specific tasks.

I haven't read his book, so I don't know how much of a kook or grifter I would judge this guy to be, and I'm always dubious about things, but I try to remember that even kooks and grifters sometimes (not always!) have genuinely useful things in what they're saying. They might not be the best person to say it, and their suggestions might not always be the best way to make use of the useful bits. But just because someone is trying to make money from spreading their message doesn't make it all BS.

(I think I'm mostly agreeing with you.)
