Well I know it may be cognitive bias as someone pointed out but I think it also had to do with the book Breath by James Nestor. Got pretty heavy press as it came out early in the pandemic. But mindfulness and meditation are being pushed pretty hard lately.
It's good for a soft introduction to the space, in that it informs you of many things you might not have ever heard about... after which you would need to go track down the references and expand on any particular sub-topic which seems more relevant to you.
I recommend it to many people as a way of demonstrating that "hey, a few simple breathing tweaks might be really helpful".
