I highly recommend the book Breath by James Nestor. The only health/pop sci book I'd recommend. Doing breathwork has increased my HRV by ~10ms and lowered my respiratory rate when I sleep. I no longer snore as a result.

I've read that book and also Patrick McKeown's 'Oxygen Advantage', which also talks about CO2 tolerance and the benefits of Buteyko.

Good stuff honestly, helped me a lot

What breath work do you do every week please?

Reason why I'm asking: the book contains many techniques, and I'm curious about what's working best for people.
