Oxygen Advantage is a great book. I'd recommend James Nestor's - 'Breath' [0] as a first read, however. I feel like the book has more real world application and I picked up a number of things outside of what I learned studying Hof breathwork. I also studied, prior to both books, with Wim Hof in Poland in 2017 on one of his week long expeditions. The in person experience of group breath work is something to experience if you've never. It's so much different than working on it solo - especially if you're new to any of these methods.
Breath work and cold exposure have been a large part of my life after reading 'What Doesn't Kill Us' by Scott Carney [1]. That was the book that drove me want to experience it first hand.
Commenting on something you haven't read stating that it sounds like something isn't productive. Many of those reviews take statements from the book out of context. For example the one of those comments states the book claims a cure for ADHD. It doesn't. It's an anecdotal reference provided by Dr. Mark Burhenne. Just because a book gathers evidence in support of the books topic doesn't make it "psuedo science".
Wow, you studied with Wim Hof in 2017, thats pretty damn cool! Its funny you say to start with 'Breath' because I was thinking you should start with Oxygen Advantage and then go to Wim Hof, but you sound like you have a much better background for legit recommendations. I had never heard of 'Breath' before. I'll definitely look into it. Is the Wim Hof experience just something one can sign up for? How did you end up there?
I loved reading 'What Doesn't Kill Us', and have been thinking about doing one of the week-long expeditions with Wim Hof. Did you do any prep before going on the trip, or was it your first experience with his breathwork?
