I've been trying a short guided breathing session the past couple of days and it's crazy how it makes you feel. Also my resting heart rate has already gone down and my HRV is up. Here's the video if you want to give it a try.

Guided Wim Hof Method Breathing

@brycethornton I’ve been doing this off and on for a couple of years. It’s so trippy. His book is pretty interesting too.
@jasonlong Do you track your heart rate and/or HRV? If so, notice any difference?
@brycethornton I _just_ got an Oura ring this week so I’ll be trying that out. I did buy a cheap oximeter back when I started Wim Hof breathing to see what happens to my blood oxygen levels. Not surprisingly, it falls off a cliff during a session.
