Interesting. I tried it for a bit over a minute (8 cycles), but then I had to stop. I get really dizzy unless I take breathing breaks after outbreaths. Will try again to see where this goes, thanks! Really like the simplicity.
11 cycles this time. Went a bit further into the dizziness, since I was more prepared for it this time. Unsure whether it makes sense to just stay with the dizziness as long as I can, or whether I should stop earlier. Probably either is fine as long as I am somewhat confident about it?
Thank you for sharing your experience. Try more shallow breathing rather than modifying the frequency/timing, which is the whole point of this approach :)
