On that note, you might find the Medlife Crisis' video where he investigates the genre of "people roleplaying as doctors giving you a check-up using an ASMR voice" entertaining, and also enlightening on why some people do like it[0]. Don't worry, it doesn't feature too many actual clips of that.
Participants were guided through pre-recorded audio instructions accompanied with evocative ambient music played through a speaker in the lab to breathe normally for 10 minutes (baseline) then engage in HVB, encouraged by the tempo of the music progressively increasing to the end of HVB. Some examples of the recorded instructions are presented below.
“Mouth wide open, pulling on the inhale, that’s it. No pauses at the top of the inhale, or the bottom of the exhale. Full body breaths. Breathing in to your whole body. Keep breathing. Getting comfortable, finding your rhythm. Keep going. As you’re breathing, it’s now time to let go of any intention you have, of any expectations you have, just focusing on the breath. Keep going. Active inhale, passive exhale. The music is going to keep on rising, so fall into the rhythm and let your breath guide you. Your job is just to keep breathing, pulling on that inhale. Surrendering to the exhale. Keep that breathing circular, that’s it. Keep going. Whatever sensations you’re feeling, let them come, let them rise, enjoy them. Stay focused. Give yourself fully to the breath. It’s your closest friend. It will be with you from the moment of your birth and stay by your side until you die. You can trust it.”
How does this part work? No real music does this so did they make their own for the study? Or do they select songs that change tempo subtley from one to the next?
“Physical Activity, Mindfulness Meditation, or Heart Rate Variability Biofeedback for Stress Reduction: A Randomized Controlled Trial”
I also misremembered, breathwork wasn't directly looked at as an intervention method, but I believe the HRV biofeedback did involve it to some degree.
As is tradition with these kinds of things.
Is it just me or is this commonly discomfort-inducing? Hyperventilation is so associated with anxiety and panic that I don’t see how anything remotely pleasant can come of this. Assuming one’s acid-base balance and oxygenation are normal, I don’t quite see the point here.
