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.

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.
