I would probably end up mainly focusing on how cringey this prompt is.

Hah, you remind me of how I basically had to learn to ignore the "wellness instructor ASMR" voice used in audio guides to yoga, mindfulness, and so on. And of my sister who did her biology PhD on breathwork as an intervention method for pregnant women, which also involved selecting and sending out mindfullness audio-guides of that kind to pregnant women who were part of the research. By the end of it she swore that if she ever had to listen to someone using that kind of voice again she'd lose her mind.

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.

What did your sister study specifically? It was not hyperemesis gravidarum by chance, was it?
