I just use it as white noise to help me stem the tide of anxiety, as a background thing, without actually looking at the videos.
but I also use stuff like art restoration or that japanese dude who makes knives out of anything for the same purpose so I guess that's kinda like what these people get from those videos of a sexy lady crinkling paper?
also there's a few ASMR guys who just do the most dad shit you've ever seen
