The past few years I have been gradually starting to use ASMR to relax. I have had increasing bouts of anxiety and can't take too many kinds of medications since I am on blood thinners. So I rely on different relaxation methods to get me through.
I am fond of shoe and purse tapping but can't take mouth noises. Actually most tapping sounds seem to be the best fit for my ears. Maybe the occasional crinkling here and there. Perhaps even some whispered talking but I prefer just the sounds.
Some of these folks really go out in their productions. It's been amazing watching the evolution over the years.
