I had ASMR before it was popular. Whenever I got a haircut, I got those weird chills from my head down my spine, and I felt very comfortable and relaxed.
When I have trouble falling asleep, Haircut Harry is often my late-night companion. Something about the sounds in the videos, along with an appreciation for masters of their craft, calms me.
Maybe barbershop videos work for you, maybe not. My wife seems to like rug cleaning videos.
But if you are having trouble falling asleep, maybe try Sleep Baseball.
From the site:
Northwoods Baseball Sleep Radio is a full-length fake baseball game. There is no yelling, no loud commercials, no weird volume spikes. Fans call it “baseball radio ASMR”.
It is the perfect podcast for sleeping or relaxing, if you’re into that kind of thing.
It even has a nice write-up in the New Yorker.
