NBC News: "Why some researchers say 'brain tingles' could be the next big trend in relaxation" — "Have you ever felt a static-like or tingling sensation on the top of your head when someone brushes your hair or whispers to you? The feeling may travel down your arms and your spine, and it likely makes you feel very relaxed. Some call it a 'sparkly' feeling, and it might happen when you hear someone crinkle a piece of paper or when someone traces a word on your back.
From my experience with ASMR videos in the last three weeks, I’ve never had one trigger the kind of episode I had with my uncle. However, that doesn’t mean the ASMR videos had no benefits. The biggest, I’ve found, is that the right ASMR video works like a charm in sending me to sleep. In fact, ASMR videos seem to be better at sending me to sleep than most sleep hypnosis videos I’ve found.
I have repeatedly tried listening to ASMR YT videos, however, I have found them actually highly irritating and not calming. The whispering (extreme soft speaking) cause me great annoyance. You are right in that not all people respond to ASMR videos in the same manner. However, a back massage with calming music, listening to powerful worship music, dialogue of a spiritual nature, sitting by water and meditation on Scripture are triggers for this sensation.
In addition to the effectiveness of specific auditory stimuli, many subjects report that ASMR is triggered by the receipt of tender personal attention, often comprising combined physical touch and vocal expression, such as when having their hair cut, nails painted, ears cleaned, or back massaged, whilst the service provider speaks quietly to the recipient. Furthermore, many of those who have experienced ASMR during these and other comparable encounters with a service provider report that watching an "ASMRtist" simulate the provision of such personal attention, acting directly to the camera as if the viewer were the recipient of a simulated service, is sufficient to trigger it.
