In addition to the information collected from the 475 subjects who participated in the scientific investigation conducted by Nick Davies and Emma Barratt, there have been two attempts to collate statistical data pertaining to the demographics, personal history, clinical conditions, and subjective experience of those who report susceptibility to ASMR.
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.
ASMR doesn’t work for everyone and it can be tough to imagine the sensation if you don’t experience it first-hand. For most people who do experience it, the blissful tingling starts up in the scalp and then makes its way through the body to the arms and legs. And as a result, it can trigger a feeling of relaxation before bedtime, which can help you overcome insomnia. The audio/video segments are long—in fact, some last up to an hour. They are lengthy so that you can keep watching or listening to them until you drift off.
Many of those who experience ASMR report that some specific non-vocal ambient noises are also effective triggers of ASMR, including those like the sound of rain, fingers scratching or tapping a surface, the crushing of eggshells, the crinkling and crumpling of a flexible material such as paper, or writing. Many YouTube videos that are intended to trigger ASMR responses capture a single person performing these actions and the sounds that result.
