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.
“One of our main aims is to try to draw attention to ASMR as a topic worthy (and capable) of scientific research, in the hope that it might galvanise future research efforts,” they explain. Of the group, three of them (Emma, Giulia and Tom) experience ASMR, whereas Theresa doesn’t. The study is still in an early stage – data collection has just finished – but this diversity in experience, they believe, is a critical component to their research. “So we starting thinking about how we might first and foremost investigate this phenomenon at the most basic level: what might it take to convince someone who doesn’t experience ASMR that it is a genuine and consistent experience for some people?” they explain. “Theresa doesn’t experience ASMR, and has valuable scepticism of the experience. It adds to the diversity of our research group and the questioning of our approach from a non-ASMR perspective,” they add.
One category depends upon external triggers in order to experience the localized sensation and its associated feelings, which typically originates in the head, often reaching down the neck and sometimes the upper back. The other category can intentionally augment the sensation and feelings through attentional control, without dependence upon external stimuli, or 'triggers', in a manner compared by some subjects to their experience of meditation.
I experience both asmr and frisson so I am familiar with both. They are similar in that they both cause a tingling sensation. Asmr is triggered mainly by physical senses (sight, sound, sometimes smell) and produces a relaxing effect. Like you literally can fall asleep from it. Frisson is triggered by thought and emotion and produces an exciting effect.
While little scientific research has been conducted into potential neurobiological correlates to the perceptual phenomenon known as 'autonomous sensory meridian response' (ASMR), with a consequent dearth of data with which to either explain or refute its physical nature, there is voluminous anecdotal literature comprising personal commentary and intimate disclosure of subjective experiences distributed across forums, blogs, and YouTube comments by hundreds of thousands of people. Within this literature, in addition to the original consensus that ASMR is euphoric but non-sexual in nature, a further point of continued majority agreement within the community of those who experience it is that they fall into two broad categories of subjects.
ASMR can vary from person to person because it’s all about perception, licensed clinical psychologist John Mayer, Ph.D., author of Family Fit: Find Your Balance in Life, tells SELF. “We all perceive experience in a different way even though it is the same experience,” he explains. For example, while one person may find the sound of someone typing comforting (if, say, they had a parent who worked on a computer at home), others may associate the sound with office work and become more stressed when they hear it.
Among the category of intentional ASMR videos that simulate the provision of personal attention is a subcategory of those specifically depicting the "ASMRtist" providing clinical or medical services, including routine general medical examinations. The creators of these videos make no claims to the reality of what is depicted, and the viewer is intended to be aware that they are watching and listening to a simulation, performed by an actor. Nonetheless, many subjects attribute therapeutic outcomes to these and other categories of intentional ASMR videos, and there are voluminous anecdotal reports of their effectiveness in inducing sleep for those susceptible to insomnia, and assuaging a range of symptoms including those associated with depression, anxiety, and panic attacks.
