I got the tingling effect from the Ikea fire video, right at the parts where progress is seen being made towards a fire (The smoke being produced, the ashes, the smolders to the fire itself) and it is an incredible experience. I've also definitely had this experience before with haircuts, although I rather enjoy my hair long so it's a rarity that I get to feel it so often.

Another article, "Autonomous Sensory Meridian Response (ASMR): a flow-like mental state", by Nick Davis and Emma Barratt, lecturer and post-graduate researcher respectively in the Department of Psychology at Swansea University, was published in PeerJ. This article aimed to 'describe the sensations associated with ASMR, explore the ways in which it is typically induced in capable individuals ... to provide further thoughts on where this sensation may fit into current knowledge on atypical perceptual experiences ... and to explore the extent to which engagement with ASMR may ease symptoms of depression and chronic pain'[4] The paper was based on a study of 245 men, 222 women, and 8 individuals of non-binary gender, aged from 18 to 54 years, all of whom had experienced ASMR, and regularly consumed ASMR media, from which the authors concluded and suggested that 'given the reported benefits of ASMR in improving mood and pain symptoms...ASMR warrants further investigation as a potential therapeutic measure similar to that of meditation and mindfulness.'
The writing in this article helped me understand ASMR, but the videos don't seem to be the best examples (it doesn't help that these examples aren't very long). The best examples of what they are talking about to me would have to be the crackling of a fire. Also, whispering in my ear gives me intense tingles, but part of that may be the vibrations off of my ear drum.
Like those who posted before me, I have experienced ASMR for many years. My earliest memories are around the second grade. In my second grade class, we were required to read with partners; however, I was a more advanced reader and would allow my partner to read the entire time if he/she wanted. I would experience intense tingling around the crown of my head listening to him/her read, but I would also experience very intense tingling in the frontal lobe region watching him/her turn the book pages. Around the same time, I would intentionally watch Bob Ross on PBS (like others have mentioned) to take a nap due to the same tingling sensation and calm/relaxation he induced.
Listening to a binaural recording through headphones simulates the binaural hearing by which people listen to live sounds. For the listener, this experience is characterised by two perceptions. Firstly, the listener perceives being in close proximity to the performers and location of the sound source. Secondly, the listener perceives what is often reported as a three-dimensional sound.[33] This means the listener can perceive both the position and distance of the source of sound relative to them.

But the video doesn’t work on me the way it’s supposed to. For many of her fans, Maria’s voice causes a sensation the Internet has dubbed ASMR—autonomous sensory meridian response. Those who get ASMR describe the experience as a tingling inside their heads, or a head rush. Sometimes the sensation extends down their backs or limbs. It’s often referred to as a brain-gasm, but counterintuitively, it’s also supposed to be relaxing, a mellow feeling. Some people watch the videos to help them sleep at night. And even without the tingles, it is sort of relaxing, if you can get past the dissonance of someone whispering in your ear while you scroll through Twitter in your cubicle, or whatever.

Perhaps less obvious, a large majority of the ASMR audience also skews technophile and gamer. People interested in ASMR across the web are more than twice as likely to be in the market for consumer tech products like laptops, mobile phones, and game consoles.8 There's even an ASMR gamer YouTube channel. ASMR may be an antidote to fast-paced video games; research has shown that your brain on video games can heighten your senses.
While the Ephemeral Rift YouTube channel features conventional relaxing videos like trees rusting in the wind or someone shuffling wooden blocks, Paul also experiments by playing characters like Dr. Lampert Schade, a psychiatrist with a lampshade on his head, and Corvus Clemmons, a plague doctor who wears a bird-like steampunk mask. All the videos feature soft soothing sounds and no sudden movements.

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.[citation needed]
The areas that typically work together weren’t firing together as much. Instead, other areas of the brain were getting more involved than usual—areas related to a visual network, for instance. These differences suggest “that instead of having distinct brain networks the way you or I would, there was more of a blending of these networks,” says Smith, who studies the neuroscience of emotion. “It does make intuitive sense that a condition associated with atypical sensory association and atypical emotional association would have different wiring in the brain.”

The ad features the actress Zoe Kravitz using techniques for autonomous sensory meridian response, or ASMR. It is described as a tingly euphoric response, usually starting on the head and scalp, and sometimes spreading down the neck, arms or back. (Michelob ULTRA via AP)
The term ASMR was coined in 2010, but the audio and visual-induced sensation has always existed. If you've ever experienced that cringe-worthy, face-scrunching feeling you get when you hear nails on a chalkboard, ASMR is the exact opposite. It's the chills you get when you hear a beautiful voice singing. It's the prickly sensation when you hear or see something soothing, without having to physically touch it.
“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.
The first study to perform actual brain imaging (fMRI) on subjects currently experiencing ASMR tingles (as opposed to individuals who were merely able to experience the phenomenon) was published in BioImpacts in September 2018. Subjects viewed several ASMR videos with a screen and headphones while inside the MRI scanner. The study found a significant difference in brain activation between time periods when the subject reported tingling (communicated by pressing a button), as compared to time periods when they were watching a video but not reporting tingling (communicated by pressing a different button, to control for brain activation effects caused by merely pressing a button). They concluded that "the brain regions found most active during the tingling sensations were the nucleus accumbens, mPFC, insula and secondary somatosensory cortex", and suggested that these were similar to "activation of brain regions previously observed during experiences like social bonding and musical frisson".[29]
ASMR is usually precipitated by stimuli referred to as 'triggers'.[11] ASMR triggers, which are most commonly auditory and visual, may be encountered through the interpersonal interactions of daily life. Additionally, ASMR is often triggered by exposure to specific audio and video. Such media may be specially made with the specific purpose of triggering ASMR or originally created for other purposes and later discovered to be effective as a trigger of the experience.[4]
