The concept itself has existed before the term ASMR was coined. In 2007, a user under the handle okaywhatever51838 created a thread titled “Weird Sensation Feels Good” on steadyhealth.com, where Jennifer Allen first came across others describing ASMR. In 2008, one user within that forum thread called the sensation Attention Induced Head Orgasm (AIHO). In early 2010, another forum user called it Attention Induced Observant Euphoria.
In my case, I enjoy the most when it occurs naturally in a real world situation. I would suggest you to play some online response related games (color-word match etc.,) for couple of minutes daily and try 1 or 2 ASMR trigger videos at a time. I hope you will get to experience ASMR on some videos at least. Even you play response related games like the color-word match or odd - even number match or the Vowel & consonant related Yes/No kind of games found in the internet for 10 to 15 minutes, I believe you will get at least a basic feeling of ASMR when you are simply resting or when you are calm without having to induce it through videos. Hope this helps. Trust me, it is a really, really good feeling. If it still doesn't work, forget it, no hard feelings. Like I said, I experience it once in blue moon, but never crave for it although I enjoy it when it happens naturally :)
“There needs to be a careful balance between skepticism and open-mindedness when investigating ASMR,” the Sheffield group say. “There is also of course the danger that ASMR videos get picked up by people who might try and use them to market pseudoscience or mental health benefits (without the evidence to support it), and inadvertently spread misinformation about it, which would of course damage the reputation of any genuine research going on,” they add. We’ve already started to see cases of this – just this week, in an interview with the Daily Mail, ASMR video producer Lauren Ostrowksi Fenton claimed that the sensation is produced by oxytocin, which she refers to as “the cuddle hormone, the hugging hormone, or the feel-good hormone”. Besides the fact that there’s simply no evidence that oxytocin is responsible for the sensation, the science behind the claim that oxytocin is a “hug hormone” is itself extremely weak.
"As ASMR has started to come to mainstream attention, researchers have finally begun trying to answer that question. Neuroscientists are now experimenting with fMRIs and electroencephalography to see if the brains of 'tingleheads,' as they are called, are any different than those who don’t tremble at the sight of napkin-folding. They’ve also surveyed tens of thousands of people who say they experience the phenomenon. So far there are intriguing—if limited—findings suggesting that ASMR may relieve some people’s symptoms of stress and insomnia, and that the brains of those who experience it may be organized a little differently."
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.
