While many of us might relax by reading a good book or working out at the gym, there's a large number of people who have turned to watching YouTube videos featuring some of the most ordinary — but occasionally strange — behaviors. (See also: Yoga Tricks to Help You Relax)
The videos seek to trigger a mysterious phenomenon known as Autonomous Sensory Meridian Response, or "ASMR." In short, it is a tingly sensation in the back of the head and down the neck. Those who claim to experience ASMR say it is triggered by a wide variety of things, from deliberate hand movements to soft voices or sounds, including fingernail tapping or hair brushing.
"For me, one of the biggest things is crinkles and crinkly bags," said Lindsay Ragone, a television editor in Canada who claims the sensation has helped her address a sleeping disorder. "I've watched hundreds and hundreds of these videos, if not thousands." (See also: Sleep Better With Calming Words)
Ragone is currently producing a film on the topic, "Braingasm," featuring interviews with people who produce these videos on YouTube. Another documentary, "Tingly Sensation," is also in production and has received more than $11,000 in funding through Kickstarter.
At this point, there is no scientific evidence that ASMR is a real thing, though at least one researcher at Dartmouth is exploring the phenomenon. And Ragone said there is some debate among YouTubers about which videos actually trigger ASMR and which offer a more general feeling of relaxation.
Either way, Ragone noted that some ASMR-themed YouTube channels feature tens of thousands of subscribers, with some individual videos notching millions of views. And the comments on YouTube are almost universally positive, with users praising video producers for helping them deal with everything from sleep problems to stress and even depression.
"Generally, the reason people get into these videos is that they come across them accidentally one night on YouTube and realize 'Oh my God, that's that thing I felt, and I didn't know how to describe it,'" Ragone said. "There are people who say, 'I didn't know this was a thing. I've had this my whole life.'"
In general, ASMR enthusiasts have remained something of an underground community, though the phenomenon was the subject of a story on NPR's This American Life earlier this year. (See also: Free Ways to Learn Something New)
