Greetings, beautiful people. I'm amazed that this hasn't been brought up on the forums here yet, or at least not from what I've seen. I guess I'll introduce this perceptual phenomenon to you because you're too lazy to look it up yourselves.
ASMR (short for Autonomous sensory meridian response) is a pleasant "tingling" sensation you can feel in your head, scalp, back, et cetera in response to different stimuli, like receiving personal attention, watching others complete tasks, or by listening to a soothing voice. What triggers it varies from individual to individual so it could be anything. I'm sure that at least a few of you have experienced it already, although you may not have been aware of what it's called or that other people experiences it as well. As someone who often struggles with insomnia, anxiety and stress, I find it to be a great aid for relaxation and sleep. YouTube has its own ever-growing community of ASMR people who role-play events and situations that tend to trigger the response, like receiving a haircut, visiting the doctor's office, et cetera, so give it a try if this sounds cool or interesting to you.
Anyway, I'm curious to know if there are any others here who are familiar with it, and I'd encourage those who are not to check it out on YouTube or something. ASMR is a mystery so it doesn't work on everyone, but I'd say give it a go.
And just to clarify, it's not something that is associated with sixual arousal.
