Because this phenomenon was only recently given a name, the science backing it up is virtually nonexistent. Of the minimal research, one study published in PeerJ found that ASMR results in “temporary improvements in symptoms of depression and chronic pain,” while another study published in the International Journal of School & Educational Psychology determined that the phenomenon can soothe stress and help insomniacs. Basically, ASMR makes people happy and healthy.
I forgot to mention and may be interesting to people curious about such effects. One "mantra" or intention that I have assimilated in silence and often keep repeating softly inside is "Bless All Beings". There's a famous Sanskrit mantra that basically says the same, but English also works, and may work better for Westerners as intentions need to have meaning, not just repeating syllabuses without understanding or intention.
I get this response, but I don't always like the feeling. If someone pulls down a projector screen, like those found in classrooms, i get a tingling sensation all over my body but I don't associate it with a pleasurable feeling. It's almost like nails on a chalkboard. I feel the same way about listening to a violin. The whispering though is a pleasurable ASMR response for me.
