Every Empath is different but I have not seen a common theme between all the ones I know. I myself have a really weird experience with this (as Empaths normally do with everything). I listen to ASMR every night for about 6 months with no reactions until one random day. Now I get it very occasionally with no pattern in sight. I do know Empaths who get it with basically every video they watch and some who just find the sounds of asmr creepy and do not get the tingle at all.
Allen verified in a 2016 interview that she purposely selected these terms because they were more objective, comfortable, and clinical than alternative terms for the sensation. Allen explained she selected the word meridian to replace the word orgasm due to its meaning of point or period of greatest prosperity.[clarification needed]
