Thanks for responding Amelia, I have experienced this sensation since childhood and only recently found out it was an actual thing. Though from what I understand not everyone experiences it. I have read that it can help with insomnia and as I don't like taking sleep meds I was interested in hearing if anyone has found it to be useful for that.
Zeb - ASMR is a particular sensation felt as a pleasant tingling feeling usually on the scalp or shoulders, it is very relaxing and can be triggered by certain sounds or activities. If you have ever experienced this you would recognize the description immediately.
