ASMR stands for Autonomous Sensory Meridian Response, a term that has gained popularity in recent years, especially on digital platforms like TH-cam and Twitch. It refers to a soothing, often euphoric sensation that people experience in response to certain stimuli, usually auditory or visual. This sensation is typically described as a tingling that starts at the scalp and moves down the back of the neck and spine, but reactions can vary widely from person to person.
