Autonomic Sensory Meridian Response (ASMR) videos are taking the internet by storm and helping people relax and even fall asleep at night. These videos, which use soothing voices and comforting noises, are a kind of “brain massage” that create a spine-tingling, relaxing feeling in the listener. Things like gentle whispers, pouring water, and bat wings flapping can induce this stress-relieving feeling that produces an almost euphoria-like state. These videos, which can be found all over YouTube, are often used by insomniacs to help relax them into a sleepy state. Put one on right before bed and see how this phenomenon can lull you into sleep.
