Autonomous Sensory Meridian Response (ASMR) is a term used to describe a tingling sensation that some people experience in response to stimuli, such as sights or sounds. This sensation is often described as starting in the scalp and moving down the neck and spine. It is believed that ASMR can help people to relax and fall asleep, and many people seek out ASMR videos on the internet to help them with stress and insomnia. The exact cause of ASMR is still not understood, but it is thought to be related to the release of certain neurotransmitters in response to triggers such as whispering, tapping, or other soft sounds. While ASMR is not a recognized medical treatment, many people find it helpful in managing stress and anxiety.
