Aside from the pleasurable sensation that ASMR offers there are a range of other benefits. Many intentional ASMR videos are essentially forms of guided meditations, meditating regularly has been shown to reduce stress levels and aid concentration among many other things. For a lot of people ASMR is a gateway to developing an ongoing meditative practice.
The concept itself has existed before the term ASMR was coined. In 2007, a user under the handle okaywhatever51838 created a thread titled “Weird Sensation Feels Good” on steadyhealth.com, where Jennifer Allen first came across others describing ASMR. In 2008, one user within that forum thread called the sensation Attention Induced Head Orgasm (AIHO). In early 2010, another forum user called it Attention Induced Observant Euphoria.
In the limited, small studies that have been done investigating ASMR, there do appear to be brain abnormalities in people who experience ASMR, though this is far from confirmed. But some studies did find that people who experience the phenomenon appear to have brains that are wired differently when it comes to the areas that react to sensory perception. Instead of two sensory areas having a clear connection in their brain, a tinglehead’s sensory areas of the brain appear to blend together to some degree. Some neurologists who have studied the phenomena even think ASMR could be related to the bizarre condition of synesthesia, where a person can hear smells or see music.
Among the category of intentional ASMR videos that simulate the provision of personal attention is a subcategory of those specifically depicting the "ASMRtist" providing clinical or medical services, including routine general medical examinations. The creators of these videos make no claims to the reality of what is depicted, and the viewer is intended to be aware that they are watching and listening to a simulation, performed by an actor. Nonetheless, many subjects attribute therapeutic outcomes to these and other categories of intentional ASMR videos, and there are voluminous anecdotal reports of their effectiveness in inducing sleep for those susceptible to insomnia, and assuaging a range of symptoms including those associated with depression, anxiety, and panic attacks.
