Trigger your shivers: Autonomous Sensory Meridian Response

Interesting, fun and relaxing material found on radio WFMU's blog about Autonomous Sensory Meridian Response (ASMR) 

ASMR is a " physical sensation characterized by a pleasurable tingling that typically begins in the head and scalp, and often moves down the spine and through the limbs" 

"Most ASMR episodes begin by an external or internal trigger, and are so divided for classification. Type A episodes are elicited by the experiencer using no external stimuli, and are typically achieved by specific thought patterns unique to the individual. Type B episodes are triggered involuntarily by an external trigger, via one or more senses, and may also involve specific thought patterns associated with the triggering event. Both types of triggers vary between individuals, but many are common to a large portion of ASMR enjoyers.

Common external triggers:

• Exposure to slow, accented, or unique speech patterns
  
• Viewing educational or instructive videos or lectures
  
• Experiencing a high empathetic or sympathetic reaction to an event
  
• Enjoying a piece of art or music
  
• Watching another person complete a task, often in a diligent, attentive manner - examples would be filling out a form, writing a check, going through a purse or bag, inspecting an item closely, etc.
  
• Close, personal attention from another person
  
• Haircuts, or other touch from another on head or back "
