Cold chill

A cold chill (also known as chills, the chills or simply thrills) is described by David Huron^{[clarification needed]} as, "a pleasant tingling feeling, associated with the flexing of hair follicles resulting in goose bumps (technically called piloerection), accompanied by a cold sensation, and sometimes producing a shudder or shiver." Cold chills are a purely subjective response and, unlike piloerection, no objective physiological measure of cold chills exists. Unlike shivering, however, it is not caused by temperature, but rather is an emotionally triggered response^[1] when one is deeply affected by things such as music,^[2][3] speech, or recollection. It is similar to autonomous sensory meridian response; both sensations consist of a pleasant tingling feeling that affects the skin on the back of the neck and spine.^{[citation needed]}

Goose bumps

However, cold chills should not be confused with piloerection. Recent research has shown that self-reported chills do not correspond with observable piloerection,^[4] suggesting that they are independent phenomena.
