This article is about the physiological symptom. For other uses, see Chill (disambiguation).

Chills is a feeling of coldness occurring during a high fever. It occurs during fever due to the release of cytokines and prostaglandins as part of the inflammatory response, which increases the set point for body temperature in the hypothalamus. The increased set point causes the body temperature to rise (pyrexia), but also makes the patient feel cold or chills until the new set point is reached. Shivering also occurs along with chills because the patient's body produces heat during muscle contraction in a physiological attempt to increase body temperature to the new set point.

Causes[edit]

Chills are commonly caused by inflammatory diseases.
