Neutrophils and monocytes with pyrogen in precursors, to a certain stimulus conditions, white blood cells can be activated, and release the pyrogen. Pyrogen by blood flow to the hypothalamus thermoregulatory center, Central after stimulation of thermoregulation, would produce exciting, the impulse through the capillaries of the skin caused by sympathetic contraction, reduced blood flow, then skin temperature will decrease, thus stimulating increased skeletal muscle tension caused by temperature sensors, micro-shrinkage of muscle fiber, furring in the skin muscle contraction. Therefore, appears in children with shivering, we will see the child\'s skin appear \"goose bumps\".
