Most of people undergoes the condition states where the hairs stand on end or having piloerection when in fear. Fear is a feeling of an emotion that perceived by danger and also hazard that causing the change in a brain and organ function plus behaviour. [NILES].

[TORTORA]. The nerve impulses is sent by the thermoreceptors in the skin and also from the hypothalamus to the preoptic area, the heat – promoting centre in the hypothalamus and to the hypothalamic neurosecretory cells that produce the thyrotropin releasing hormone (TRH). [TORTORA]. Next, the TRH is secreted and stimulated the thyrotrophs in the anterior pituitary gland. This process will release the thyroid stimulating hormone. [TORTORA]. The release of epinephrine and norepinephrine into the blood by the stimulation of the adrenal medulla. This is the mechanisms from the nerve impulse in the sympathetic nerves. The cellular metabolism is surged when the hormone in turn is bring back and increase the heat production. [TORTORA].

A good thermoregulation response in cold environment is makes the hair stand on end. [HURON]. This will help in insulating the body from cold. Piloerection is produced by the aggression when the neural wiring is added. [HURON]. So, the present of chills will come together with the piloerection.
