Goosebumps are an inherited physiological phenomenon. Goosebumps are tiny elevations of the skin that resemble the skin of poultry after the feathers have been plucked. The scientific name for goosebumps is piloerection. These bumps are caused by a contraction of miniature muscles that are attached to each hair, which causes a shallow depression on the skin surface and results in the surrounding area protruding. The contraction also causes the hair to stand up whenever the body feels cold or experiences strong emotions. In animals with a thick hair coat, this rising of hair expands the layer of air that serves as insulation. The thicker the hair, the more heat that is retained. In people, this reaction is useless because we lack a thick hair coat, but goosebumps persist nevertheless. Getting goosebumps could boost hair growth. In a new study, a Harvard scientist reported that getting goosebumps not only makes the hair stand up, but it also helps hair grow.

Nerves and muscles that raise goosebumps also stimulate cells in the skin to make hair follicles and grow hair. Nerves that are a part of the nervous system -- which controls pupil dilation, pulse and other automatic processes-- settle alongside hair follicle cells. also secrete a hormone, called norepinephrine, that is responsible for hair growth. Sympathetic nerves and arrector pili muscles, may also be important in that type of baldness. Restoring the may lead to new hair growth.

Nerves and muscles that raise goosebumps also stimulate dermal cells in the skin to make hair follicles and grow hair. Nerves that are a part of the autonomic nervous system -- which controls pupil dilation, pulse, and other automatic processes -- settle alongside hair follicle cells. These nerves also secrete a hormone, called norepinephrine, that is responsible for hair growth. Sympathetic nerves and arrector pili muscles may also be important in that type of baldness. Restoring the function of these nerves or muscles may lead to new hair growth.
