Why Do You Get Goosebumps?
Goosebumps are a physiological phenomenon inherited from our animal ancestors, which was useful to them but are not of much help to us. Goosebumps are tiny elevations of the skin that resemble the skin of poultry after the feathers have been plucked. (Therefore we could as well call them "turkeybumps" or "duckbumps.") These bumps are caused by a contraction of miniature muscles that are attached to each hair. Each contracting muscle creates a shallow depression on the skin surface, which causes the surrounding area to protrude. The contraction also causes the hair to stand up whenever the body feels cold. In animals with a thick hair coat this rising of hair expands the layer of air that serves as insulation. The thicker the hair layer, the more heat is retained. In people this reaction is useless because we do not have a hair coat, but goosebumps persist nevertheless.
Chilling Out
While cold goosebumps are pretty universal, Colver says not everyone what experiences skin orgasms. It’s estimated that between 55 and 80 percent of people do, with some more prone to experiencing the phenomenon than others.
