- What Causes "Goose Bumps"?
-
-
- ------------------------------------------------------------------------------
-
- QUESTION: Whenever there is a bit of an extra chill in the air, and whenever
- I am startled or emotional, my skin breaks out in a crop of "goose bumps". I
- know it is not harmful, but I can't help wondering what it means. Can you
- please tell me just what causes these peculiar bumps?
-

- ANSWER: It's all part of some left over reactions we inherited from our
- primitive ancestors. Thinking about some of our pets, whose hair stands on
- end when they are frightened, will help you understand your own situation.
- Each of our hairs are supplied with a tiny muscle. Its called the "arrectoris
- pili" muscle (and means it causes the hair to stand erect). In some areas of
- our skin the muscle, which is part of the hair follicle, is still present
- although the skin is hairless. When we are frightened or aroused, in fact
- anything that stimulates the production of adrenaline in our system, these
- muscles contract. If there is hair present, it "stands up". In hairless
- skin, it produces "goosebumps", or "gooseflesh" if you will. It's an
- interesting reaction, but can give your thoughts away if you become emotional
- over someone who is a careful observer.
