- What is an Itch and Why Does Scratching Make it Go Away?
-
-
- ------------------------------------------------------------------------------
-
- QUESTION: I found myself scratching away at an annoying, but not too serious
- itch, that sprang out of nowhere. I didn't want to damage the skin, so I
- decided not to give in to my instinct. I could not help myself. Then I
- noticed my dog scratching away at his itch. So I began to wonder, what is an
- itch? Where does it come from, and why does scratching make it go away? It
- sounded interesting enough to submit it to you for an answer. An itch is a
- strange thing.

- ANSWER: It may seem strange, but to people who suffer intense itching, it
- certainly isn't funny. Actually an itch is a little pain. It comes when a
- nerve that can carry pain is only slightly stimulated. The itch results from
- something stimulating the outer layers of our skin, while pain usually results
- when the deeper layers of skin are affected. And an itch can be caused by
- psychological factors. You may scratch when you see someone else doing it, or
- when you think about little things crawling over your skin. (There you go, I
- caught you scratching!) When you do scratch you set up a more intense
- stimulation to the nerves, which over rides the sensation of itching and makes
- you feel better. And you are right. If you scratch too long or hard, you can
- damage the skin, opening scratches that can result in infections. While the
- act of scratching may seem instinctive, it probably is a learned behavior.
- When we scratch it feels better, and so we repeat the gesture at the next
- "itchy" impulse.
