Why Does It Feel Good To Scratch An Itch?

Thu Mar 30, 2006 12:41 am

Simple question really.


Is there a simple answer?

Yes. You stimulate tactile receptors in the skin which in turn override the "itching" sensation neurons in the spinal cord, promoting relief of the "bad" sensation and informing the body that the possible injury (perceived as an itch) has been removed.

That is the same principle applied when you decrease the pain from an injury by rubbing it.

how come when you scratch a mosquito bite or a rash it itches even more?

Probably because it irritates the bite, or spreads the rash around. Just my guess, perhaps somebody can confirm or correct me.

Only if you're secretly Scottish.

Sure, we're concerned for our lives. Just not as concerned as saving 9 bucks on a roundtrip to Ft. Myers.

Because it relieves you. Like picking your nose or having a good shit.

Scratching is the natural reaction to itching and it generally provides instant relief, but not necessarily long-lasting relief. Very often the itch will go away with or without any scratching. Your nose itches, or your scalp, or your foot. For many everyday itches, a little scratch is just what is called for. Scratching excites the pain neurons and masks the itching sensation.

Regardless of the cause of your itching, a little scratch might solve the problem. If that doesn't work, you might try a cool compress, a moisturizer, or over-the-counter hydrocortisone creams or antihistamines. (Be sure you read all labels carefully and follow directions.)
