Scientists explain why scratching helps relieve an itch
Scratching helps to relieve an itch because it reduces the sensations of pain sent to the brain, a new study has found. However, the effect was produced only when the skin was genuinely itchy. Neuroscientists believe that the findings could be used to discover potential treatments, including drugs, to offer relief to patients suffering from chronic itches.

Dr Gil Yosipovitch, a dermatologist from Wake Forest University Baptist Medical Centre, North Carolina, found that scratching is linked to the suppression of unpleasant feelings.
In the study, the researchers used imaging technology to see what happens within the brain when we scratch, and why the sensation can feel pleasurable while it is damaging the skin.

FD: some how this does not satisfy my curiosity.
