Scratching an itch provides temporary relief by creating a mild pain sensation that distracts the brain from the itch signal. This activates pain receptors and can inhibit the itch signals being sent to the brain. Additionally, scratching stimulates the release of serotonin, which can further reduce the sensation of itching. However, it can also lead to skin irritation or damage, potentially worsening the itch in the long run.
