Scratching

Scratching is a natural, instinctive behavior where an individual uses their nails or a tool to make repeated contact with their skin or surface, often to relieve itch, remove irritants, or mark territory. It involves a rhythmic, repetitive motion that stimulates nerve endings, temporarily calming discomfort and providing a sense of relief. While common, excessive scratching can damage the skin and lead to infections, so it's important to address underlying causes like allergies or skin conditions. Overall, scratching is a reflexive response to sensations on the skin, serving both protective and functional purposes.
