Scratching is a common behavior in many animals, including humans, where the skin is rubbed or scraped with a fingernail or object. This action often occurs in response to an itch, which can be caused by various factors such as insect bites, allergies, or dry skin. Scratching can provide temporary relief from discomfort but may also lead to skin irritation or infection if done excessively. In addition to its physical effects, scratching can also have psychological aspects. For instance, it can serve as a coping mechanism for stress or anxiety. In some cases, individuals may develop a habit of scratching, leading to conditions like dermatitis or eczema, which require medical attention to manage effectively.
