This document discusses different degrees of burns and their treatment. A first-degree burn only affects the outer layer of skin, causing dryness, pain and sensitivity. A second-degree burn involves deeper layers of skin and causes swelling and blistering. A third-degree burn is the most severe, affecting all skin layers and potentially underlying tissue. It causes dry, discolored skin that may break open. More serious burns can impact muscles and bones. The document provides guidance on treating different burn degrees, such as cooling with water and seeking immediate medical help for severe burns.
