Thermal burns are injuries caused by exposure to high temperatures, such as flames, hot liquids, or steam. These burns can damage the skin and underlying tissues, leading to pain, swelling, and redness. The severity of a thermal burn is classified into three degrees: first-degree burns affect only the outer layer of skin, second-degree burns involve deeper layers, and third-degree burns can damage all layers of skin and underlying tissues. Treatment for thermal burns depends on their severity. First-degree burns can often be treated at home with cool water and over-the-counter pain relief. More severe burns may require medical attention, including bandages, antibiotics, or even surgery to promote healing and prevent infection.
