Burns

Burns are injuries to the skin and underlying tissues caused by heat, chemicals, electricity, or radiation. They are classified by severity: first-degree burns affect only the outer layer of skin, causing redness and pain; second-degree burns involve deeper skin layers, leading to blistering and swelling; third-degree burns destroy all skin layers and may reach nerves, causing numbness. Burns can result from accidents like fires, scalds, or contact with hot objects. Treatment varies based on severity, ranging from cooling and pain relief to advanced medical interventions like skin grafts. Prompt care is essential to prevent complications and promote healing.
