Kuumakahjustus, commonly referred to as a burn, is damage to the skin or other tissues caused by heat, friction, electricity, radiation, or chemicals. The severity of a burn is classified by its depth and the extent of the affected area.

First-degree burns affect only the epidermis, the outermost layer of skin. They typically cause redness, pain, and mild swelling, but no blisters. Sunburn is a common example.

Second-degree burns involve the epidermis and part of the dermis, the layer beneath the epidermis. These burns are characterized by redness, pain, blistering, and swelling. They can be superficial or deep partial-thickness burns, depending on how much of the dermis is affected.

Third-degree burns penetrate the full thickness of the skin, damaging the epidermis, dermis, and subcutaneous tissue. The affected area may appear white, leathery, or charred, and there may be little to no pain due to nerve damage.

Fourth-degree burns extend even deeper, affecting muscle and bone. These are severe injuries that require immediate medical attention.

Treatment for burns depends on their severity. Minor burns can often be treated at home with cool water compresses and over-the-counter pain relievers. More severe burns require professional medical care, which may include wound cleaning, debridement, grafting, and pain management. Prevention of burns involves taking precautions such as being careful with hot liquids and appliances, using sunscreen, and following safety guidelines when working with electricity or chemicals.
