Which depth of burn is not treated with water?

Third-degree burns, also known as full thickness burns, are not treated with water because they cause extensive damage to the skin, including the epidermis and dermis, potentially affecting underlying tissues. The skin may appear charred, leathery, or white, and there is a loss of sensation in the affected area due to nerve damage. Pouring water on these burns can exacerbate injury, increase the risk of infection, and may lead to additional complications like hypothermia or severe pain due to nerve exposure.

In contrast, first-degree burns, which only affect the outer layer of skin (epidermis), and second-degree burns, which impact both the epidermis and part of the dermis, can generally be treated with cool water to alleviate pain and reduce swelling. Electrical burns are also distinct as they can cause internal damage and may require specific medical interventions, but initial treatment often does not involve soaking in water. Hence, while other burn types might benefit from water application, third-degree burns require specialized medical treatment rather than water.
