The first and most important step in treating a burn is to stop the burning process immediately. This may involve removing the source of the burn, like removing clothing or jewelry near the burn area. After that, cool the burn with cool or lukewarm running water for at least 20 minutes. This will help to reduce pain and inflammation. Never use ice, iced water, or any creams or greasy substances like butter. Once the burn is cooled, you can remove any constricting clothing or jewelry. Keep yourself or the person warm as they may feel cold after the burn is cooled.
For minor burns, you can apply a thin layer of lotion to help keep the area moist and prevent infection.
For severe burns, it is important to seek immediate medical attention.
