Not exactly 'help a burn heal'. Cold water, immediately applied will stop the burning process in its tracks. Right after a burn occurs, the flesh is still hot and damages the surrounding area, making the burn worse. Cold water stops this and in addition, temporarily relieves the pain. First aid = cold, clean water. not ice cold, not a forceful stream. Never ice, never butter, yes clean,dry bandage, yes get medical help quickly, if anything other than a very small burn not on a sensitive area, that is just a mild reddening of the skin.
