Nicholas Namias, chief of trauma and acute care surgery at University of Miami’s Miller School of Medicine, said reaching for a stick of butter seems "intuitively obvious" because "it comes out of the refrigerator cold, so it certainly feels good."
"Anything that can cool a burn before the tissue has had a chance to 'cook' should lessen the severity of the burn," he said. "I advocate cooling small burns if it can be done immediately; I’ve seen burns that should have been worse do well seemingly because they were immediately cooled."
