"Many people think that after getting frostbite, they can warm up by sitting near a fire. In movies and TV shows, you often see rescuers rubbing snow on the body of someone with frostbite. But these methods are all wrong."
"When frostbite is severe, you can't rub it with snow, vigorously massage it with a towel, or warm it by fire—doing so will cause the wounds to fester, part of the tissues to get damaged, and they will be difficult to heal."
"To treat frostbite, you first have to get out of the cold environment as quickly as possible and then immerse the person in water that is between 40 to 42 degrees Celsius, making sure to keep adding water to maintain the temperature during the soak."
"I don't have those conditions here, so I can only use frostbite ointment for rubbing and rewarming. If that weren't available, oil would also work; both are smooth enough not to cause secondary injury from rough rubbing."
