Parts which have been frozen should not be thawed too quickly, as more harm will be done by the rapid thawing than by the freezing. If a person has been exposed to the cold so long that considerable portions of the body are frozen, he should be carefully kept away from the fire or a very warm room, being first brought into a room of quite low temperature, where the frozen parts should be rubbed with melted snow, or very cold water, until they become pliable. The temperature of the room should be gradually raised, as the parts are thawed. Sometimes it is necessary to continue rubbing for several hours before the interrupted circulation is restored. After this has been accomplished, the parts should be anointed with sweet oil or vaseline. By this course, much of the injury which generally results from freezing may be avoided.

If ulceration takes place, the sore should be treated as directed for burns.

If a person finds himself in danger of freezing, through exposure in the open country in very cold weather, he should resolutely resist the drowsiness which will come over him and keep moving until the last. If a piercing wind is blowing, he should take shelter in some hollow in which there may be an accumulation of snow. The snow itself is not a bad protector from the cold, so that a person would be much safer if buried in a snow-bank than when exposed to the wind.
