Arctic
- Don't massage frostbite and try not to thaw it out unless you can be sure you can keep it thawed. Refreezing damaged tissue can be extremely dangerous and cause even more damage.
- If left untreated, frostbite will cause the skin to turn white and may eventually lead to blistering and even become black if it turns gangrenous.
- If unable to get medical attention try to keep the frostbitten area warm and dry. Wrap it in sterile dressing if available.
- If feet are frostbitten don't try walking on them, this can extenuate the damage to the frostbitten tissue. Instead send out for help if possible.
- To thaw part of the body affected by frostbite, immerse it in warm, not hot, water for about 30 minutes, circulating the water to aid the warming process.
