  1. Rub them with snow so they warm up slowly
  2. Hold them close to the campfire or a heater
  3. Soak them in warm, not hot, water and don't rub them ✔

Why: Rubbing, even with snow, hurts frozen skin more. Numb fingers can't feel heat, so a fire or heater can burn them without anyone noticing. Soak them in warm water for about 30 minutes, and get help from a doctor.

Huh, didn't know that: Soak them in warm water for about 30 minutes, and get help from a doctor.
