"If your fingers, toes, or face start freezing on a cold trail, rubbing packed snow over the affected area will friction-heat the tissue and safely restore blood flow."

Written By Uncle Jon

• • The Myth: Friction from rubbing snow on cold or frostbitten skin safely warms the tissue and reverses freezing.

  • The Fact: Frostbitten tissue is filled with micro-ice crystals that freeze and expand inside skin cells, making the tissue extremely fragile. Rubbing snow or applying hard friction acts like dragging sandpaper across glass—it crushes the microscopic ice crystals directly into the delicate cells, causing severe, permanent tissue damage and increasing infection risks.

• The Breakdown: Treating frostbite with snow is a dangerous folk remedy that turns manageable frostnip into irreversible cell death. Ice crystals in the snow add further freezing temperature to already compromised skin, while the physical rubbing tears frozen blood vessels underneath.

• What You Should Do Instead: Get out of the cold immediately. Warm the affected area gradually using body heat (like tucking cold fingers into an armpit) or soak it in warm—never hot—water (around 100°F to 104°F). Avoid direct heat sources like fires or heating pads, as numb skin cannot gauge temperature and burns easily.
