Frostbite can happen in temperatures at or below 0°C, often affecting fingers, toes, ears, nose, and chin. Early signs include color changes, coldness followed by numbness, and irritation. If blisters form or skin turns hard or black, treat it as severe. Move to a warm place, remove wet clothing, and gently warm the area in warm water (no more than 42°C). Do not rub. Seek medical care promptly.
