👉 Frost infection, also known as frostbite, is a condition that occurs when skin and underlying tissues freeze due to exposure to extreme cold. This can happen when body heat is insufficient to keep extremities like fingers, toes, ears, and the nose from freezing. The freezing process damages cells and blood vessels, leading to numbness, tingling, and eventually, tissue death if left untreated. Symptoms range from white or grayish-yellow skin that feels hard or waxy to complete loss of sensation and color. Frost infection can be categorized into three stages: frost nibbling (mild), frost cracking (moderate), and ice ball formation (severe), with the latter requiring immediate medical attention to prevent permanent damage or amputation. Preventive measures include dressing warmly in layers, avoiding prolonged exposure to cold, and recognizing early signs to seek prompt treatment.
