Frostbite occurs when so much heat is lost that water in tissue close to the skin freezes. The ears, face, fingers, and toes are most susceptible. Early signs include tissue that is waxy, white, numb, tingly, and cold. The earliest signs include numbness in the hands and feet and slight shivering. Continued exposure to the cold can lead to more intense shivering, slurred speech, drowsiness, even a feeling of exhaustion.
Serious cases require immediate medical attention.
Problem prevention Activity in cold weather can be safe and enjoyable if proper precautions are taken. Layers of loose-fitting clothing trap air and provide good insulation. Top things off. Keep the hands, feet, and head warm. Wear mitts or gloves, warm socks, a hat, and even a face mask on very cold days.
