When it's cold outside, wearing warm socks, gloves and a hat should keep your feet, hands, and ears sufficiently warm. Some people have a condition called Raynaud's syndrome. This generally benign condition causes blood vessels in the fingers and toes to be overly constricted, making them feel very cold. The nose, lips and ears can also be affected. Raynaud's also causes temporary color changes. An affected finger may turn white or bluish and feel numb. It may turn red as it rewarms and throb or tingle.
