Here in the Northern United States we have a cold, dry winter. Many people get chapped lips and dry skin during this season when the heating system is turned on and indoor humidity levels are very low. I have also heard that more sore nipples, probably due to even-too-small-to-see cracks, occur during this time. Less frequent bathing and a purified lanolin product do wonders.
