7. Wind Exposure
If the lips get too dry and cracked, it is possible for cold sores to develop. Licking the lips can increase susceptibility to an outbreak and even cause the virus to spread around the mouth. High wind can quickly dry out the lips and cause them to get cracked.
People are more likely to develop cold sores in the winter. The transition from cold, windy weather to a warm, heated indoor environment can be especially traumatic on the skin around the lips. Using lip balm regularly and covering the mouth with a scarf or jacket can help with prevention.
