For example, did you know that as temperatures drop and cold-weather-related illnesses rise, the chance of a cold sore being triggered increases? Cold temperatures and illness are just two triggers that can cause cold sore outbreaks. Other triggers include stress, sun exposure, injury to the mouth, and lack of sleep. Stress, which tends to rear its head during the winter months as many people prepare for the holidays, coupled with cold weather can create the perfect storm for a cold sore outbreak as we enter cold and flu season.
