  • Cold weather and wind
  • Hormonal shifts due to pregnancy or menstruation

Why Winter Weather Can Trigger Cold Sores

Winter is harsh to skin in general. Cold temperatures, low humidity, and strong winds are drying, and can make even healthy skin chapped. Chapped lips are more common in cold weather, and this can lead to minor breaks in the skin, particularly in the corners of the mouth. These breaks in the skin plus irritation due to cold and wind can lead to cold sore outbreaks. People who spend a lot of time outdoors during the winter, particularly participating in winter sports, are often exposed to more ultraviolet light than most people are during winter, and this can make an outbreak more likely too. Regularly using lip balm with sunscreen can help prevent outbreaks.

Most people find that they need to alter their skin care routines in the winter to effectively cope with drier indoor air, low humidity, and wind. People who do fine with soap and water during the warmer months may find that switching to a gentler cleanser like Cetaphil during the winter helps reduce drying and irritation. Likewise, people who may not need a moisturizer during warm weather may find that a gentle moisturizer applied regularly during the winter reduces skin irritation. Sun can be intense in the winter too, particularly on sunny days when there is snow cover. Use of sunscreen in the winter can block some of the ultraviolet rays that can trigger cold sore outbreaks.

  • Use your cold sore medication as soon as you notice symptoms like tingling, burning or redness.
  • Wash hands with soap and water before and after applying the medication, and make sure the area you’re treating is clean and dry.
  • Apply a thin layer of Denavir or other cold sore medication to completely cover the area of tingling, itchiness, redness, or sores. Apply the medication at intervals as directed by your doctor.
  • Cold sore medication works best when the levels absorbed by the skin remain near constant. That is why doctors recommend using it at regularly spaced intervals. You can set alarms on your phone to remind you when it’s time to reapply.
  • During outbreaks, avoid kissing and other close physical contact with others. Avoid touching the sores, and if you inadvertently touch them, wash your hands with soap and water afterwards.
