Why Cold Sores Are More Common in Winter

Cold sores (herpes labialis) are more common in winter—and there are a few clear reasons why, plus practical ways to prevent flare-ups.

Why winter triggers cold sores

Cold, dry air	Low humidity dries and cracks lips, weakening the skin barrier and making it easier for HSV-1 to reactivate.
Weakened immunity	Winter illnesses, less sunlight (lower vitamin D), stress, and fatigue can reduce immune defenses.
Wind & temperature swings	Repeated exposure to cold wind outdoors and dry heated air indoors irritates lips.
Lip licking & dehydration	Chapped lips lead to more licking—this worsens dryness and micro-cracks.

Early warning signs

• Tingling, itching, or burning on the lip or lip border

• Tightness or sensitivity before a blister appears

  
  

  ➡️ Act immediately—early care can shorten duration.

Winter prevention tips

Seal	Use a cold sore patch with SPF protection to provide a protective barrier.
Hands off	Avoid touching or picking at lips.
Support immunity	Prioritize sleep, manage stress, stay hydrated; consider vitamin D if you’re low.
Sun still matters	Snow reflects UV—use an SPF lip balm on bright days.
Avoid irritants	Skip fragranced or minty products during an outbreak.
