Can stress cause cold sores to form?

A cold sore breakout can be triggered by a number of factors, including stress1. Some of the most common stressors people deal with on a regular basis include job interviews, major life events (such as weddings), work deadlines, exams, financial troubles, fatigue, and lack of sleep. Unfortunately, though, it is unknown exactly how or why increased stress may cause a cold sore to form.

Other cold sore triggers include:

  • A viral infection1
  • Wind exposure1
  • Sunlight exposure1
  • Hormonal changes1
  • Changes in immune system1
