What triggers cold sores? Sharing my trigger list

After tracking for a year my cold sore triggers are clear: UV and sun on the lips, stress, poor sleep, illness, and cold windy weather that cracks my lips. What are your main cold sore triggers?

Stress and deadlines set mine off every time.

UV is my number one trigger by a mile.

Cold wind and chapped lips are my winter trigger.
