Anyone else get a cold sore the day after a long hike in the snow?

Did a big loop above the treeline on Saturday, bright sun, wind the whole way, and by Sunday night I had that tingle on my lower lip. I wore a hat and sunglasses but honestly forgot about my lips completely until it was too late. Is it the sun or the cold that does it, or just the combination of being wiped out afterwards? Curious how the rest of you handle winter days outside without it turning into a week of hiding my face.

Yes, every single time, and it took me years to connect it to the sun bouncing off the snow rather than just the cold. Now I keep my lips covered on those days and it happens way less, though honestly I still get caught out sometimes.

Yes, every single time, I can be careful all day with sunscreen everywhere else and then two days after a snowy hike my lip starts tingling like clockwork. The sun bouncing off the snow gets me way worse than a regular summer day for some reason.

Yes, every single time, and it took me years to connect it to the sun bouncing off the snow rather than the cold itself. Now I basically just accept that a long day out means the tingle is coming and try to be gentle with myself about it.

Yes, every single time, my lips get totally wrecked from the wind and glare off the snow and then I feel that tingle the next morning like clockwork. Now I basically live with balm in my pocket and reapply way more than feels reasonable, and honestly it's helped a lot.

Thank you for sharing. For most people the biggest lever is daily sun protection on the lips, even on cloudy days.

Yes, every single time, and it took me years to connect it. I always figured it was the cold but I think it's the sun bouncing off the snow onto my lips that does it, now I slather on the SPF before I even leave the car.
