Cold air does not tell you how much ultraviolet radiation reaches your skin and eyes. The winter UV Index may often be low at home, but the situation changes on a bright day beside snow, high in the mountains or after flying south. The useful approach is not to copy a summer routine automatically, but to check the UV Index and the conditions where you actually are.
When should you take extra care?
- skiing or walking at altitude;
- spending a long time in a bright, snow-covered place;
- travelling to a sunnier climate;
- staying outside for many hours when the UV Index indicates protection;
- using medicines or skincare that may increase sun sensitivity—in that case, ask an appropriate professional.
Why does snow matter?
Fresh snow can reflect a substantial amount of UV radiation, so exposure does not only come from above. Altitude adds another consideration in the mountains. Your face and eyes may receive more UV than the cold temperature suggests.
A precise percentage is not needed for everyday planning because reflection varies with snow and surroundings. The practical point is to check the UV Index and protect the face and eyes around bright snow.
Eyes and face
For skiing, choose activity-specific eyewear with suitable UV protection. For ordinary outdoor time, use sunglasses with clearly stated UVA and UVB protection. Apply reliable broad-spectrum sunscreen to the face and other exposed skin according to its directions.
Clothing layers
In winter, clothing first needs to manage warmth, wind and moisture. Layer for the activity: a moisture-managing base, insulating middle and weather-resistant outer layer. A UPF long sleeve may be an additional travel or southern-sun layer, but it is not a replacement for a ski base layer or windproof jacket.

A winter trip south
When leaving Lithuania or another northern country, it is easy to pack for the weather at home. Check the destination’s UV forecast and bring a hat, sunglasses, sunscreen and a light covering layer. Avoid turning the first day into a full day in strong sun simply because you have missed it.
Five winter checks
- Check the UV Index at your destination.
- Protect eyes and face around snow.
- Use technical clothing appropriate to mountain activity.
- Pack a light covering layer for southern travel.
- Apply sunscreen to exposed skin as directed.
Winter sun protection is not about treating every cold day like midsummer. It is about responding to the actual conditions in front of you.
