Mountain getaways are magical—fresh air, sweeping landscapes, and starry skies. But what many travelers forget is that high-altitude regions come with an invisible danger: stronger ultraviolet (UV) radiation.
Why UV is Stronger in the Mountains
At higher altitudes, the air is thinner and absorbs less UV radiation. On average, UV intensity increases by about 10–12% for every 1,000 meters above sea level. Combine this with reflective surfaces like snow, ice, or even bright stone, and the exposure multiplies.
Other factors also make a difference:
-
Latitude – The closer to the equator, the stronger the baseline UV.
-
Ozone layer thickness – Thinner ozone means less natural filtering.
-
Air clarity – Fewer clouds and lower pollution at higher altitudes let more UV pass through.
Where UV Exposure Hits Hardest
-
Andes (Peru & Bolivia): A double challenge of extreme altitude and equatorial positioning.
-
Tibet & Himalayas: Some of the world’s highest human settlements, with little atmospheric shielding.
-
Swiss Alps: Strong UV from elevation, especially on reflective snowy peaks.
Rocky Mountains, USA: Noticeably higher UV than lowlands, though less extreme than equatorial ranges.
-
Lijiang & Shangri-La, Yunnan, China: At the gateway to the Tibetan Plateau, these beautiful destinations sit thousands of meters above sea level, where the sun feels deceptively gentle but UV is fierce.
How to Protect & Recover from UV Burns
1. Apply Sunscreen Correctly
Choose a high SPF (50+ recommended) sunscreen. Spray types are more breathable and comfortable for long hours outdoors. Reapply every two hours—or more often if you’re sweating or exposed to water.
2. Moisturize Generously
UV dries out skin quickly. Carry body lotion and hand cream to restore moisture. Aloe vera gels and lightweight lotions are soothing options after a long day.
3. Wear Smart Protection
Bring a wide-brim hat, UV sleeves, polarized sunglasses, and long clothing. These provide a physical shield that sunscreen alone can’t match.
4. Soothe Your Skin at Night
Back at your hotel, apply cooling sheet masks to the face. If your hands and legs are also exposed, pamper them with hand and leg masks—available in many Asian beauty shops.
5. Mist Frequently
Hydration mists are a traveler’s best friend. Keep one in your daypack to refresh your skin indoors and outdoors.
Two More Things Travelers Must Know
6. Don’t Forget Your Eyes
At high altitudes, UV rays are equally harsh on the eyes. Snow, ice, and water can reflect UV and cause photokeratitis (sunburn of the cornea). Always wear sunglasses with full UV protection, preferably wraparound styles that block rays from the sides.
7. Hydrate from Within
External care isn’t enough. High elevations can dehydrate the body faster due to dry air and increased breathing rate. Drink more water than you normally would. Add electrolytes or coconut water for balance, especially if you’re hiking. Well-hydrated skin recovers faster from sunburn.
Eye Care in the Mountains
When traveling to high-altitude destinations, most people think about skin protection but forget their eyes—yet UV damage can be just as serious here.
Sunglasses with Full UV Protection
Invest in quality sunglasses that block 100% of UVA and UVB rays. Wraparound styles are best, as they reduce UV entering from the sides. If you’re in snowy or icy areas, polarized lenses can cut glare and make it easier to see.
Use Hydrating Eye Drops
Thin, dry mountain air can leave eyes feeling irritated, red, or gritty. If you already have dry eyes, this can worsen quickly. Carry lubricating eye drops and use them regularly throughout the day to keep your eyes hydrated and refreshed.
Rest Your Eyes
Strong sunlight and long hours outdoors can strain the eyes. When possible, take short breaks indoors or in shaded areas to let your eyes recover. This is especially helpful if you’re also adjusting to the higher altitude.
