Cold air can mask the intense sun's heat when you are hiking through high altitude passes, such as Kongmaru La or Bali Pass. At altitudes of between 4000 and 5500 meters exposure to sunlight is particularly dangerous, and could result in sunburn and other severe medical complications. We've seen that failing to recognize the dangers of sunlight can result in sunburns as well as more severe medical issues, including altitude sickness.
Why Is Sun Exposure Worse at High Altitude?
Thicker Atmosphere- More radiation is a result of lower UV filtering.
Reflection off snow & Ice: Up to 80 percent of UV rays can reflect off ice or snow and increase your UV exposure.
Cool temperatures cause burns Although you may not feel the heat directly on your skin, it's being removed from your body.
Dry Air and Wind: Exposure to dry air and wind can cause dryness of the skin cells as well as chapping.
