Why is sunburn worse at altitude?
Why is sunburn worse at altitude? At higher altitudes, the sun's rays have less ultraviolet (UV) light filtering atmosphere to blaze through, and the higher you climb, the thinner the atmosphere.
Where in the world is UV strongest?
Abstract. Chile's northern Atacama Desert has been pointed out as one of the places on earth where the world's highest surface ultraviolet (UV) may occur. This area is characterized by its high altitude, prevalent cloudless conditions and relatively low total ozone column.
What should you not do at high altitude?
Do not drink alcohol or do heavy exercise for at least the first 48 hours after you arrive at an elevation above 8,000 feet. Traveling to elevations greater than 9,000 ft for 2 nights or more, within 30 days before your trip, can help avoid altitude illness on a longer trip at a high elevation.
