8 Common Misconceptions about Sunscreen: Keep You from Getting Darker

Fact: Ultraviolet rays do not generate heat. For example, when people climb mountains, the higher you go, the cooler the mountain wind becomes, yet at this time the ultraviolet rays are also stronger. For every 1000 meters you ascend, ultraviolet rays increase by 10%. The same principle applies on the open sea: the sea breeze makes you feel cool, but at such times the ultraviolet rays can reach an extremely intense level.
