Sunscreen / sun protection
Sunburn is a major cause of distress to travelers and can have long-term effects. Chance of sunburn is increased around water, when the light is ‘reflected’ from a swimming pool, lake, or the ocean. This also applies to white sand and snow.
While the use of sunscreen is often misunderstood and over-stated, we recommend using it in combination with sun protection clothing (yes, even in the heat, as exposed skin makes you even hotter). We also recommend you wear 100% UV glasses, polarized if possible.
More and more outdoor clothing now carries a UPF rating. What does this rating mean? Why should you care about sun protection clothing?
