I recently went on a trip with my parents and majority of the trip involved walking around in national parks or sites with little shades available, I was wearing a cap and used sunscreen, whereas my parents opted to use umbrellas. I think it's not uncommon to use umbrellas as protection from the sun in Asia, but it seems that not a lot of people are doing that here.
It prompted me to think that being in a country where we are prone to sun damage and at high risk of skin cancer, why wouldn't people use umbrellas on extremely sunny days, surely physical barriers would be a lot more effective than sunscreens which might not be applied property and they lose their effectiveness over time/being in water etc. The only down side I can think of is if you are in an area with a lot of people, it can be a bit annoying to walk around trying not to block other's way.
I'm talking about protection from sun when you have to walk for a longer time, for health reasons, not when you have to walk down to the shops for 5 minutes or obsession of having pale skin.
What do you guys think?
