Hi all,
which sun has highest concentration of UVB, but least concentration of UVA (skin cancer culprit).
Right now, I'm in equator area (Singapore) with only 2 seasons (just in case if geography has any effect local sun's UV ray distribution).
I've heard a lot of people saying that morning sun (between 6-9 AM is best), while noon sun (10AM - 3PM) only causes skin cancer. but lately, I've been hearing the opposite, it's the noon sun that's best for UVB, but need to beware of sunburn.
so, which one is right?
thanks
