UV index and sunscreen

Hi! I was wondering if it's ok to go without sunscreen when the UV index is below 3. The WHO seems to think so (http://www.who.int/uv/intersunprogramme/activities/uv_index/en/index1.html), but I found people in forums who say that this index only measures UVB, so you should wear sunscreen anyway. I'm really confused about UVA, a lot of sites say different things about if the rays are equally strong all year round at all hours.


  • It's best not to over think this: When you're out in the sun you should wear sunscreen (or protective clothing) if you want to protect your skin.
