[sun care] Are you safe from UV rays in the shade?

Beauty Tips For Body Care
Is it excessive to worry about UV rays in the shade? Some people say "if you see light, there's UV" but this is near impossible to protect against.Example 1, it's a bright summer day and you're completely shaded by a tree.2.) It's sunny and summer and you're sitting at a desk away from direct window light.3.) It's summer but you avoided the sun enough to not even tan. If you don't tan during summer at all, can you really get sun damage being that careful?Are any of these situations enough to wear sunscreen or is the UV exposure too low?
