Agreed, considering "EEA" to mean the African savannah. So for instance if your ancestry is European and you're currently living in California you don't need to spend very much time outside, and if you're dark-skinned and living at a high latitude you should try to get lots of sunlight.

Evolutionary selection pressures are strong enough that skin color of natives over the world corresponds to the level of sun exposure of various places.

Of course being indoors means that you get less sun then the environment for which evolution prepared you.
