Lumisal , to Ask Science in Regarding sleep quality, why did humans evolve to require full darkness?

I was wondering why it was so dark.

I used to live in. Jyväskylä. But the pictures and context you gave seem to be Uusimaa region.

I'm guessing the second one is dusk, assuming your camera didn't flip the image. Sun goes in a circle here.

The rolling blackout curtain from Ikea is what helps me a lot (I think the "fyture" one?)

Does this mean humans in far north climates have different methods of determinating sleep times? Because I'm originally from close to the equator and I'm the summer I'll be awake until near midnight when at least we get some dusk, but the nightless days really screw me up
