Really? The no-sun condition would drive me insane.

Some parts of the world can go without sunlight for months on end (and constant daylight at the opposite time of year).

Personally I’ve gone a week without sunlight and rather enjoyed it.

You mean the parts of the world where seasonal affective disorders are a blight on their society?

Personally I severely underestimated the effect of large periods of time without sunlight, before going through it myself

I don’t really understand why people have taken such an objection to my comment. It’s factually accurate.

I’m not suggesting that SAD isn’t a real thing either. Clearly there’s even a lot of research into it. In fact I have a few friends who suffer from it. But SAD was never my point.

the point behind my point was just stating that plenty of people do live without the sun for extended periods and thus this article isn’t an isolated incident.

And literally the only reason I made such a point was because the GP seemed surprised that someone might live that way.

I'm not insignificantly of Scandi descent on both sides of my family, so I dare say that accounts for something in terms of feelings towards light. There's Cypriot, Sudanese and Ashkenazi Jewish too, but heavily Scandi.

I do enjoy sunlight, but a lack of it isn't the end of the world for me. The world keeps on spinning, I don't become dysfunctional from a lack of light, though my mood is elevated by it like anybody.

Thinking about it for a few hours, yes, I would happily go and live in a cave for a few years. Wouldn't want to spend my entire life there as I feel I'd miss out, but yes, wouldn't bother me much. I'm very comfortable with being on my own.

It affects some people, but not all.

I suspect this is something that researchers would be interested in regarding the person in this article as well, given their statements.

It's probably because I associate it with being outside. Specially in the summer it feels so good, also the odors of the woods and fields, the green and yellow colors. To me the winter is super depressing, even though I go out every day for at least an hour. The colors are dead, the sun rarely shines, so for me the sun is what gives all my senses so much to enjoy, also because of what it does to the environment.

But regarding those communities which do have extended periods of missing sunlight, they do have bars and other places where they meet and feel some warmth, and will always have the thought of this state being over in a couple of months. I guess they mostly do it because the nature imposes it on them.
