These techniques would be very useful in the three darkest months in Scandinavia, where the sun is down both when you leave and return from work, and generally behind clouds otherwise.
Me, I’ll climb the floors of the office and stand in a windowed stairwell with the sun in my eyes for ten minutes after lunch every day, when the weather’s good, but that’s being kind of anal about it.
The sarcastic self deprecating English in me wanted to say “well at least 4 days”, but we’ve had a pretty good run this year. We are up to at least 6 (lol, still can’t make myself say you are wrong..)
Where I live we have sun 18-22 hours a day in summer and maybe 4 hours in the winter - the sun doesn't even go halfway up before going down again on those days.
Unfortunately me and my partner both have our families here so moving is not an option. Being able to see decently strong light in December without having to travel would be worth a lot to me.
