My old roommate had a full spectrum light he kept in his desk. We don't get much sun, so it was to help compensate (for stuff like mental health and such)
In most of Canada, winter days are short enough that many people get to the office before the sun is fully up, and leave work after it sets. Seasonal depression is a very real thing.
It's funny how people are. I don't think I can cope with the weather being hot all the time. Cold is fine, I can deal with that, but hot, ugh.
Where I live we don't really have any mechanism to lose heat. Other than open a window but then every insect on the planet comes inside. But I can just turn up my heating if I need warmth.
Plus of course because I know it's cold here so I have cold weather clothing, I don't really have hot weather clothing. So when it is hot I still have to wear cold weather clothing just less off it.
