I’m Swiss, but I was born and raised in the Gulf states. When I visit Switzerland during the cold season, I immediately become depressed, irritable, and in a bad mood. I prefer the heat 100%. I don’t think I could live in a place with a cold climate and be happy.
Fall is probably my favorite season, followed closely by winter. I do use full-spectrum lights to compensate for the shorter days, but overall I think my mood is better during that time. Winter in a forest is one of the most beautiful things in the world.
