I moved from Seattle to Austin and I no longer had seasonal affective disorder in the fall and winter. However, I did get a little depressed in August, because that's when you realize that summer began 4 months ago, and there's still 2.5 months of 100 degree days to go. Depending on how far north you are and how cloudy, going outside in nature might be beneficial. For me I find that being in a city when it's dark is super depressing, but if I give my body some contextual clues -- the look and smell of autumn leaves, eating autumn food, etc. -- it can help. Then my brain puts the darkness into "circle of life" category a bit more instead of "the light is fading and with it comes death!" That said, I think that would not work for me in Seattle. It's too dark and too overcast. But has worked for me a bit better in southern New England.
