This discussion on "seasonal depression", well, depressed me a bit. Out here in central Ohio, we miss out on a lot of the good aspects of winter. Temperature generally hover around freezing, no snow, no sun. Skiing in Ohio consists of man-made snow on a hill. Generally, it's just muddy and grey.
My wife gets especially grumpy at this time of year, so I looked into it with considerable attention.
We found that replacing the breakfast room light with a really bright full-spectrum fluorescent fixture really helped. I can also see how vitamin D might be beneficial.
However, I just ran across an article on using scents to help your mood.

I intend to try some of these scents, especially pine. We've had an artificial tree for many years and, aside from the pitch, the only thing I miss is the smell of a live tree.
