The increased sunlight seems like a possibility. I wonder what would happen if you used a light box during winter. Not that you want to bring on insomnia, but it might give you more data.
It could also be the changes in atmospheric pressure--do you notice any change with rain vs. sun?
And just because it's what I think when people notice spring symptoms, I wonder if there's some way that it's allergies. Or, now that I think of it, hormone fluctuation.
