Does Cold Weather Help Creativity?

With yet another extremely cold week ahead of me, the last thing I want to do is leave the house. That means lots more time spent cooking elaborate meals, catching up on my reading list, and dedicating time to improving my Japanese language skills. Unfortunately my writing hasn't been getting too much attention lately, but if the cold spell continues, I might just revive one or two projects to fill in the long evenings.

As always I spend as much time in a day as I possibly can on editing and proofreading work. It just got me to thinking that I spend a lot more time working on constructive projects when it is cold outside. Is it just me?
