It's hard to say. I was doing a lot of hiking and outdoor activity last summer, and it didn't really make that much difference (if anything, being in better shape gave me more energy at the end of the day). I do find I have an energy slump in the early evening and wonder if there is some way to take advantage of that, but haven't been able to push myself to try a sleep schedule change that drastic (and my hunch is that it'd just push that slump earlier and I'd start drifting again, just starting from an earlier point in the evening).
