Why the hell are you waking up so early then? The last time I intentionally woke up before sunrise was years ago at 4:30am at the bottom of the Grand Canyon to start the hike back up before it got too hot.
People in those latitudes are just screwed either way then. There's literally not enough daylight to go around in winter. If you're not waking up in the dark then the Sun is setting when you're only halfway through your work day.
