Sunlight in your eyes that early isn't very easy during winter months when the sun may not come up till 8 or later.

However I can confirm that sunlight in the eyes is a great way to stay awake during long road trips (ie sunglasses can make me drowsy).

Even now. I've been awake since 5, it's now 9 am and we're just getting to the point where I would consider it day time. And that's 3 months away from the darkest day of the year. Changing to standard time changes a bit for a bit, but up here in Canada we go to work and come home in the dark.
