There is a wide variety of circadian rhythms, yours is just one of the most common, but it does not make it any more "natural" than the others. Some of us are night hunters, and no sunset can give us a sufficient kick.
I rather suspect it's staying up past sunset that's "unnatural", rather than waking around sunrise.
