The point is the sunrise clock works differently than a vibrating clock or noise clock. The sunrise clock brings you out of a deep sleep, as nature would do. So you actually wake up, gently, before the sound alarm (birds chirping) goes off. You were not woken from a deep sleep so you aren't groggy.
