your body hormones are secreted in Circadian rhythm . means there is fluctuation in the secretions during thr 24 hours . Highest concentration of body hormones will be in the early morning of each day . if you spend this period sleeping surely there will be disturbance in your body functions . also some hormones are belived to be secreted intensely at night during sleep . staying up late will make disturbance in their functions .
Also dont ignore the psychological aspect . if wake up late after time you might get depressed . you are supposed to wake up early to see the day light and the sun rising in the sky . gives you some hope in a brand new day . i am not a poet . this is true .

Our eyesight isn't that great in the dark. Creatures living in trees (i.e. the apes from which we are descended) don't want to be moving around when they can't see what they are doing - too easy to run into predators or fall off a branch.
