why do i not see to wake up natrually no matter how early i got to bed ?

while waking up from 23:00 will be less jarring than waking from 24:00 in time of 6:30, i might need to push it to 8:20 - 2:00 = 21:00. what 21:00, i do not sleep in that time anymore.

yesterday last sleep (4.9.2024) i had a headache from the last sleep but i fell to deep sleep fairly easily for sleeping standards and i did not wake up at random time like 3 amor 1 am.

getting sunlight is pointless because at 6:30, there is not sunlight trough window, its just dark.
