If you fall asleep at 8pm and wake up at 4am with 8 hours of sleep why do you feel extremely tired by 10am, but if you go to sleep at 11pm and wake up at 7am you can stay up all day without feeling very sluggish? Does it have something to do with waking up while it’s still dark?

i go to sleep at 6am since i work nights, wake up around 11-13 most days and feel great, i can start to feel tired around 4-5am sometimes which is just before the light starts to rise.
But i also go to sleep with a movie playing and can see the light outside the curtains and have no issues
