eli5: Why sleeping late and waking up late is worse than sleeping early and wake up early

Question

Lets say I sleep at 1am and wake up at 9am, why my body reacts negatively compared to sleep at 9 pm and wake up at 4 am. Both are 8 hours of sleeping time. How can my body knows it is past 12pm and decides to give me a bad day because of it.

Answer 1

There’s nothing inherently better about either. It’s just that most of society is organized around an earlier schedule so it’s harder, but absolutely not impossible, to take care of all your business and be productive if you’re a night owl.
