how come if I go to bed at 10pm and wake up at 6am I feel great, but if I go to bed late and wake up late even though I get 8 hours I feel awful?

Question

I never understood this. If I go to bed early and wake up early I feel amazing. But if I go to bed late and wake up late I feel like shit (I don’t have a set routine I’m used to so it’s not that)

You get more deep sleep earlier in the night. Sleeping same hours on a delayed phase is less restful because you got less deep sleep.
